Convert struct target_ops to C++
I.e., use C++ virtual methods and inheritance instead of tables of
function pointers.
Unfortunately, there's no way to do a smooth transition. ALL native
targets in the tree must be converted at the same time. I've tested
all I could with cross compilers and with help from GCC compile farm,
but naturally I haven't been able to test many of the ports. Still, I
made a best effort to port everything over, and while I expect some
build problems due to typos and such, which should be trivial to fix,
I don't expect any design problems.
* Implementation notes:
- The flattened current_target is gone. References to current_target
or current_target.beneath are replaced with references to
target_stack (the top of the stack) directly.
- To keep "set debug target" working, this adds a new debug_stratum
layer that sits on top of the stack, prints the debug, and delegates
to the target beneath.
In addition, this makes the shortname and longname properties of
target_ops be virtual methods instead of data fields, and makes the
debug target defer those to the target beneath. This is so that
debug code sprinkled around that does "if (debugtarget) ..." can
transparently print the name of the target beneath.
A patch later in the series actually splits out the
shortname/longname methods to a separate structure, but I preferred
to keep that chance separate as it is associated with changing a bit
the design of how targets are registered and open.
- Since you can't check whether a C++ virtual method is overridden,
the old method of checking whether a target_ops implements a method
by comparing the function pointer must be replaced with something
else.
Some cases are fixed by adding a parallel "can_do_foo" target_ops
methods. E.g.,:
+ for (t = target_stack; t != NULL; t = t->beneath)
{
- if (t->to_create_inferior != NULL)
+ if (t->can_create_inferior ())
break;
}
Others are fixed by changing void return type to bool or int return
type, and have the default implementation return false or -1, to
indicate lack of support.
- make-target-delegates was adjusted to generate C++ classes and
methods.
It needed tweaks to grok "virtual" in front of the target method
name, and for the fact that methods are no longer function pointers.
(In particular, the current code parsing the return type was simple
because it could simply parse up until the '(' in '(*to_foo)'.
It now generates a couple C++ classes that inherit target_ops:
dummy_target and debug_target.
Since we need to generate the class declarations as well, i.e., we
need to emit methods twice, we now generate the code in two passes.
- The core_target global is renamed to avoid conflict with the
"core_target" class.
- ctf/tfile targets
init_tracefile_ops is replaced by a base class that is inherited by
both ctf and tfile.
- bsd-uthread
The bsd_uthread_ops_hack hack is gone. It's not needed because
nothing was extending a target created by bsd_uthread_target.
- remote/extended-remote targets
This is a first pass, just enough to C++ify target_ops.
A later pass will convert more free functions to methods, and make
remote_state be truly per remote instance, allowing multiple
simultaneous instances of remote targets.
- inf-child/"native" is converted to an actual base class
(inf_child_target), that is inherited by all native targets.
- GNU/Linux
The old weird double-target linux_ops mechanism in linux-nat.c, is
gone, replaced by adding a few virtual methods to linux-nat.h's
target_ops, called low_XXX, that the concrete linux-nat
implementations override. Sort of like gdbserver's
linux_target_ops, but simpler, for requiring only one
target_ops-like hierarchy, which spares implementing the same method
twice when we need to forward the method to a low implementation.
The low target simply reimplements the target_ops method directly in
that case.
There are a few remaining linux-nat.c hooks that would be better
converted to low_ methods like above too. E.g.:
linux_nat_set_new_thread (t, x86_linux_new_thread);
linux_nat_set_new_fork (t, x86_linux_new_fork);
linux_nat_set_forget_process
That'll be done in a follow up patch.
- We can no longer use functions like x86_use_watchpoints to install
custom methods on an arbitrary base target.
The patch replaces instances of such a pattern with template mixins.
For example memory_breakpoint_target defined in target.h, or
x86_nat_target in x86-nat.h.
- linux_trad_target, MIPS and Alpha GNU/Linux
The code in the new linux-nat-trad.h/c files which was split off of
inf-ptrace.h/c recently, is converted to a C++ base class, and used
by the MIPS and Alpha GNU/Linux ports.
- BSD targets
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between
the different BSDs. Currently, all that is stiched together to form
a final target, via the i386bsd_target, x86bsd_target,
fbsd_nat_add_target functions etc.
This introduces new fbsd_nat_target, obsd_nat_target and
nbsd_nat_target classes that serve as base/prototype target for the
corresponding BSD variant.
And introduces generic i386/AMD64 BSD targets, to be used as
template mixin to build a final target. Similarly, a generic SPARC
target is added, used by both BSD and Linux ports.
- bsd_kvm_add_target, BSD libkvm target
I considered making bsd_kvm_supply_pcb a virtual method, and then
have each port inherit bsd_kvm_target and override that method, but
that was resulting in lots of unjustified churn, so I left the
function pointer mechanism alone.

Add initial type alignment support
This adds some basic type alignment support to gdb. It changes struct
type to store the alignment, and updates dwarf2read.c to handle
DW_AT_alignment. It also adds a new gdbarch method and updates
i386-tdep.c.
None of this new functionality is used anywhere yet, so tests will
wait until the next patch.

Fix resolving GNU ifunc bp locations when inferior runs resolver
I noticed that if you set a breakpoint on an ifunc before the ifunc is
resolved, and then let the program call the ifunc, thus resolving it,
GDB end up with a location for that original breakpoint that is
pointing to the ifunc target, but it is left pointing to the first
address of the function, instead of after its prologue. After
prologue is what you get if you create a new breakpoint at that point.
1) With no debug info for the target function:
1.a) Set before resolving, and then program continued passed resolving:
Num Type Disp Enb Address What
1 breakpoint keep y 0x0000000000400753 <final>
1.b) Breakpoint set after inferior resolved ifunc:
Num Type Disp Enb Address What
2 breakpoint keep y 0x0000000000400757 <final+4>
2) With debug info for the target function:
1.a) Set before resolving, and then program continued passed resolving:
Num Type Disp Enb Address What
1 breakpoint keep y 0x0000000000400753 in final at gdb/testsuite/gdb.base/gnu-ifunc-final.c:20
1.b) Breakpoint set after inferior resolved ifunc:
Num Type Disp Enb Address What
2 breakpoint keep y 0x000000000040075a in final at gdb/testsuite/gdb.base/gnu-ifunc-final.c:21
The problem is that elf_gnu_ifunc_resolver_return_stop (called by the
internal breakpoint that traps the resolver returning) does not agree
with linespec.c:minsym_found. It does not skip to the function's
start line (i.e., past the prologue). We can now use the
find_function_start_sal overload added by the previous commmit to fix
this.
New tests included, which fail before the patch, and pass afterwards.
gdb/ChangeLog:
2018-04-26 Pedro Alves <palves@redhat.com>
* elfread.c (elf_gnu_ifunc_resolver_return_stop): Use
find_function_start_sal instead of find_pc_line.

For PPC64/ELFv1: Introduce mst_data_gnu_ifunc
Running the new tests added later in the series on PPC64 (ELFv1)
revealed that the current ifunc support needs a bit of a design rework
to work properly on PPC64/ELFv1, as most of the new tests fail. The
ifunc support only kind of works today if the ifunc symbol and the
resolver have the same name, as is currently tested by the
gdb.base/gnu-ifunc.exp testcase, which is unlike how ifuncs are
written nowadays.
The crux of the problem is that ifunc symbols are really function
descriptors, not text symbols:
44: 0000000000020060 104 FUNC GLOBAL DEFAULT 18 gnu_ifunc_resolver
54: 0000000000020060 104 GNU_IFUNC GLOBAL DEFAULT 18 gnu_ifunc
But, currently GDB only knows about ifunc symbols that are text
symbols. GDB's support happens to work in practice for PPC64 when the
ifunc and resolver are one and only, like in the current
gdb.base/gnu-ifunc.exp testcase:
15: 0000000000020060 104 GNU_IFUNC GLOBAL DEFAULT 18 gnu_ifunc
because in that case, the synthetic ".gnu_ifunc" entry point text
symbol that bfd creates from the actual GNU ifunc "gnu_ifunc" function
(descriptor) symbol ends up with the the "is a gnu ifunc" flag set /
copied over:
(gdb) maint print msymbols
...
[ 8] i 0x9c4 .gnu_ifunc section .text <<< mst_text_gnu_ifunc
...
[29] D 0x20060 gnu_ifunc section .opd crtstuff.c <<< mst_data
But, if the resolver gets a distinct symbol/name from the ifunc
symbol, then we end up with this:
(gdb) maint print msymbols
[ 8] T 0x9e4 .gnu_ifunc_resolver section .text <<< mst_text
...
[29] D 0x20060 gnu_ifunc section .opd crtstuff.c <<< mst_data
[30] D 0x20060 gnu_ifunc_resolver section .opd crtstuff.c <<< mst_data
I have a follow up bfd patch that turns that into:
(gdb) maint print msymbols
+ [ 8] i 0x9e4 .gnu_ifunc section .text <<< mst_text_gnu_ifunc
[ 8] T 0x9e4 .gnu_ifunc_resolver section .text <<< mst_text
...
[29] D 0x20060 gnu_ifunc section .opd crtstuff.c
[30] D 0x20060 gnu_ifunc_resolver section .opd crtstuff.c
but that won't help everything. We still need this patch.
Specifically, when we do a symbol lookup by name, like e.g., to call a
function (see c-exp.y hunk), e.g., "p gnu_ifunc()", then we need to
know that the found "gnu_ifunc" minimal symbol is an ifunc in order to
do some special processing. But, on PPC, that lookup by name finds
the function descriptor symbol, which presently is just a mst_data
symbol, while at present, we look for mst_text_gnu_ifunc symbols to
decide whether to do special GNU ifunc processing. In most of those
places, we could try to resolve the function descriptor with
gdbarch_convert_from_func_ptr_addr, and then lookup the minimal symbol
at the resolved PC, see if that finds a minimal symbol of type
mst_text_gnu_ifunc. If so, then we could assume that the original
mst_dadta / function descriptor "gnu_ifunc" symbol was an ifunc. I
tried it, and it mostly works, even if it's not the most efficient.
However, there's one case that can't work with such a design -- it's
that of the user calling the ifunc resolver directly to debug it, like
"p gnu_ifunc_resolver(0)", expecting that to return the function
pointer of the final function (which is exercised by the new tests
added later). In this case, with the not-fully-working solution, we'd
resolve the function descriptor, find that there's an
mst_text_gnu_ifunc symbol for the resolved address, and proceed
calling the function as if we tried to call "gnu_ifunc", the
user-visible GNU ifunc symbol, instead of the resolver. I.e., it'd be
impossible to call the resolver directly as a normal function.
Introducing mst_data_gnu_ifunc eliminates the need for several
gdbarch_convert_from_func_ptr_addr calls, and, fixes the "call
resolver directly" use case mentioned above too. It's the cleanest
approach I could think of.
In sum, we make GNU ifunc function descriptor symbols get a new
"mst_data_gnu_ifunc" minimal symbol type instead of the bare mst_data
type. So when symbol lookup by name finds such a minimal symbol, we
know we found an ifunc symbol, without resolving the entry/text
symbol. If the user calls the the resolver symbol instead, like "p
gnu_ifunc_resolver(0)", then we'll find the regular mst_data symbol
for "gnu_ifunc_resolver", and we'll call the resolver function as just
another regular function.
With this, most of the GNU ifunc tests added by a later patch pass on
PPC64 too. The following bfd patch fixes the remaining issues.

Breakpoints, don't skip prologue of ifunc resolvers with debug info
Without this patch, some of the tests added to gdb.base/gnu-ifunc.exp
by a following patch fail like so:
FAIL: gdb.base/gnu-ifunc.exp: resolver_attr=0: resolver_debug=1: resolved_debug=0: set-break: before resolving: break gnu_ifunc
FAIL: gdb.base/gnu-ifunc.exp: resolver_attr=0: resolver_debug=1: resolved_debug=0: set-break: before resolving: info breakpoints

FAIL: gdb.base/gnu-ifunc.exp: resolver_attr=0: resolver_debug=1: resolved_debug=1: set-break: before resolving: break gnu_ifunc
FAIL: gdb.base/gnu-ifunc.exp: resolver_attr=0: resolver_debug=1: resolved_debug=1: set-break: before resolving: info breakpoints
FAIL: gdb.base/gnu-ifunc.exp: resolver_attr=0: resolver_debug=1: resolved_debug=1: set-break: after resolving: break gnu_ifunc
FAIL: gdb.base/gnu-ifunc.exp: resolver_attr=0: resolver_debug=1: resolved_debug=1: set-break: after resolving: info breakpoints
All of them trigger iff:
- you have debug info for the ifunc resolver.
- the resolver and the user-visible symbol have the same name.
If you have an ifunc that has a resolver with the same name as the
user visible symbol, debug info for the resolver masks out the ifunc
minsym. When you set a breakpoint by name on the user visible symbol,
GDB finds the DWARF symbol for the resolver, and thinking that it's a
regular function, sets a breakpoint location past its prologue.
Like so, location 1.2, before the ifunc is resolved by the inferior:
(gdb) break gnu_ifunc
Breakpoint 2 at 0x7ffff7bd36ea (2 locations)
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
1.1 y 0x00007ffff7bd36ea <gnu_ifunc>
1.2 y 0x00007ffff7bd36f2 in gnu_ifunc at src/gdb/testsuite/gdb.base/gnu-ifunc-lib.c:34
(gdb)
And like so, location 2.2, if you set the breakpoint after the ifunc
is resolved by the inferior (to "final"):
(gdb) break gnu_ifunc
Breakpoint 5 at 0x400757 (2 locations)
(gdb) info breakpoints
Num Type Disp Enb Address What
2 breakpoint keep y <MULTIPLE>
2.1 y 0x000000000040075a in final at src/gdb/testsuite/gdb.base/gnu-ifunc-resd.c:21
2.2 y 0x00007ffff7bd36f2 in gnu_ifunc at src/gdb/testsuite/gdb.base/gnu-ifunc-lib.c:34
(gdb)
I don't think this is right because when users set a breakpoint at an
ifunc, they don't care about debugging the resolver. Instead what you
should is a single location for the ifunc in the first case, and a
single location of the ifunc target in the second case.

Fix setting breakpoints on ifunc functions after they're already resolved
This fixes setting breakpoints on ifunc functions by name after the
ifunc has already been resolved.
In that case, if you have debug info for the ifunc resolver, without
the fix, then gdb puts a breakpoint past the prologue of the resolver,
instead of setting a breakpoint at the ifunc target:
break gnu_ifunc
Breakpoint 4 at 0x7ffff7bd36f2: file src/gdb/testsuite/gdb.base/gnu-ifunc-lib.c, line 34.
(gdb) continue
Continuing.
[Inferior 1 (process 13300) exited normally]
(gdb)
above we should have stopped at "final", but didn't because we never
resolved the ifunc to the final location.
If you don't have debug info for the resolver, GDB manages to resolve
the ifunc target, but, it should be setting a breakpoint after the
prologue of the final function, and instead what you get is that GDB
sets a breakpoint on the first address of the target function. With
the gnu-ifunc.exp tests added by a later patch, we get, without the
fix:
(gdb) break gnu_ifunc
Breakpoint 4 at 0x400753
(gdb) continue
Continuing.
Breakpoint 4, final (arg=1) at src/gdb/testsuite/gdb.base/gnu-ifunc-final.c:20
20 {
vs, fixed:
(gdb) break gnu_ifunc
Breakpoint 4 at 0x40075a: file src/gdb/testsuite/gdb.base/gnu-ifunc-final.c, line 21.
(gdb) continue
Continuing.
Breakpoint 4, final (arg=2) at src/gdb/testsuite/gdb.base/gnu-ifunc-final.c:21
21 return arg + 1;
(gdb)
Fix the problems above by moving the ifunc target resolving to
linespec.c, before we skip a function's prologue. We need to save
something in the sal, so that set_breakpoint_location_function knows
that it needs to create a bp_gnu_ifunc_resolver bp_location. Might as
well just save a pointer to the minsym.

Calling ifunc functions when resolver has debug info, user symbol same name
If the GNU ifunc resolver has the same name as the user visible
symbol, and the resolver has debug info, then the DWARF info for the
resolver masks the ifunc minsym. In that scenario, if you try calling
the ifunc from GDB, you call the resolver instead. With the
gnu-ifunc.exp testcase added in a following patch, you'd see:
(gdb) p gnu_ifunc (3)
$1 = (int (*)(int)) 0x400753 <final>
(gdb) FAIL: gdb.base/gnu-ifunc.exp: resolver_attr=0: resolver_debug=1: resolved_debug=0: p gnu_ifunc (3)
^^^^^^^^^^^^^^^^
That is, we called the ifunc resolver manually, which returned a
pointer to the ifunc target function ("final"). The "final" symbol is
the function that GDB should have called automatically,
~~~~~~~~~~~~
int
final (int arg)
{
return arg + 1;
}
~~~~~~~~~
which is what happens if you don't have debug info for the resolver:
(gdb) p gnu_ifunc (3)
$1 = 4
(gdb) PASS: gdb.base/gnu-ifunc.exp: resolver_attr=0: resolver_debug=0: resolved_debug=1: p gnu_ifunc (3)
^^^^^^^^^^^^^^^^
or if the resolver's symbol has a different name from the ifunc (as is
the case with modern uses of ifunc via __attribute__ ifunc, such as
glibc uses):
(gdb) p gnu_ifunc (3)
$1 = 4
(gdb) PASS: gdb.base/gnu-ifunc.exp: resolver_attr=1: resolver_debug=1: resolved_debug=0: p gnu_ifunc (3)
^^^^^^^^^^^^^^^
in which case after this patch, you can still call the resolver
directly if you want:
(gdb) p gnu_ifunc_resolver (3)
$1 = (int (*)(int)) 0x400753 <final>

Calling ifunc functions when target has no debug info but resolver has
After the previous patch, on Fedora 27 (glibc 2.26), if you try
calling strlen in the inferior, you now get:
(top-gdb) p strlen ("hello")
'__strlen_avx2' has unknown return type; cast the call to its declared return type
This is correct, because __strlen_avx2 is written in assembly.
We can improve on this though -- if the final ifunc resolved/target
function has no debug info, but the ifunc _resolver_ does have debug
info, we can try extracting the final function's type from the type
that the resolver returns. E.g.,:
typedef size_t (*strlen_t) (const char*);
size_t my_strlen (const char *) { /* some implementation */ }
strlen_t strlen_resolver (unsigned long hwcap) { return my_strlen; }
extern size_t strlen (const char *s);
__typeof (strlen) strlen __attribute__ ((ifunc ("strlen_resolver")));
In the strlen example above, the resolver returns strlen_t, which is a
typedef for pointer to a function that returns size_t. "strlen_t" is
the type of both the user-visible "strlen", and of the the target
function that implements it.
This patch teaches GDB to extract that type.
This is done for actual inferior function calls (in infcall.c), and
for ptype (in eval_call). By the time we get to either of these
places, we've already lost the original symbol/minsym, and only have
values and types to work with. Hence the changes to c-exp.y and
evaluate_var_msym_value, to ensure that we propagate the ifunc
minsymbol's info.
The change to make ifunc symbols have no/unknown return type exposes a
latent problem -- gdb.compile/compile-ifunc.exp calls a no-debug-info
function, but we did not warn about it. The test is fixed by this
commit too.

Fix calling ifunc functions when resolver has debug info and different name
Currently, on Fedora 27 (glibc 2.26), if you try to call strlen in the
inferior you get:
(gdb) p strlen ("hello")
$1 = (size_t (*)(const char *)) 0x7ffff554aac0 <__strlen_avx2>
strlen is an ifunc function, and what we see above is the result of
calling the ifunc resolver in the inferior. That returns a pointer to
the actual target function that implements strlen on my machine. GDB
should have turned around and called the resolver automatically
without the user noticing.
This is was caused by commit:
commit bf223d3e808e6fec9ee165d3d48beb74837796de
Date: Mon Aug 21 11:34:32 2017 +0100
Handle function aliases better (PR gdb/19487, errno printing)
which added the find_function_alias_target call to c-exp.y, to try to
find an alias with debug info for a minsym. For ifunc symbols, that
finds the ifunc's resolver if it has debug info (in the example it's
called "strlen_ifunc"), with the result that GDB calls that as a
regular function.
After this commit, we get now get:
(top-gdb) p strlen ("hello")
'__strlen_avx2' has unknown return type; cast the call to its declared return type
Which is correct, because __strlen_avx2 is written in assembly.
That'll be improved in a following patch, though.

Fix breakpoints in ifunc after inferior resolved it (@got.plt symbol creation)
Setting a breakpoint on an ifunc symbol after the ifunc has already
been resolved by the inferior should result in creating a breakpoint
location at the ifunc target. However, that's not what happens on
current Fedora:
(gdb) n
53 i = gnu_ifunc (1); /* break-at-call */
(gdb)
54 assert (i == 2);
(gdb) b gnu_ifunc
Breakpoint 2 at gnu-indirect-function resolver at 0x7ffff7bd36ee
(gdb) info breakpoints
Num Type Disp Enb Address What
2 STT_GNU_IFUNC resolver keep y 0x00007ffff7bd36ee <gnu_ifunc+4>
The problem is that elf_gnu_ifunc_resolve_by_got never manages to
resolve an ifunc target. The reason is that GDB never actually
creates the internal got.plt symbols:
(gdb) p 'gnu_ifunc@got.plt'
No symbol "gnu_ifunc@got.plt" in current context.
and this is because GDB expects that rela.plt has relocations for
.plt, while it actually has relocations for .got.plt:
Relocation section [10] '.rela.plt' for section [22] '.got.plt' at offset 0x570 contains 2 entries:
Offset Type Value Addend Name
0x0000000000601018 X86_64_JUMP_SLOT 000000000000000000 +0 __assert_fail
0x0000000000601020 X86_64_JUMP_SLOT 000000000000000000 +0 gnu_ifunc
Using an older system on the GCC compile farm (machine gcc15, an
x86-64 running Debian 6.0.8, with GNU ld 2.20.1), we see that it used
to be that we'd get a .rela.plt section for .plt:
Relocation section [ 9] '.rela.plt' for section [11] '.plt' at offset 0x578 contains 3 entries:
Offset Type Value Addend Name
0x0000000000600cc0 X86_64_JUMP_SLOT 000000000000000000 +0 __assert_fail
0x0000000000600cc8 X86_64_JUMP_SLOT 000000000000000000 +0 __libc_start_main
0x0000000000600cd0 X86_64_JUMP_SLOT 000000000000000000 +0 gnu_ifunc
Those offsets did point into .got.plt, as seen with objdump -h:
20 .got.plt 00000030 0000000000600ca8 0000000000600ca8 00000ca8 2**3
CONTENTS, ALLOC, LOAD, DATA
I also tested on gcc110 on the compile farm (PPC64 running CentOS
7.4.1708, with GNU ld 2.25.1), and there we see instead:
Relocation section [ 9] '.rela.plt' for section [23] '.plt' at offset 0x5d0 contains 4 entries:
Offset Type Value Addend Name
0x0000000010020148 PPC64_JMP_SLOT 000000000000000000 +0 __libc_start_main
0x0000000010020160 PPC64_JMP_SLOT 000000000000000000 +0 __gmon_start__
0x0000000010020178 PPC64_JMP_SLOT 000000000000000000 +0 __assert_fail
0x0000000010020190 PPC64_JMP_SLOT 000000000000000000 +0 gnu_ifunc
But note that those offsets point into .plt, not .got.plt, as seen
with objdump -h:
22 .plt 00000078 0000000010020130 0000000010020130 00010130 2**3
ALLOC
This commit makes us support all the different combinations above.
With that addressed, we now get:
(gdb) p 'gnu_ifunc@got.plt'
$1 = (<text from jump slot in .got.plt, no debug info>) 0x400753 <final>
And setting a breakpoint on the ifunc finds the ifunc target:
(gdb) b gnu_ifunc
Breakpoint 2 at 0x400753
(gdb) info breakpoints

Fix new inferior events output
Since f67c0c917150 ("Enable 'set print inferior-events' and improve
detach/fork/kill/exit messages"), when detaching a remote process, we
get, for detach against a remote target:
(gdb) detach
Detaching from program: ...., process 5388
Ending remote debugging.
[Inferior 1 (Thread 5388.5388) detached]
^^^^^^^^^^^^^^^^
That is incorrect, for it is printing a thread id as string while we
should be printing the process id instead. I.e., either one of:
[Inferior 1 (process 5388) detached]
[Inferior 1 (Remote target) detached]
depending on remote stub support for the multi-process extensions.
Similarly, after killing a process, we're printing thread ids while we
should be printing process ids. E.g., on native GNU/Linux:
(gdb) k
Kill the program being debugged? (y or n) y
[Inferior 1 (Thread 0x7ffff7faa8c0 (LWP 30721)) has been killed]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
while it should have been:
Kill the program being debugged? (y or n) y
[Inferior 1 (process 30721) has been killed]
^^^^^^^^^^^^^
There's a wording inconsistency between detach and kill:
[Inferior 1 (process 30721) has been killed]
[Inferior 1 (process 30721) detached]
Given we were already saying "detached" instead of "has been
detached", and we used to say just "exited", and given that the "has
been" doesn't really add any information, this commit changes the
message to just "killed":
[Inferior 1 (process 30721) killed]

Enable 'set print inferior-events' and improve detach/fork/kill/exit messages
This patch aims to turn 'set print inferior-events' always on, and do
some cleanup on the messages printed by GDB when various inferior
events happen (attach, detach, fork, kill, exit).
To make sure that the patch is correct, I've tested it with a handful
of combinations of 'set follow-fork-mode', 'set detach-on-fork' and
'set print inferior-events'. In the end, I decided to make my
hand-made test into an official testcase. More on that below.
Using the following program as an example:
#include <unistd.h>
int main ()
{
fork ();
return 0;
}
We see the following outputs from the patched GDB:
- With 'set print inferior-events on':
(gdb) r
Starting program: a.out
[Detaching after fork from child process 27749]
[Inferior 1 (process 27745) exited normally]
(gdb)
- With 'set print inferior-events off':
(gdb) r
Starting program: a.out
[Inferior 1 (process 27823) exited normally]
(gdb)
Comparing this against an unpatched GDB:
- With 'set print inferior-events off' and 'set follow-fork-mode
child':
(gdb) r
Starting program: a.out
[Inferior 2 (process 5993) exited normally]
(gdb)
Compare this against an unpatched GDB:
(unpatched-gdb) r
Starting program: a.out
[New process 5702]
[Inferior 2 (process 5702) exited normally]
(unpatched-gdb)
It is possible to notice that, in this scenario, the patched GDB
will lose the '[New process %d]' message.
- With 'set print inferior-events on', 'set follow-fork-mode child'
and 'set detach-on-fork on':
(gdb) r
Starting program: a.out
[Attaching after process 27905 fork to child process 27909]
[New inferior 2 (process 27909)]
[Detaching after fork from parent process 27905]
[Inferior 1 (process 27905) detached]
[Inferior 2 (process 27909) exited normally]
(gdb)
Compare this output with an unpatched GDB, using the same settings:
(unpatched-gdb) r
Starting program: a.out
[New inferior 28033]
[Inferior 28029 detached]
[New process 28033]
[Inferior 2 (process 28033) exited normally]
[Inferior 28033 exited]
(unpatched-gdb)
As can be seen above, I've also made a few modifications to messages
that are printed when 'set print inferior-events' is on. For example,
a few of the messages did not contain the '[' and ']' as
prefix/suffix, which led to a few inconsistencies like:
Attaching after process 22995 fork to child process 22999.
[New inferior 22999]
Detaching after fork from child process 22999.
[Inferior 22995 detached]
[Inferior 2 (process 22999) exited normally]
So I took the opportunity and included the square brackets where
applicable. I have also made the existing messages more uniform, by
always printing "Inferior %d (process %d)..." where applicable. This
makes it easier to identify the inferior number and the PID number
from the messages.
As suggested by Pedro, the "[Inferior %d exited]" message from
'exit_inferior' has been removed, because it got duplicated when
'inferior-events' is on. I'm also using the
'add_{thread,inferior}_silent' versions (instead of their verbose
counterparts) on some locations, also to avoid duplicated messages.
For example, a patched GDB with 'set print inferior-events on', 'set
detach-on-fork on' and 'set follow-fork-mode child', but using
'add_thread', would print:
(gdb) run
Starting program: a.out
[Attaching after process 25088 fork to child process 25092.]
[New inferior 25092] <--- duplicated
[Detaching after fork from child process 25092.]
[Inferior 25088 detached]
[New process 25092] <--- duplicated
[Inferior 2 (process 25092) exited normally]
But if we use 'add_thread_silent' (with the same configuration as
before):
(gdb) run
Starting program: a.out
[Attaching after process 31606 fork to child process 31610]
[New inferior 2 (process 31610)]
[Detaching after fork from parent process 31606]
[Inferior 1 (process 31606) detached]
[Inferior 2 (process 31610) exited normally]
As for the tests, the configuration options being exercised are:
- follow-fork-mode: child/parent
- detach-on-fork: on/off
- print inferior-events: on/off
It was also necessary to perform adjustments on several testcases,
because the expected messages changed considerably.
Built and regtested on BuildBot, without regressions.

FreeBSD: Fix 'Couldn't get registers: Device busy' error (PR gdb/23077)
As Rajendra SY reported at
<https://sourceware.org/ml/gdb-patches/2018-04/msg00399.html>, several
attach-related tests are failing on FreeBSD. The "attach" command
errors with "Couldn't get registers: Device busy".
When the "attach" command is executed, it calls target_attach ->
inf_ptrace_attach, which just does the ptrace(PT_ATTACH), it does not
wait for the child to stop with SIGSTOP. Afterwards, the command is
complete and we go back to the event loop. The event loop wakes up
and we end up in target_wait -> fbsd_wait, and handle the SIGSTOP
stop.
At the end of execute_command, though, before going back to the event
loop, we check if the frame language changed via
check_frame_language_change(). That reads the current PC, which is
what leads to the registers read that fails.
The problem is that we fail to mark the attached-to thread as
executing between the initial attach, and the subsequent target_wait.
Until we see the thread stop with SIGSTOP, we shouldn't try to read
registers off of it. I guess there may a timing issue here - if
you're "lucky", the thread may stop before gdb reads its registers,
masking the problem.
With that fixed, check_frame_language_change() becomes a nop until the
thread is marked not-executing again, after target_wait is called and
we go through handle_inferior_event -> normal_stop.
We haven't seen the problem on Linux because there, the target_attach
implementation waits for the thread to stop before returning. Still,
that's supposedly hidden from the core, since the Linux target, like
most targets, is a '!to_attach_no_wait' target.
This fixes:

Don't print symbol declaration's line number in rbreak output
This commit:
b744723f57 -- Show line numbers in output for "info var/func/type"
adds the symbol declaration's line number to the output of certain GDB
commands. It also (inadvertently) changes the `rbreak' command's output,
like this:
(gdb) rbreak foo
Breakpoint 1 at 0x40049b: file rbreak.c, line 6.
4: static int foo1(void);
Breakpoint 2 at 0x4004b1: file rbreak.c, line 12.
10: static int foo2(void);
(gdb)
where the function declaration is now prefixed by its source line number,
followed by a colon. But without showing the declaration's file name, the
line number is useless and can possibly cause severe confusion.
No declaration line number was shown before. Instead, the function
declaration started at the first column:
(gdb) rbreak foo
Breakpoint 1 at 0x40049b: file rbreak.c, line 6.
static int foo1(void);
Breakpoint 2 at 0x4004b1: file rbreak.c, line 12.
static int foo2(void);
(gdb)
This old behavior is restored, fixing some FAILs in fullpath-expand.exp,
realname-expand.exp, and pr10179.exp.
In order to distinguish when to print location information, the meaning of
print_symbol_info()'s parameter `last' is changed. Now NULL means to skip
any filename or line number information. Previously NULL meant to always
print the filename.
gdb/ChangeLog:
* symtab.c (print_symbol_info): Skip printing filename and line
number when `last' is NULL.
(symtab_symbol_info): Use empty string instead of NULL for first
invocation of print_symbol_info.
(rbreak_command): Pass NULL to `last' parameter of
print_symbol_info.

infrun: step through indirect branch thunks
With version 7.3 GCC supports new options
-mindirect-branch=<choice>
-mfunction-return=<choice>
The choices are:
keep behaves as before
thunk jumps through a thunk
thunk-external jumps through an external thunk
thunk-inline jumps through an inlined thunk
For thunk and thunk-external, GDB would, on a call to the thunk, step into
the thunk and then resume to its caller assuming that this is an
undebuggable function. On a return thunk, GDB would stop inside the
thunk.
Make GDB step through such thunks instead.
Before:
Temporary breakpoint 1, main ()
at gdb.base/step-indirect-call-thunk.c:37
37 x = apply (inc, 41);
(gdb) s
apply (op=0x80483e6 <inc>, x=41)
at gdb.base/step-indirect-call-thunk.c:29
29 return op (x);
(gdb)
30 }
After:
Temporary breakpoint 1, main ()
at gdb.base/step-indirect-call-thunk.c:37
37 x = apply (inc, 41);
(gdb) s
apply (op=0x80483e6 <inc>, x=41)
at gdb.base/step-indirect-call-thunk.c:29
29 return op (x);
(gdb)
inc (x=41) at gdb.base/step-indirect-call-thunk.c:23
23 return x + 1;
This is independent of the step-mode. In order to step into the thunk,
you would need to use stepi.
When stepping over an indirect call thunk, GDB would first step through
the thunk, then recognize that it stepped into a sub-routine and resume to
the caller (of the thunk). Not sure whether this is worth optimizing.
Thunk detection is implemented via gdbarch. I implemented the methods for
IA. Other architectures may run into unexpected fails.
The tests assume a fixed number of instruction steps to reach a thunk.
This depends on the compiler as well as the architecture. They may need
adjustments when we add support for more architectures. Or we can simply
drop those tests that cover being able to step into thunks using
instruction stepping.
When using an older GCC, the tests will fail to build and will be reported
as untested:
Running .../gdb.base/step-indirect-call-thunk.exp ...

File I/O file handles after target closes
A future patch will propose making the remote target's target_ops be
heap-allocated (to make it possible to have multiple instances of
remote targets, for multiple simultaneous connections), and will
delete/destroy the remote target at target_close time.
That change trips on a latent problem, though. File I/O handles
remain open even after the target is gone, with a dangling pointer to
a target that no longer exists. This results in GDB crashing when it
calls the target_ops backend associated with the file handle:
(gdb) Disconnect
Ending remote debugging.
* GDB crashes deferencing a dangling pointer

This goes unnoticed in current master, because the current remote
target's target_ops is never destroyed nowadays, so we end up calling:
remote_hostio_close -> remote_hostio_send_command
which gracefully fails with FILEIO_ENOSYS if remote_desc is NULL
(because the target is closed).
Fix this by invalidating a target's file I/O handles when the target
is closed.
With this change, remote_hostio_send_command no longer needs to handle the
case of being called with a closed remote target, originally added here:
<https://sourceware.org/ml/gdb-patches/2008-08/msg00359.html>.

Iterate by index in auto_load_safe_path_vec_update
As reported by Jan, we get this error when building with -D_GLIBCXX_DEBUG:
/usr/include/c++/7/debug/safe_iterator.h:297:
Error: attempt to increment a singular iterator.
Objects involved in the operation:
iterator "this" @ 0x0x7fffffffd140 {

}
The bug was introduced by commit
commit e80aaf6183c6692ecc167bf26cbdc53f8f1a55f0
Author: Simon Marchi <simon.marchi@polymtl.ca>
Date: Fri Mar 2 23:22:06 2018 -0500
Make delim_string_to_char_ptr_vec return an std::vector
The problem is that we iterate using a range-based for on a vector to
which we push in the loop. Pushing to the vector invalidates the
iterator used in the loop. Instead, change the code to iterate by index
as was done in the previous code.
gdb/ChangeLog:
* auto-load.c (auto_load_safe_path_vec_update): Iterate by
index.

Add gdb::string_view
We had a few times the need for a data structure that does essentially
what C++17's std::string_view does, which is to give an std::string-like
interface (only the read-only operations) to an arbitrary character
buffer.
This patch adapts the files copied from libstdc++ by the previous patch
to integrate them with GDB. Here's a summary of the changes:
* Remove things related to wstring_view, u16string_view and
u32string_view (I don't think we need them, but we can always add them
later).
* Remove usages of _GLIBCXX_BEGIN_NAMESPACE_VERSION and
_GLIBCXX_END_NAMESPACE_VERSION.
* Put the code in the gdb namespace. I had to add a few "std::" in
front of std type usages.
* Change __throw_out_of_range_fmt() for error().
* Make gdb::string_view an alias of std::string_view when building
with >= c++17.
* Remove a bunch of constexpr, because they are not valid in c++11
(e.g. they are not a single return line).
* Use std::common_type<_Tp>::type instead of std::common_type_t<_Tp>,
because c++11 doesn't have the later.
* Remove the #pragma GCC system_header, since that silences some
warnings that we might want to have if we're doing something not
correctly.
* Remove operator ""sv. It would need a lot of work to make all
supported compilers happy, and we can easily live without it.
* Remove operator<<. It is implemented using __ostream_insert (a
libstdc++ internal). Bringing it in might be possible, but I don't
think that would be worth the effort, since we don't really use
streams at the moment.
* Replace internal libstdc++ asserts ( __glibcxx_assert and
__glibcxx_requires_string_len) with gdb_assert.
* Remove hash helpers, because they use libstdc++ internal functions.
If we need them we always import them later.
The string_view class in cli/cli-script.c is removed and its usage
replaced with the new gdb::string_view.

Implement write_async_safe for mi_console_file (PR 22299)
Enabling "set debug lin-lwp 1" with the MI interpreter doesn't work.
When the sigchld_handler function wants to print a debug output
("sigchld\n"), it uses ui_file_write_async_safe. This ends up in the
default implementation of ui_file::write_async_safe, which aborts GDB.
This patch implements the write_async_safe method for mi_console_file.
The "normal" MI output is line buffered, which means the output
accumulates in m_buffer until a \n is written, at which point it's
flushed in m_raw. The implementation of write_async_safe provided by
this patch bypasses this buffer and writes directly to m_raw. There are
two reasons for this:
(1) Appending to m_buffer (therefore to an std::string) is probably not
async-safe, as it may allocate memory.
(2) We may have a partial output already in m_buffer, so that would lead
to some nested MI output, not so great.
There is probably still a chance to have bad MI output, if
sigchld_handler is invoked in the middle of mi_console_file's flush, and
the line being flushed is only partially sent to m_raw. The solution
would probably be to block signals during flushing. Since this is only
used for debug output, I don't know if it's worth the effort to do that.
To implement write_async_safe, I needed to use the fputstrn_unfiltered,
which does the necessary escaping (e.g. replace \n with \\n). I started
by adding printchar's callback parameters to fputstrn_unfiltered, to be
able to pass async-safe versions of them. It's not easy to provide an
async-safe version of do_fprintf, but it turns out that we can easily
replace printchar's callbacks with a single do_fputc quite easily. The
async-safe version of do_fputc simply calls the underlying ui_file's
write_async_safe method.

Fix generation of x86-64 gdbarch with osabi none (PR 22979)
When a 64-bits (x86-64) gdbarch is created, it is first born as a
32-bits gdbarch in i386_gdbarch_init. The call gdbarch_init_osabi will
call the handler register for the selected (arch, osabi) pair, such as
amd64_linux_init_abi. The various amd64 handlers call amd64_init_abi,
which turns the gdbarch into a 64-bits one.
When selecting the i386:x86-64 architecture with no osabi, no such
handler is ever called, so the gdbarch stays (wrongfully) a 32-bits one.
My first idea was to manually call amd64_init_abi & al in
i386_gdbarch_init when the osabi is GDB_OSABI_NONE. However, this
doesn't work in a build of GDB where i386 is included as a target but
not amd64. My next option (implemented in this patch), is to allow
registering handlers for GDB_OSABI_NONE. I added two such handlers in
amd64-tdep.c, so now it works the same as for the "normal" osabis. It
required re-ordering things in gdbarch_init_osabi to allow running
handlers for GDB_OSABI_NONE.
Without this patch applied (but with the previous one*) :
(gdb) set osabi none
(gdb) set architecture i386:x86-64
The target architecture is assumed to be i386:x86-64

Make "set osabi none" really work (PR 22980)
I was looking for a way to reproduce easily PR 22979 by doing this:
(gdb) set architecture i386:x86-64
(gdb) set osabi none
However, I noticed that even though I did "set osabi none", the gdbarch
gdb created was for Linux:
(gdb) set debug arch 1
(gdb) set architecture i386:x86-64
...
(gdb) set osabi none
gdbarch_find_by_info: info.bfd_arch_info i386:x86-64
gdbarch_find_by_info: info.byte_order 1 (little)
gdbarch_find_by_info: info.osabi 4 (GNU/Linux) <--- Wrong?
gdbarch_find_by_info: info.abfd 0x0
gdbarch_find_by_info: info.tdep_info 0x0
gdbarch_find_by_info: Previous architecture 0x1e6fd30 (i386:x86-64)
selected
gdbarch_update_p: Architecture 0x1e6fd30 (i386:x86-64) unchanged
This is because the value GDB_OSABI_UNKNOWN has an unclear role,
sometimes meaning "no osabi" and sometimes "please selected
automatically". Doing "set osabi none" sets the requested osabi to
GDB_OSABI_UNKNOWN, in which case gdbarch_info_fill overrides it with a
value from the target description, or the built-in default osabi. This
means that it's impossible to force GDB not to use an osabi with "set
osabi". Since my GDB's built-in default osabi is Linux, it always falls
back to GDB_OSABI_LINUX.
To fix it, I introduced GDB_OSABI_NONE, which really means "I don't want
any osabi". GDB_OSABI_UNKNOWN can then be used only for "not set yet,
please auto-detect". GDB_OSABI_UNINITIALIZED now seems unnecessary
since it overlaps with GDB_OSABI_UNKNOWN, so I think it can be removed
and gdbarch_info::osabi can be initialized to GDB_OSABI_UNKNOWN.

Make target_read_alloc & al return vectors
This patch started by changing target_read_alloc_1 to return a
byte_vector, to avoid manual memory management (in target_read_alloc_1
and in the callers). To communicate failures to the callers, it
actually returns a gdb::optional<gdb::byte_vector>.
Adjusting target_read_stralloc was a bit more tricky, since it wants to
return a buffer of char, and not gdb_byte. Since you can't just cast a
gdb::byte_vector into a gdb::def_vector<char>, I made
target_read_alloc_1 templated, so both versions (that return vectors of
gdb_byte and char) are generated. Since target_read_stralloc now
returns a gdb::char_vector instead of a gdb::unique_xmalloc_ptr<char>, a
few callers need to be adjusted.

Introduce a gdb_ref_ptr specialization for struct value
struct value is internally reference counted and so, while it also has
some ownership rules unique to it, it makes sense to use a gdb_ref_ptr
when managing it automatically.
This patch removes the existing unique_ptr specialization in favor of
a reference-counted pointer. It also introduces two other
clarifications:
1. Rename value_free to value_decref, which I think is more in line
with what the function actually does; and
2. Change release_value to return a gdb_ref_ptr. This change allows
us to remove the confusing release_value_or_incref function,
primarily by making it much simpler to reason about the result of
release_value.

Move DWARF index-related things to a separate file
I want to add a DWARF index-related feature (automatically produce index
files when loading objfiles in GDB), but I don't want to add many
hundred lines to the already too big dwarf2read.c. I thought it would
be a logical split to move everything related to the DWARF index to its
own file.
I first tried to move everything that reads and writes DWARF indices to
a separate file, but found that the "read" part is a little bit
entangled with the rest of dwarf2read.c, so the line is hard to draw
about where to split. The write part is quite isolated though, so I
moved this part to a new file, dwarf-index-write.c. Some things are
necessary to both reading and writing indices, so I placed them in
dwarf-index-common.{c,h}. The idea would be to have a
dwarf-index-read.c eventually that would use it too (for now that code
is still in dwarf2read.c).
This required moving some things to a new dwarf2read.h header, so they
can be read by the code that writes the index.
The patch is big in number of lines, but it's all existing code being
moved around. The only changes are that some functions are not static
anymore, a declaration is added in a .h file, and therefore the comment
is moved there.
I built-tested it with a little and big endian target.
This patch is also available on the users/simark/split-dwarf2read
branch.

problem looking up some symbols when they have a linkage name
This patch fixes a known failure in gdb.ada/maint_with_ada.exp
(maintenance check-psymtabs). Another way to witness the same
issue is by considering the following Ada declarations...
type Wrapper is record
A : Integer;
end record;
u00045 : constant Wrapper := (A => 16#060287af#);
pragma Export (C, u00045, "symada__cS");
... which declares a variable name "u00045" but with a linkage
name which is "symada__cS". This variable is a record with one
component, the Ada equivalent of a struct with one field in C.
Trying to print that variable's value currently yields:
(gdb) p /x <symada__cS>
'symada(char, signed)' has unknown type; cast it to its declared type
This indicates that GDB was only able to find the minimal symbol,
but not the full symbol. The expected output is:
(gdb) print /x <symada__cS>
$1 = (a => 0x60287af)
The error message gives a hint about what's happening: We processed
the symbol through gdb_demangle, which in the case of this particular
symbol name, ends up matching the C++ naming scheme. As a result,
the demangler transforms our symbol name into 'symada(char, signed)',
thus breaking Ada lookups.
This patch fixes the issue by first introducing a new language_defn
attribute called la_store_sym_names_in_linkage_form_p, which is a boolean
to be set to true for the few languages that do not want their symbols
to have their names stored in demangled form, and false otherwise.
We then use this language attribute to skip the call to gdb_demangle
for all languages whose la_store_sym_names_in_linkage_form_p is true.
In terms of the selection of languages for which the new attribute
is set to true, the selection errs on the side of preserving the
existing behavior, and only changes the behavior for the languages
where we are certain storing symbol names in demangling form is not
needed. It is conceivable that other languages might be in the same
situation, but I not knowing in detail the symbol name enconding
strategy, I decided to play it safe and let other language maintainers
potentially adjust their language if it makes sense to do so.

Convert observers to C++
This converts observers from using a special source-generating script
to be plain C++. This version of the patch takes advantage of C++11
by using std::function and variadic templates; incorporates Pedro's
patches; and renames the header file to "observable.h" (this change
eliminates the need for a clean rebuild).
Note that Pedro's patches used a template lambda in tui-hooks.c, but
this failed to compile on some buildbot instances (presumably due to
differing C++ versions); I replaced this with an ordinary template
function.
Regression tested on the buildbot.

Add silent Makefile rules
Many projects (e.g. the Linux kernel) and build systems use "silent"
rules, which means that they'll only print a summary of what's being
done instead of printing all the detailed command lines. While chatting
on the #gdb IRC channel, I realized a few people (including me) thought
it would be nice to have it in GDB too.
The idea is that too much text is not useful, the important information
gets lost. If there's only the essential information, it's more likely
to be useful. Most of the time, when I look at the build output, it's
to see how it's progressing. By just printing a brief summary of each
operation, I can easily spot what's currently being compiled and
therefore how the build progresses (with time you know the order in
which files are compiled almost by heart).
As with other projects (Linux, automake-based things, probably others),
it's possible to print the complete command lines by passing V=1 to make
(or any other non-zero value).
I had one hesitation about this: when people report build failures, we
are more likely to miss the full compile command line. We'll probably
sometimes need to ask people to include the build log with "make V=1".
I don't think it's a big downside, if other projects the size of the
Linux kernel can live with it, I'm sure we can too.

gdb: Initial baremetal riscv support
This commit introduces basic support for baremetal RiscV as a GDB
target. This target is currently only tested against the RiscV software
simulator, which is not included as part of this commit. The target has
been tested against the following RiscV variants: rv32im, rv32imc,
rv32imf, rv32imfc, rv64im, rv64imc, rv64imfd, rv64imfdc.
Across these variants we pass on average 34858 tests, and fail 272
tests, which is ~0.8%.
The RiscV has a feature of its ABI where structures with a single
floating point field, a single complex float field, or one float and
one integer field are treated differently for argument passing. The
new test gdb.base/infcall-nested-structs.exp is added to cover this
feature. As passing these structures should work on all targets then
I've made the test as a generic one, even though, for most targets,
there's probably nothing special about any of these cases.
gdb/ChangeLog:
* Makefile.in (ALL_TARGET_OBS): Add riscv-tdep.o
(HFILES_NO_SRCDIR): Add riscv-tdep.h.
(ALLDEPFILES): Add riscv-tdep.c
* configure.tgt: Add riscv support.
* riscv-tdep.c: New file.
* riscv-tdep.h: New file.
* NEWS: Mention new target.
* MAINTAINERS: Add entry for riscv.
gdb/testsuite/ChangeLog:
* gdb.base/infcall-nested-structs.exp: New file.
* gdb.base/infcall-nested-structs.c: New file.
* gdb.base/float.exp: Add riscv support.

Make gdbserver work with filename-only binaries
Simon mentioned on IRC that, after the startup-with-shell feature has
been implemented on gdbserver, it is not possible to specify a
filename-only binary, like:
$ gdbserver :1234 a.out
/bin/bash: line 0: exec: a.out: not found
During startup program exited with code 127.
Exiting
This happens on systems where the current directory "." is not listed
in the PATH environment variable. Although including "." in the PATH
variable is a possible workaround, this can be considered a regression
because before startup-with-shell it was possible to use only the
filename (due to reason that gdbserver used "exec*" directly).
The idea of the patch is to verify if the program path provided by the
user (or by the remote protocol) contains a directory separator
character. If it doesn't, it means we're dealing with a filename-only
binary, so we call "gdb_abspath" to properly expand it and transform
it into a full path. Otherwise, we leave the program path untouched.
This mimicks the behaviour seen on GDB (look at "openp" and
"attach_inferior", for example).
I am also submitting a testcase which exercises the scenario described
above. This test requires gdbserver to be executed in a different CWD
than the original, so I also created a helper function, "with_cwd" (on
testsuite/lib/gdb.exp), which takes care of cd'ing into and out of the
specified dir.
Built and regtested on BuildBot, without regressions.

Workaround a FreeBSD ptrace() bug with clearing thread events.
When multiple threads within a process wish to report STOPPED events
from wait(), the kernel picks one thread event as the thread event to
report. The chosen thread event is retrieved via PT_LWPINFO by
passing the process ID as the request pid. If multiple events are
pending, then the subsequent wait() after resuming a process will
report another STOPPED event after resuming the process to handle the
next thread event and so on.
A single thread event is cleared as a side effect of resuming the
process with PT_CONTINUE, PT_STEP, etc. In older kernels, however,
the request pid was used to select which thread's event was cleared
rather than always clearing the event that was just reported. To
avoid clearing the event of the wrong LWP, always pass the process ID
instead of an LWP ID to PT_CONTINUE or PT_SYSCALL.
In the case of stepping, the process ID cannot be used with PT_STEP
since it would step the thread that reported an event which may not be
the thread indicated by PTID. For stepping, use PT_SETSTEP to enable
stepping on the desired thread before resuming the process via
PT_CONTINUE instead of using PT_STEP.
This manifested as a failure in the
gdb.threads/continue-pending-status.exp test. Specifically, if thread
2 reported a breakpoint and the test thus switched to thread 3 before
continuing, thread 3's event (if any) was discarded and thread 2's
breakpoint remained pending and was reported a second time as a
duplicate event. As a result, the PC was decremented twice for the
same breakpoint resulting in an illegal instruction fault on x86.

MIPS: Don't use a 32-bit BFD architecture with a 64-bit ABI
Select `bfd_mach_mips4000', which corresponds to the MIPS III ISA, the
earlies with 64-bit support, whenever a 32-bit BFD architecture has been
chosen to use with a 64-bit ABI. The situation can happen in a few
cases:
1. When the user has used `set architecture' or `set mips abi' commands
to override automatic selection and then starts a debug session by
requesting to run, attach or connect to a target.
2. In native debugging when reattaching to a previously debugged process
where the program to be debugged has been since discarded, as
observed with:
FAIL: gdb.base/attach.exp: attach2, with no file (GDB internal error)
in n32 and n64 regression testing.
3. In remote debugging with a non-XML debug stub when discarding the
program to be debugged while connected to the remote target, as
observed with:
FAIL: gdb.base/break-unload-file.exp: cmdline: always-inserted on: break: file (GDB internal error)
in n32 and n64 regression testing.
In the latter two cases the ABI, quite rightfully, is retained while the
program to be debugged is discarded. This is because in that case the
ABI previously determined is carried over along with `gdbarch' in use,
which is retained. The BFD architecture is however discarded and the
default then applies, because it is not attached to `gdbarch'.
In all these cases we trip with an internal error message as follows:
.../gdb/mips-tdep.c:766: internal-error: bad register size
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) n
This is a bug, please report it. For instructions, see:
<http://www.gnu.org/software/gdb/bugs/>.
coming from `mips_pseudo_register_read', because the raw register width
inferred from the BFD architecture turns out to be 4 for the general
registers while the cooked register width inferred from the ABI in
effect is 8.
We do not hit this internal error in remote debugging with an XML debug
stub, because in that case raw register width information is passed by
the stub along with the XML target description.
Ultimately I think we ought to make the BFD architecture sticky like the
ABI, however in the interim this simple fix will do, removing the error
across all three cases. The case where the user has used `set mips abi'
or `set architecture' commands has to be handled anyway, and although a
more sophisticated solution could be envisaged, such as reporting an
error with the respective `set' command, I think this is too much of a
corner case to bother.

Convert Rust to use discriminated unions
A Rust enum is, essentially, a discriminated union. Currently the
Rust language support handles Rust enums locally, in rust-lang.c.
However, because I am changing the Rust compiler to use
DW_TAG_variant* to represent enums, it seemed better to have a single
internal representation for Rust enums in gdb.
This patch implements this idea by moving the current Rust enum
handling code to dwarf2read. This allows the simplification of some
parts of rust-lang.c as well.

Re-write partial_die_info allocation in load_partial_dies
load_partial_dies has a "while (1)" loop to visit each die, and create
partial_die_info if needed in each iteration, like this,
part_die = XOBNEW (&cu->comp_unit_obstack, struct partial_die_info);
while (1)
{
if (foo1) continue;
if (foo2) continue;
read_partial_die (, , part_die, ,);
....
part_die = XOBNEW (&cu->comp_unit_obstack, struct partial_die_info);
};
the code was written in a way that spaces are allocated on necessary on
cu->comp_unit_obstack. I want to class-fy partial_die_info, but
partial_die_info ctor can't follow XOBNEW immediately, so this patch
rewrite this loop to:
while (1)
{
if (foo1) continue;
if (foo2) continue;
struct partial_die_info pdi;
read_partial_die (, , &pdi, ,);
part_die = XOBNEW (&cu->comp_unit_obstack, struct partial_die_info);
memcpy (part_die, &pdi, sizeof (pdi));
};
we create a local variable pdi, if we need it, call XOBNEW, and copy.
This also reduce one XOBNEW call. I measured the number of XOBNEW call in
load_partial_dies when gdb reads dwarf2read.o, without this patch, it is
18827, and with this patch, it is 18826.

dwarf: Make sect_offset 64-bits
Does anybody have an opinion about this? It would be nice to unbreak
the "default" build with clang (i.e. without passing special -Wno-error=
flags).
Here's a version rebased on today's master.

ka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare]
if (to_underlying (per_cu.sect_off) >= (static_cast<uint64_t> (1) << 32))
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The code in question checks if there is any offset exceeding 32 bits,
and therefore if we need to use the 64-bit DWARF format when writing the
.debug_names section. The type we use currently to represent section
offsets is an unsigned int (32-bits), which means a value of this type
will never exceed 32 bits, hence the errors above.
There are many signs that we want to support 64-bits DWARF (although I
haven't tested), such as:
- We correctly read initial length fields (read_initial_length)
- We take that into account when reading offsets (read_offset_1)
- The check_dwarf64_offsets function
However, I don't see how it can work if sect_offset is a 32-bits type.
Every time we record a section offset, we risk truncating the value.
And if a file uses the 64-bit DWARF format, it's most likely because
there are such offset values that overflow 32 bits.
Because of this, I think the way forward is to change sect_offset to be
a uint64_t. It will be able to represent any offset, regardless of the
bitness of the DWARF info.
This patch was regtested on the buildbot.

No longer create readonly regcache
Nowadays, we create a readonly regcache in get_return_value, and pass it
to gdbarch_return_value to get the return value. In theory, we can pass a
readable_regcache instance and get the return value, because we don't need
to modify the regcache. Unfortunately, gdbarch_return_value is designed
to multiplex regcache, according to READBUF and WRITEBUF.
# If READBUF is not NULL, extract the return value and save it in this
# buffer.
#
# If WRITEBUF is not NULL, it contains a return value which will be
# stored into the appropriate register.
In fact, gdbarch_return_value should be split to three functions, 1) only
return return_value_convention, 2) pass regcache_readonly and readbuf, 3)
pass regcache and writebuf. These changes are out of the scope of this
patch series, so I pass regcache to gdbarch_return_value even for read,
and trust each gdbarch backend doesn't modify regcache.

Replace regcache::dump with class register_dump
Nowadays, we need to dump registers contents from "readwrite" regcache and
"readonly" regcache,
if (target_has_registers)
get_current_regcache ()->dump (out, what_to_dump);
else
{
/* For the benefit of "maint print registers" & co when
debugging an executable, allow dumping a regcache even when
there is no thread selected / no registers. */
regcache dummy_regs (target_gdbarch ());
dummy_regs.dump (out, what_to_dump);
}
since we'll have two different types/classes for "readwrite" regcache and
"readonly" regcache, we have to move dump method to their parent class,
reg_buffer. However, the functionality of "dump" looks unnecessary to
reg_buffer (because some dump modes like regcache_dump_none,
regcache_dump_remote and regcache_dump_groups don't need reg_buffer at
all, they need gdbarch to do the dump), so I decide to move "dump" into a
separate classes, and each sub-class is about each mode of dump.

Class detached_regcache
jit.c uses the regcache in a slightly different way, the regcache dosen't
write through to target, but it has read and write methods. If I apply
regcache in record-full.c, it has the similar use pattern. This patch
adds a new class detached_regcache, a register buffer, but can be
read and written.
Since jit.c doesn't want to write registers through to target, it uses
regcache as a readonly regcache (because only readonly regcache
disconnects from the target), but it adds a hole in regcache
(raw_set_cached_value) in order to modify a readonly regcache. This patch
fixes this hole completely.
regcache inherits detached_regcache, and detached_regcache inherits
readable_regcache. The ideal design is that both detached_regcache and
readable_regcache inherit reg_buffer, and regcache inherit
detached_regcache and regcache_read (virtual inheritance). I concern
about the performance overhead of virtual inheritance, so I don't do it in
the patch.

Fix GDB crash after Quit thrown from unwinder sniffer
I ran into a GDB crash in gdb.base/bp-cmds-continue-ctrl-c.exp in my
multi-target branch, which turns out exposed a bug that exists in
master too.
That testcase has a breakpoint with a "continue" command associated.
Then the breakpoint is constantly being hit. At the same time, the
testcase is continualy interrupting the program with Ctrl-C, and
re-resuming it, in a loop.
Running that testcase manually under Valgrind, after a few sequences
of 'Ctrl-C' + 'continue', I got:
Breakpoint 1, Quit

Above, when we get to compute_frame_id, fi->unwind is non-NULL,
meaning, we found an unwinder, in this case the Python unwinder, but
somehow, fi->prologue_cache is left NULL. pyuw_this_id then crashes
because it assumes fi->prologue_cache is non-NULL:
static void
pyuw_this_id (struct frame_info *this_frame, void **cache_ptr,
struct frame_id *this_id)
{
*this_id = ((cached_frame_info *) *cache_ptr)->frame_id;
^^^^^^^^^^
'*cache_ptr' here is 'fi->prologue_cache'.
There's a quit() call in pyuw_sniffer that I believe is the one that
sometimes triggers the crash above. The crash can be reproduced
easily with this hack to force a quit out of the python unwinder:
--- a/gdb/python/py-unwind.c
+++ b/gdb/python/py-unwind.c
@@ -497,6 +497,8 @@ pyuw_sniffer (const struct frame_unwind *self, struct frame_info *this_frame,
struct gdbarch *gdbarch = (struct gdbarch *) (self->unwind_data);
cached_frame_info *cached_frame;
+ quit ();
+
gdbpy_enter enter_py (gdbarch, current_language);
TRACE_PY_UNWIND (3, "%s (SP=%s, PC=%s)\n", __FUNCTION__,
After that quit is thrown, any subsequent operation that involves
unwinding results in GDB crashing with SIGSEGV like above.
The problem is that this commit:

Subject: Remove cleanup from frame_prepare_for_sniffer
missed that we need to call frame_cleanup_after_sniffer before
rethrowing the exception too.
Without the fix, the "bt" added to
gdb.base/bp-cmds-continue-ctrl-c.exp in this commit makes GDB crash:

Change openp et al to use a unique_xmalloc_ptr
This changes openp, source_full_path_of, and find_and_open_source to
take a unique_xmalloc_ptr, rather than a char*, as an outgoing
argument type. This simplifies the API, ownership-wise, and allows
for the removal of some cleanups.

Move some declarations to source.h
I noticed a few declarations in defs.h that really could be put into
source.h. I think it's generally preferable to something out of
defs.h unless it is needed by most of the files in gdb.

gdb: Remove cleanup from dw2_do_instantiate_symtab

There's actually a series of three issues reported, but it turns out
they're all related, so we can consider on the first one.
The invalid read is triggered from a destructor which is being invoked
as part of a stack unwind after throwing an error. At the time the
error is thrown, the stack looks like this:

The problem is that in `process_die` (frames 14 and 16) we create a
`process_die_scope` object, that takes a copy of the `struct
dwarf2_cu *` passed into the frame. The destructor of the
`process_die_scope` dereferences the stored pointer. This wouldn't be
an issue, except...
... in dw2_do_instantiate_symtab (frame 19) a clean up was registered that
clears the dwarf2_queue in case of an error. Part of this clean up
involves deleting the `struct dwarf2_cu`s referenced from the queue..
The problem then, is that cleanups are processed at the site of the
throw, while, class destructors are invoked as we unwind their frame.
The result is that we process the frame 19 cleanup (and delete the
struct dwarf2_cu) before we process the destructors in frames 14 and 16.
When we do get back to frames 14 and 16 the objects being references
have already been deleted.
The solution is to remove the cleanup from dw2_do_instantiate_symtab, and
instead use a destructor to release the dwarf2_queue instead. With this
patch in place, the valgrind errors are now resolved.
gdb/ChangeLog:
* dwarf2read.c (dwarf2_release_queue): Delete function, move body
into...
(class dwarf2_queue_guard): ...the destructor of this new class.
(dw2_do_instantiate_symtab): Create instance of the new class
dwarf2_queue_guard, remove cleanup.

This patch changes macro_buffer to be a bit more of a C++ class,
adding constructors, a destructor, and some members. Then this is
used to remove various cleanups in macroexp.c.

MI: Allow non-raw varobj evaluation
Make the MI variable object expression evaluation, with the
-var-evaluate-expression command, recursively call pretty printers, to
match the output of normal expression printing.
Consider the following code:
struct Foo { int val; };
struct Wrapper { Foo foo; };
int main() {
Wrapper w;
w.foo.val = 23;
}
and this pretty printer file:
import gdb.printing
class FooPrinter:
def __init__(self, val):
self.val = val
def to_string(self):
return "Foo" + str(self.val["val"])
class WrapperPrinter:
def __init__(self, val):
self.val = val
def to_string(self):
return self.val["foo"]
test_printer = gdb.printing.RegexpCollectionPrettyPrinter("test")
test_printer.add_printer('Foo', '^Foo$', FooPrinter)
test_printer.add_printer('Wrapper', '^Wrapper$', WrapperPrinter)
gdb.printing.register_pretty_printer(None, test_printer)
Setting a breakpoint at the end of the function, we call the following commands:
-enable-pretty-printing
^done
-var-create var_w @ w
^done,name="var_w",numchild="0",value="{val = 23}",type="Wrapper",dynamic="1",has_more="0"
-var-create var_w_foo @ w.foo
^done,name="var_w_foo",numchild="0",value="Foo23",type="Foo",dynamic="1",has_more="0"
-var-evaluate-expression var_w
^done,value="{val = 23}"
-var-evaluate-expression var_w_foo
^done,value="Foo23"
-data-evaluate-expression w
^done,value="Foo23"
-data-evaluate-expression w.foo
^done,value="Foo23"
So, in the -var-evaluate-expression var_w case, we print the "raw" value
of w.foo, while in the -data-evaluate-expression w case, we print the
pretty printed w.foo value. After this patch, all of the above print
"Foo23".

internal-error using '@' (repeat) operator on array of dynamic objects
Using the following Ada declarations (the same as in
gdb.ada/dyn_stride.exp)...
subtype Small_Type is Integer range L .. U;
type Record_Type (I : Small_Type := L) is record
S : String (1 .. I);
end record;
type Array_Type is array (Integer range <>) of Record_Type;
A1 : Array_Type :=
(1 => (I => U, S => (others => ASCII.NUL)),
2 => (I => 1, S => "A"),
3 => (I => 2, S => "AB"));
... where "L" and "U" are variables, trying to apply the repeat
operator to "A1(1)" yields to an internal error:
| (gdb) print a1(1)@3
| $5 = /[...]/gdbtypes.c:4883: internal-error: type* copy_type(const type*):
| Assertion `TYPE_OBJFILE_OWNED (type)' failed.
What happens first is that the ada-lang module evaluated the "A1(1)"
sub-expression returning a structure where "I" (one of the fields
in that structure) has a type which is dynamic, because it is
a range type whose bounds are not statically known.
Next, we apply the repeat ('@') operator, which is done via
allocate_repeat_value, which creates an array type with the correct
bounds to associate to our value, by calling lookup_array_range_type:
| struct type *
| lookup_array_range_type (struct type *element_type,
| LONGEST low_bound, LONGEST high_bound)
| {
| struct gdbarch *gdbarch = get_type_arch (element_type);
| struct type *index_type = builtin_type (gdbarch)->builtin_int;
| struct type *range_type
| = create_static_range_type (NULL, index_type, low_bound, high_bound);
|
| return create_array_type (NULL, element_type, range_type);
| }
As we can see, this creates an array type whose index type is
always owned by the gdbarch. This is where the problem lies.
Next, we use that type to construct a struct value. That value
then gets passed to the valprint module, which then checks
whether our object is dynamic or not. And because field "I" above
had a dynamic range type, we end up determining by association
that the artificial repeat array itself is also dynamic. So
we attempt to resolve the type, which leads to trying to copying
that type. And because the artifical array created by
lookup_array_range_type has an index which is not objfile-owned,
we trip the assertion.
This patch fixes the issue by enhancing lookup_array_range_type
to create an index type which has the same owner as the element
type.

* gdbtypes.c (lookup_array_range_type): Make sure the array's
index type is objfile-owned if the element type is as well.

* testsuite/gdb.ada/dyn_stride.exp: Add "print a1(1)@3" test.

Per-inferior target_terminal state, fix PR gdb/13211, more
In my multi-target branch I ran into problems with GDB's terminal
handling that exist in master as well, with multi-inferior debugging.
This patch adds a testcase for said problems
(gdb.multi/multi-term-settings.exp), fixes the problems, fixes PR
gdb/13211 as well (and adds a testcase for that too,
gdb.base/interrupt-daemon.exp).
The basis of the problem I ran into is the following. Consider a
scenario where you have:
- inferior 1 - started with "attach", process is running on some
other terminal.
- inferior 2 - started with "run", process is sharing gdb's terminal.
In this scenario, when you stop/resume both inferiors, you want GDB to
save/restore the terminal settings of inferior 2, the one that is
sharing GDB's terminal. I.e., you want inferior 2 to "own" the
terminal (in target_terminal::is_ours/target_terminal::is_inferior
sense).
Unfortunately, that's not what you get currently. Because GDB doesn't
know whether an attached inferior is actually sharing GDB's terminal,
it tries to save/restore its settings anyway, ignoring errors. In
this case, this is pointless, because inferior 1 is running on a
different terminal, but GDB doesn't know better.
And then, because it is only possible to have the terminal settings of
a single inferior be in effect at a time, or make one inferior/pgrp be
the terminal's foreground pgrp (aka, only one inferior can "own" the
terminal, ignoring fork children here), if GDB happens to try to
restore the terminal settings of inferior 1 first, then GDB never
restores the terminal settings of inferior 2.
This patch fixes that and a few things more along the way:
- Moves enum target_terminal::terminal_state out of the
target_terminal class (it's currently private) and makes it a
scoped enum so that it can be easily used elsewhere.
- Replaces the inflow.c:terminal_is_ours boolean with a
target_terminal_state variable. This allows distinguishing is_ours
and is_ours_for_output states. This allows finally making
child_terminal_ours_1 do something with its "output_only"
parameter.
- Makes each inferior have its own copy of the
is_ours/is_ours_for_output/is_inferior state.
- Adds a way for GDB to tell whether the inferior is sharing GDB's
terminal. Works best on Linux and Solaris; the fallback works just
as well as currently.
- With that, we can remove the inf->attach_flag tests from
child_terminal_inferior/child_terminal_ours.
- Currently target_ops.to_ours is responsible for both saving the
current inferior's terminal state, and restoring gdb's state.
Because each inferior has its own terminal state (possibly handled
by different targets in a multi-target world, even), we need to
split the inferior-saving part from the gdb-restoring part. The
patch adds a new target_ops.to_save_inferior target method for
that.
- Adds a new target_terminal::save_inferior() function, so that
sequences like:
scoped_restore_terminal_state save_state;
target_terminal::ours_for_output ();
... restore back inferiors that were
target_terminal_state::is_inferior before back to is_inferior, and
leaves inferiors that were is_ours alone.
- Along the way, this adds a default implementation of
target_pass_ctrlc to inflow.c (for inf-child.c), that handles
passing the Ctrl-C to a process running on GDB's terminal or to
some other process otherwise.
- Similarly, adds a new target default implementation of
target_interrupt, for the "interrupt" command. The current
implementation of this hook in inf-ptrace.c kills the whole process
group, but that's incorrect/undesirable because we may not be
attached to all processes in the process group. And also, it's
incorrect because inferior_process_group() doesn't really return
the inferior's real process group id if the inferior is not a
process group leader... This is the cause of PR gdb/13211 [1],
which this patch fixes. While at it, that target method's "ptid"
parameter is eliminated, because it's not really used.
- A new test is included that exercises and fixes PR gdb/13211, and
also fixes a GDB issue reported on stackoverflow that I ran into
while working on this [2]. The problem is similar to PR gdb/13211,
except that it also triggers with Ctrl-C. When debugging a daemon
(i.e., a process that disconnects from the controlling terminal and
is not a process group leader, then Ctrl-C doesn't work, you just
can't interrupt the inferior at all, resulting in a hung debug
session. The problem is that since the inferior is no longer
associated with gdb's session / controlling terminal, then trying
to put the inferior in the foreground fails. And so Ctrl-C never
reaches the inferior directly. pass_signal is only used when the
inferior is attached, but that is not the case here. This is fixed
by the new child_pass_ctrlc. Without the fix, the new
interrupt-daemon.exp testcase fails with timeout waiting for a
SIGINT that never arrives.

[2] GDB not reacting Ctrl-C when after fork() and setsid()
https://stackoverflow.com/questions/46101292/gdb-not-reacting-ctrl-c-when-after-fork-and-setsid
Note this patch does _not_ fix:
- PR gdb/14559 - The 'interrupt' command does not work if sigwait is in use
https://sourceware.org/bugzilla/show_bug.cgi?id=14559
- PR gdb/9425 - When using "sigwait" GDB doesn't trap SIGINT. Ctrl+C terminates program when should break gdb.
https://sourceware.org/bugzilla/show_bug.cgi?id=9425
The only way to fix that that I know of (without changing the kernel)
is to make GDB put inferiors in a separate session (create a
pseudo-tty master/slave pair, make the inferior run with the slave as
its terminal, and have gdb pump output/input on the master end).

Don't call "detach_inferior" on "remote_follow_fork"
This patch fixes a regression that has been introduced by:
commit bc09b0c14fb713a9aec25e09b78499f3bc2441b5
Date: Fri Jan 19 11:48:11 2018 -0500
Make linux_nat_detach/thread_db_detach use the inferior parameter
It is possible to trigger this failure with gdb.base/foll-fork.exp (in
which case a bunch of ERROR's will be printed), but one can also use
the test below.
Consider the following example program:
#include <unistd.h>
int
main (int argc, char *argv[])
{
fork ();
return 0;
}
When running it under gdbserver:
# ./gdb/gdbserver/gdbserver --multi --once :2345
And debugging it under GDB, we see a segmentation fault:
# ./gdb/gdb -q -batch -ex 'set remote exec-file ./a.out' -ex 'tar extended-remote :2345' -ex r ./a.out
Starting program:
...
[Detaching after fork from child process 16102.]
Segmentation fault (core dumped)
The problem happens on inferior.c:detach_inferior:
void
detach_inferior (inferior *inf)
{
/* Save the pid, since exit_inferior_1 will reset it. */
int pid = inf->pid;
^^^^^^^^^
exit_inferior_1 (inf, 0);
if (print_inferior_events)
printf_unfiltered (_("[Inferior %d detached]\n"), pid);
}
When this code is called from remote.c:remote_follow_fork, the PID is
valid but there is no 'inferior' associated with it, which means that
'inf == NULL'.
The proper fix here is to not call "detach_inferior" when doing remote
follow-fork, because we don't have an inferior to detach on the host
side.
Before bc09b0c1, that call was already a nop (exit_inferior_1 bails
out early if you pass it a NULL inferior), except that it printed
"Inferior PID detached" when "set print inferior-events" is on. Since
native debugging doesn't call detach_inferior in this case, removing
the call from remote aligns remote debugging output with native
debugging output further.
This has been regtested using BuildBot and no regressions were found.

Fix GCC PR83906 - [8 Regression] Random FAIL: libstdc++-prettyprinters/80276.cc whatis p4
GCC PR83906 [1] is about a GCC/libstdc++ GDB/Python type printer
testcase failing randomly, as shown by running (in libstdc++'s
testsuite):
make check RUNTESTFLAGS=prettyprinters.exp=80276.cc
in a loop. Sometimes you get this:
FAIL: libstdc++-prettyprinters/80276.cc whatis p4
I.e., this:
type = std::unique_ptr<std::vector<std::unique_ptr<std::list<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >>[]>>[99]>
instead of this:
type = std::unique_ptr<std::vector<std::unique_ptr<std::list<std::string>[]>>[99]>
Jonathan Wakely tracked it on the printer side to this bit in
libstdc++'s type printer:
if self.type_obj == type_obj:
return strip_inline_namespaces(self.name)
This assumes the two types resolve to the same gdb.Type but some times
the comparison unexpectedly fails.
Running the testcase manually under Valgrind finds the problem in GDB:

That "bcmp" call is really a memcmp call in check_types_equal. The
problem is that gdb is memcmp'ing two objects that are equal in value:
(top-gdb) p *TYPE_RANGE_DATA (type1)
$1 = {low = {kind = PROP_CONST, data = {const_val = 0, baton = 0x0}}, high = {kind = PROP_CONST, data = {const_val = 15, baton = 0xf}}, flag_upper_bound_is_count = 0,
flag_bound_evaluated = 0}
(top-gdb) p *TYPE_RANGE_DATA (type2)
$2 = {low = {kind = PROP_CONST, data = {const_val = 0, baton = 0x0}}, high = {kind = PROP_CONST, data = {const_val = 15, baton = 0xf}}, flag_upper_bound_is_count = 0,
flag_bound_evaluated = 0}
but differ in padding. Notice the 4-byte hole:
(top-gdb) ptype /o range_bounds
/* offset | size */ type = struct range_bounds {
/* 0 | 16 */ struct dynamic_prop {
/* 0 | 4 */ dynamic_prop_kind kind;
/* XXX 4-byte hole */
/* 8 | 8 */ union dynamic_prop_data {
/* 8 */ LONGEST const_val;
/* 8 */ void *baton;
/* total size (bytes): 8 */
} data;
which is filled with garbage:

(top-gdb) p memcmp (TYPE_RANGE_DATA (type1), TYPE_RANGE_DATA (type2), sizeof (*TYPE_RANGE_DATA (type1)))
$3 = -187
In some cases objects of type range_bounds are memset when allocated,
but then their dynamic_prop low/high fields are copied over from some
template dynamic_prop object that wasn't memset. E.g.,
create_static_range_type's low/high locals are left with garbage in
the padding, and then that padding is copied over to the range_bounds
object's low/high fields.
At first, I considered making sure to always memset range_bounds
objects, thinking that maybe type objects are being put in some bcache
instance somewhere. But then I hacked bcache/bcache_full to poison
non-pod types, and made dynamic_prop a non-pod, and GDB still
compiled.
So given that, it seems safest to not assume padding will always be
memset, and instead treat them as regular value types, implementing
(in)equality operators and using those instead of memcmp.
This fixes the random FAILs in GCC's testcase.

s390: Split up s390-linux-tdep.c into two files
Currently all target dependent code for s390 is in one file,
s390-linux-tdep.c. This includes code general for the architecture as
well as code specific for uses in GNU/Linux (user space). Up until now
this was OK as GNU/Linux was the only supported OS. In preparation to
support the new Linux kernel 'OS' split up the existing s390 code into a
general s390-tdep and a GNU/Linux-specific s390-linux-tdep.
Note: The record-replay feature will be moved in a separate patch. This
is simply due to the fact that the combined patch would be too large for
the mailing list. This requires setting the process_record hook during
OSABI init to keep the code bisectable. The patch moving record-replay
cleans up this hack.

Fix segfault with 'set print object on' + 'whatis <struct>' & co
Compiling GDB with a recent GCC exposes a problem:
../../gdb/typeprint.c: In function 'void whatis_exp(const char*, int)':
../../gdb/typeprint.c:515:12: warning: 'val' may be used uninitialized in this function [-Wmaybe-uninitialized]
real_type = value_rtti_type (val, &full, &top, &using_enc);
~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The warning is correct. There are indeed code paths that use
uninitialized 'val', leading to crashes. Inside the
value_rtti_indirect_type/value_rtti_type calls here in whatis_exp:
if (opts.objectprint)
{
if (((TYPE_CODE (type) == TYPE_CODE_PTR) || TYPE_IS_REFERENCE (type))
&& (TYPE_CODE (TYPE_TARGET_TYPE (type)) == TYPE_CODE_STRUCT))
real_type = value_rtti_indirect_type (val, &full, &top, &using_enc);
else if (TYPE_CODE (type) == TYPE_CODE_STRUCT)
real_type = value_rtti_type (val, &full, &top, &using_enc);
}
We reach those calls above with "set print object on", and then with
any of:
(gdb) whatis struct some_structure_type
(gdb) whatis struct some_structure_type *
(gdb) whatis struct some_structure_type &
because "whatis" with a type argument enters this branch:
/* The behavior of "whatis" depends on whether the user
expression names a type directly, or a language expression
(including variable names). If the former, then "whatis"
strips one level of typedefs, only. If an expression,
"whatis" prints the type of the expression without stripping
any typedef level. "ptype" always strips all levels of
typedefs. */
if (show == -1 && expr->elts[0].opcode == OP_TYPE)
{
which does not initialize VAL. Trying the above triggers crashes like
this:
(gdb) set print object on
(gdb) whatis some_structure_type
Thread 1 "gdb" received signal SIGSEGV, Segmentation fault.
0x00000000005dda90 in check_typedef (type=0x6120736573756170) at src/gdb/gdbtypes.c:2388
2388 int instance_flags = TYPE_INSTANCE_FLAGS (type);
...
This is a regression caused by a recent-ish refactoring of the code on
'whatis_exp', introduced by:
commit c973d0aa4a2c737ab527ae44a617f1c357e07364
Date: Mon Aug 21 11:34:32 2017 +0100
Fix type casts losing typedefs and reimplement "whatis" typedef stripping
Fix this by setting VAL to NULL in the "whatis TYPE" case, and
skipping fetching the dynamic type if there's no value to fetch it
from.
New tests included.

wrong line number in breakpoint location
Consider the following situation, where we have one file containing...
$ cat -n body.inc
1 i = i + 1;
... we include that file from some code, like so:
$ cat -n cat -n small.c
[...]
17 int
18 next (int i)
19 {
20 #include "body.inc"
21 return i;
22 }
When trying to insert a breakpoint on line 18, for instance:
(gdb) b small.c:18
Breakpoint 1 at 0x40049f: file body.inc, line 18.
^^
||
Here, the issue is that GDB reports the breakpoint to be in file
body.inc, which is true, but with the line number that corresponding
to the user-requested location, which is not correct.
Although the simple reproducer may look slightly artificial,
the above is simply one way to reproduce the same issue observed
when trying to insert a breakpoint on a function provided in
a .h files and then subsequently inlined in a C file.
What happens is the following:
1. We resolve the small.c:18 linespec into a symtab_and_line which
has "small.c" and 18 as the symtab and line number.
2. Next, we call skip_prologue_sal, which calculates the PC
past the prologue, and updates the symtab_and_line: PC,
but also symtab (now body.inc) and the new line (now 1).
3. However, right after that, we do:
/* Make sure the line matches the request, not what was
found. */
intermediate_results.sals[i].line = val.line;
We should either restore both symtab and line, or leave the actual
line to match the actual symtab. This patch chose the latter.
This introduces a few changes in a few tests, which required some
updates, but looking at those change, I believe them to be expected.
gdb/ChangeLog:
* linespec.c (create_sals_line_offset): Remove code that preserved
the symtab_and_line's line number.
gdb/testsuite/ChangeLog:
* gdb.base/break-include.c, gdb.base/break-include.inc,

gdb: PR mi/20395: Fix -var-update for registers in frames 1 and up
This patch fixes a problem with using the MI -var-update command
to access the values of registers in frames other than the current
frame. The patch includes a test that demonstrates the problem:
* run so there are several frames on the stack
* create a fixed varobj for $pc in each frame, #'s 1 and above
* step one instruction, to modify the value of $pc
* call -var-update for each of the previously created varobjs
to verify that they are not reported as having changed.
Without the patch, the -var-update command reported that $pc for all
frames 1 and above had changed to the value of $pc in frame 0.
A varobj is created as either fixed, the expression is evaluated within
the context of a specific frame, or floating, the expression is
evaluated within the current frame, whatever that may be.
When a varobj is created by -var-create we set two fields of the varobj
to track the context in which the varobj was created, these two fields
are varobj->root->frame and var->root->valid_block.
If a varobj is of type fixed, then, when we subsequently try to
reevaluate the expression associated with the varobj we must determine
if the original frame (and block) is still available, if it is not then
the varobj can no longer be evaluated.
The problem is that for register expressions varobj->root->valid_block
is not set correctly. This block tracking is done using the global
'innermost_block' which is set in the various parser files (for example
c-exp.y). However, this is not set for register expressions.
The fix then seems like it should be to just update the innermost block
when parsing register expressions, however, that solution causes several
test regressions.
The problem is that in some cases we rely on the expression parsing
code not updating the innermost block for registers, one example is
when we parse the expression for a 'display' command. The display
commands treats registers like floating varobjs, but symbols are
treated like fixed varobjs. So 'display $reg_name' will always show
the value of '$reg_name' even as the user moves from frame to frame,
while 'display my_variable' will only show 'my_variable' while it is
in the current frame and/or block, when the user moves to a new frame
and/or block (even one with a different 'my_variable' in) then the
display of 'my_variable' stops. For the case of 'display', without
the option to force fixed or floating expressions, the current
behaviour is probably the best choice. For the varobj system though,
we can choose between floating and fixed, and we should try to make
this work for registers.
There's only one existing test case that needs to be updated, in that
test a fixed varobj is created using a register, the MI output now
include the thread-id in which the varobj should be evaluated, which I
believe is correct behaviour. I also added a new floating test case
into the same test script, however, right now this also includes the
thread-id in the expected output, which I believe is an existing gdb
bug, which I plan to fix next.
Tested on x86_64 Linux native and native-gdbserver, no regressions.

Make linux_nat_detach/thread_db_detach use the inferior parameter
This patch makes these two functions actually use the inferior parameter
added by the previous patch, instead of reading inferior_ptid. I chose
these two, because they are the one actually used when I detach on my
GNU/Linux system, so they were easy to test.
I took the opportunity to pass the inferior being detached to
inf_ptrace_detach_success, so it could use it too. From there, it made
sense to add an overload of detach_inferior that takes the inferior
directly rather than the pid, to avoid having to pass inf->pid only for
the callee to look up the inferior structure by pid.
gdb/ChangeLog:
* inf-ptrace.c (inf_ptrace_detach): Adjust call to
inf_ptrace_detach_success.
(inf_ptrace_detach_success): Add inferior parameter, use it
instead of inferior_ptid, pass it to detach_inferior.

Remove args from target detach
I was looking into adding a parameter to target_detach, and was
wondering what the args parameter was. It seems like in the distant
past, it was possible to specify a signal number when detaching. That
signal was injected in the process before it was detached. There is an
example of code handling this in linux_nat_detach. With today's GDB, I
can't get this to work. Doing "detach 15" (15 == SIGTERM) doesn't work,
because detach is a prefix command and doesn't recognize the sub-command
15. Doing "detach inferiors 15" doesn't work because it expects a list
of inferior id to detach. Therefore, I don't think there's a way of
invoking detach_command with a non-NULL args. I also didn't find any
documentation related to this feature.
I assume that this feature stopped working when detach was made a prefix
command, which is in f73adfeb8bae36885e6ea248d12223ab0d5eb9cb (sorry,
there's no commit title) from 2006. Given that this feature was broken
for such a long time and we haven't heard anything (AFAIK, I did not
find any related bug), I think it's safe to remove it, as well as the
args parameter to target_detach. If someone wants to re-introduce it, I
would suggest rethinking the user interface, and in particular would
suggest using signal name instead of numbers.
I tried to fix all the impacted code, but I might have forgotten some
spots. It shouldn't be hard to fix if that's the case. I also couldn't
build-test everything I changed, especially the nto and solaris stuff.

Fix gdb segv when objfile can't be opened
This fixes PR 16577.
This patch changes gdb_bfd_map_section to issue a warning rather than an error
if it is unable to read the object file, and sets the size of the section/frame
that it attempted to read to 0 on error.
The description of gdb_bfd_map_section states that it will try to read or map
the contents of the section SECT, and if successful, the section data is
returned and *SIZE is set to the size of the section data. This function was
throwing an error and leaving *SIZE as-is. Setting the section size to 0
indicates to dwarf2_build_frame_info that there is no data to read, otherwise
it will try to read from an invalid frame pointer.
Changing the error to a warning allows this to be handled gracefully.
Additionally, the error was clobbering the breakpoint output indicating the
current frame (function name, arguments, source file, and line number). E.g.
Thread 3 "foo" hit Breakpoint 1, BFD: reopening /tmp/jna-1013829440/jna2973250704389291330.tmp: No such file or directory
BFD: reopening /tmp/jna-1013829440/jna2973250704389291330.tmp: No such file or directory
(gdb)
While the "BFD: reopening ..." messages will still appear interspersed in the
breakpoint output, the current frame info is now displayed:
Thread 3 "foo" hit Breakpoint 1, BFD: reopening /tmp/jna-1013829440/jna1875755897659885075.tmp: No such file or directory

configure: Fix test for fs_base/gs_base in <sys/user.h>
Make <sys/types.h> be included prior to including <sys/user.h>.
glibc versions older than 2.14 use __uintNN_t types within certain
structures defined in <sys/user.h> probably assuming these types are
defined prior to including the header. This results in the following
`configure` feature test compilation error that makes it think that
`struct user_regs_struct` doesn't have `fs_base`/`gs_base` fields,
althouh it does.

Recent glibc versions don't use typedef'ed int types in <sys/user.h>,
thus allowing it to be included as is
(glibc commit d79a9c949c84e7f0ba33e87447c47af833e9f11a).
However there're still some distros alive that use older glibc,
for instance, RHEL/CentOS 6 package glibc 2.12.
Also affects PR gdb/21559:
../../gdb/regcache.c:1087: internal-error: void regcache_raw_supply(regcache, int, const void): Assertion `regnum >= 0 && regnum < regcache->descr->nr_raw_registers' failed.
As noted by Andrew Paprocki, who submitted the PR
(https://sourceware.org/bugzilla/show_bug.cgi?id=21559#c3):
> It should be noted that modifying `configure` to force on
> `HAVE_STRUCT_USER_REGS_STRUCT_FS_BASE` and
> `HAVE_STRUCT_USER_REGS_STRUCT_GS_BASE` fixes this issue. For some
> reason the `configure` tests for `fs_base` and `gs_base` fail
> even though `sys/user.h` on RHEL5 has the fields defined in
> `user_regs_struct`.
Note that this patch does NOT fix the root cause of PR gdb/21559,
although now that `configure` properly detects the presence of the
fields and sets HAVE_XXX accordingly, the execution takes another
path, which doesn't lead to the assertion failure in question.

Fix GDB hang with remote after error from resume
Since this commit --
Fix PR18360 - internal error when using "interrupt -a"
(https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=c65d6b55)
-- the testsuite shows long delays on s390 with native-gdbserver when
executing certain tests, such as watchpoints.exp. These hangs have been
discussed before in the context of buildbot problems, see here:
https://sourceware.org/ml/gdb-patches/2017-12/msg00413.html
The problem can easily be triggered by stopping on a breakpoint, then
setting impossible watchpoints, and finally doing "continue". Then, after
having set the step-over state (in keep_going_pass_signal in infrun.c),
GDB tries to insert breakpoints and watchpoints into the inferior. This
fails, and the "continue" command is aborted. But the step-over state is
not cleared in this case, which causes future step-over attempts to be
skipped since GDB thinks that "we already have an in-line step-over
operation ongoing" (see start_step_over in infrun.c). Thus the next
"continue" just goes on to wait for events from the remote, which will
never occur.
The problem can also be reproduced on amd64 with native-gdbserver, using
the following change to watchpoints.exp:
-- >8 --
--- a/gdb/testsuite/gdb.base/watchpoints.exp
+++ b/gdb/testsuite/gdb.base/watchpoints.exp
@@ -61,2 +61,3 @@ with_test_prefix "before inferior start" {
gdb_test "watch ival3" ".*" ""
+ gdb_test "watch *(char \[256\] *) main"
-- >8 --
To fix the hang, this patch clears the step-over info when
insert_breakpoints has failed. Of course, with native-gdbserver the
watchpoints.exp test case still causes many FAILs on s390, because
gdbserver does not support watchpoints for that target. This is a
separate issue.

gdb.base/breakpoint-in-ro-region.exp regression on sss targets (PR gdb/22583)
As Maciej reported at
<https://sourceware.org/ml/gdb-patches/2017-12/msg00212.html>, this
commit:
commit d930703d68ae160ddfe8ebe5fdcf416fb6090e1e
Date: Thu Nov 16 18:44:43 2017 +0000
Subject: Don't ever Quit out of resume
caused regressions on software single-set targets, specifically:
FAIL: gdb.base/breakpoint-in-ro-region.exp: always-inserted off: auto-hw off: single-step breakpoint is not left behind
FAIL: gdb.base/breakpoint-in-ro-region.exp: always-inserted off: auto-hw on: single-step breakpoint is not left behind
FAIL: gdb.base/breakpoint-in-ro-region.exp: always-inserted on: auto-hw off: step in ro region (cannot insert hw break)
FAIL: gdb.base/breakpoint-in-ro-region.exp: always-inserted on: auto-hw off: single-step breakpoint is not left behind
FAIL: gdb.base/breakpoint-in-ro-region.exp: always-inserted on: auto-hw on: single-step breakpoint is not left behind
and indeed detailed logs indicate a breakpoint is left lingering, e.g.:
(gdb) PASS: gdb.base/breakpoint-in-ro-region.exp: always-inserted off: auto-hw off: step in ro region (cannot insert sw break)
maint info breakpoints 0
Num Type Disp Enb Address What
0 sw single-step keep y 0x00400774 in main at [...]/gdb/testsuite/gdb.base/breakpoint-in-ro-region.c:24 inf 1 thread 1
stop only in thread 1
(gdb) FAIL: gdb.base/breakpoint-in-ro-region.exp: always-inserted off: auto-hw off: single-step breakpoint is not left behind
vs:
(gdb) PASS: gdb.base/breakpoint-in-ro-region.exp: always-inserted off: auto-hw off: step in ro region (cannot insert sw break)
maint info breakpoints 0
No breakpoint or watchpoint matching '0'.
(gdb) PASS: gdb.base/breakpoint-in-ro-region.exp: always-inserted off: auto-hw off: single-step breakpoint is not left behind
as at commit d930703d68ae^.
Before commit d930703d68ae, we had a cleanup installed in 'resume'
that would delete single-step breakpoints on error:
/* Resuming. */
/* Things to clean up if we QUIT out of resume (). */
static void
resume_cleanups (void *ignore)
{
if (!ptid_equal (inferior_ptid, null_ptid))
delete_single_step_breakpoints (inferior_thread ());
normal_stop ();
}
That whole function was removed by d930703d68ae mainly to eliminate
the normal_stop call:
~~~~
Note that the exception called from within resume ends up calling
normal_stop via resume_cleanups. That's very borked though, because
normal_stop is going to re-handle whatever was the last reported
event, possibly even re-running a hook stop...
~~~~
But as the regression shows, removing resume_cleanups completely went
a bit too far, as the delete_single_step_breakpoints call is still
necessary.
So fix the regression by reinstating the
delete_single_step_breakpoints call on error. However, since we're
trying to eliminate cleanups, restore it in a different form (using
TRY/CATCH).
Tested on x86-64 GNU/Linux both top of master and on top of a series
that implements software single-step on x86.

Fix backwards compatibility with old GDBservers (PR remote/22597)
At <https://sourceware.org/ml/gdb-patches/2017-12/msg00285.html>,
Maciej reported that commit:
commit 5cd63fda035d4ba949e6478406162c4673b3c9ef
Date: Wed Oct 4 18:21:10 2017 +0100
Subject: Fix "Remote 'g' packet reply is too long" problems with multiple inferiors
made GDB stop working with older stubs. Any attempt to continue
execution after the initial connection fails with:
[...]

The problem is:
(gdb) c
Cannot execute this command without a live selected thread.
(gdb) info threads
Id Target Id Frame
1 Thread 14917 0x00007f341cd98ed0 in _start () from /lib64/ld-linux-x86-64.so.2
The current thread <Thread ID 2> has terminated. See `help thread'.
^^^^^^^^^^^
(gdb)
Note, thread _2_. There's really only one thread in the inferior
(it's still at the entry point), but still GDB added a bogus second
thread.
The reason GDB started adding a second thread after 5cd63fda035d is
this hunk:
+ if (event->ptid == null_ptid)
+ {
+ const char *thr = strstr (p1 + 1, ";thread:");
+ if (thr != NULL)
+ event->ptid = read_ptid (thr + strlen (";thread:"),
+ NULL);
+ else
+ event->ptid = magic_null_ptid;
+ }
Note the else branch that falls back to magic_null_ptid. We reach
that when we process the initial stop reply sent back in response to
the the "?" (status) packet early in the connection setup:
Sending packet: $?#3f...Ack
Packet received: T0506:0000000000000000;07:40a510f4fd7f0000;10:d0fe1201577f0000;
And note that that response does not include a ";thread:XXX" part.
This stop reply is processed after listing threads with qfThreadInfo /
qsThreadInfo :
Sending packet: $qfThreadInfo#bb...Ack
Packet received: m3915
Sending packet: $qsThreadInfo#c8...Ack
Packet received: l
meaning, when we process that stop reply, we treat the event as coming
from a thread with ptid == magic_null_ptid, which is not yet in the
thread list, so we add it then:
(top-gdb) p ptid
$1 = {m_pid = 42000, m_lwp = -1, m_tid = 1}

things go downhill from this.
We don't see the problem with current master gdbserver, because that
version always sends the ";thread:" part in the initial stop reply:
Sending packet: $?#3f...Packet received: T0506:0000000000000000;07:a0d4ffffff7f0000;10:d05eddf7ff7f0000;thread:p3cea.3cea;core:3;
Years ago I had added a "--disable-packet=" command line option to
gdbserver which comes in handy for testing this, since the existing
"--disable-packet=Tthread" precisely makes gdbserver not send that
";thread:" part in stop replies. The testcase added by this commit
emulates old gdbserver making use of that.
I've compared a testrun at 5cd63fda035d^ (before regression) with
'current master+patch', against old gdbserver at f8b73d13b7ca^. I
hacked out --once, and "monitor exit" to be able to test. The results
are a bit too unstable to tell accurately, but it looked like there
were no regressions. Maciej confirmed this worked for him as well.
No regressions on master (against master gdbserver).

Ada: make verbatim matcher override other language matchers (PR gdb/22670)
A previous patch fixed verbatim matching in the lookup at the minimal
symbol level, but we should also be finding that same symbol through
the partial/full symtab search.
For example, this is what happens if we use "print" instead of
"break":
(gdb) p <MixedCaseFunc>
$1 = {<text variable, no debug info>} 0x4024dc <MixedCaseFunc>
Before the C++ wildmatching series, GDB knows that MixedCaseFunc is a
function without parameters, and the expression above means calling
it. If you try it before having started the inferior, you'd get the
following (expected) error:
(gdb) print <MixedCaseFunc>
You can't do that without a process to debug.
The main idea behind making the name matcher be determined by the
symbol's language is so that C++ (etc.) wildmatching in linespecs
works even if the current language is not C++, as e.g., when you step
through C or assembly code.
Ada's verbatim matching syntax however ("<...>") isn't quite the same.
It is more a property of the current language than of a particular
symbol's language. We want to support this syntax when debugging an
Ada program, but it's reason of existence is to find non-Ada symbols.
This suggests going back to enabling it depending on current language
instead of language of the symbol being matched.
I'm not entirely happy with the "current_language" reference (though I
think that it's harmless). I think we could try storing the current
language in the lookup_name_info object, and then convert a bunch of
functions more to pass around lookup_name_info objects instead of
"const char *" names. I.e., build the lookup_name_info higher up.
I'm not sure about that, I'll have to think more about it. Maybe
something different will be better. Meanwhile, this gets us going.
I've extended the testcase to also exercise a no-debug-info function,
for extra coverage of the minsyms-only paths.

Support 'info proc' for FreeBSD process core dumps.
- Command line arguments are obtained from the pr_psargs[] array
saved in the NT_PRPSINFO note.
- The 'cwd' and 'exe' values are obtained from the per-process file
descriptor table stored in the NT_PROCSTAT_FILES core note.
- 'mappings' is implemented by walking the array of VM map entries
stored in the NT_PROCSTAT_VMMAP core note.
- 'status' output is generated by outputting fields from
the first structure stored in the NT_PROCSTAT_PROC core note.
- 'stat' is aliased to 'status'.

(Ada) Fix print of array using non-contiguous enumeration indexes
Consider the following code:
type Index is (Index1, Index2);
Size : constant Integer := 10;
for Index use (Index1 => 1, Index2 => Size);
type Array_Index_Enum is array (Index) of Integer;
my_table : Array_Index_Enum :=(others => 42);
When compiling the code above with a compiler where the GNAT encodings
are turned off (which can be temporarily emulated by using the compiler
switch -fgnat-encodings=minimal), printing this table in gdb leads to:
(gdb) p my_table
$1 = (42, 42, 4203344, 10, -8320, 32767, 4203465, 0, 0, 0)
The displayed content is wrong since the handling part believes
that the length of the array is max index value (10) minus the
first index value (1) i+ 1 = 10 which is wrong since index are not
contiguous in this case.
The right behavior is to detect that the array is using enumeration
index hence parse the enumeration values in order to get the number
of indexes in this array (2 indexes here).
This patch fixes this issue and changes the output as follow:
(gdb) p my_table
$1 = (42, 42)
gdb/ChangeLog:
* ada-valprint.c (val_print_packed_array_elements): Use
proper number of elements when printing an array indexed
by an enumeration type.

Remove dwarf2_per_objfile global
This patch removes the global variable dwarf2_per_objfile. This global
variable is set at the various entry points of dwarf2read.c (using
dw2_setup), and is referred to throughout the file. Instead of passing
data between functions in global variables like this one, it would be
better if the functions that depend on it either received it as argument
or got it from the existing arguments they receive. For example, a
function receiving a reference to a dwarf2_per_cu_data can access it
from dwarf2_per_cu_data::dwarf2_per_objfile.
This patch has been tested on the buildbot.

C++ify xmethod_worker, get rid of VEC(xmethod_worker_ptr)
The initial goal of this patch was to remove the usage of
VEC(xmethod_worker_ptr) and corresponding cleanups. I ended up having
to C++ify the xmethod_worker code, to be able to have xmethod_workers
free their data in destructors, and therefore be able to use vectors of
xmethod_worker unique_ptr.
The operations in extension_language_ops that act on one instance of
xmethod_worker (get result type, get args type, invoke) are transformed
to methods of xmethod_worker. xmethod_worker becomes an abstract base
class with virtual pure methods which python_xmethod_worker implements.
The only xmethod-related operation left in extension_language_ops is
get_matching_xmethod_workers, which returns a list of xmethod_workers.
The changes are relatively straightforward, but here are some notes on
things that may raise eyebrows:
- I was not really comfortable with the value_of_xmethod function. At
first it looks like a simple getter, so I considered making it a
method of xmethod_worker. But actually it creates a value and
transfers the ownership of the xmethod_worker to it. It would be a
bit weird and error-prone if calling a method on an object silently
removed the ownership of the object from the caller. To reflect the
behavior more accurately, I renamed it to value_from_xmethod and made
it accept an rvalue-reference (so the caller knows it gives away the
ownership). I noticed the backlink from xmethod_worker to its owning
value was not used, so I removed it.
- Some code, like get_matching_xmethod_workers, made each callee fill
a new vector, which was then merged in the result vector. I think
it's safe if we always pass the same vector around, and each
implementation just appends to it.
- The clone operation does not seem particularly useful, it is removed
in the following patch.

Fix regression: cannot start with LD_PRELOAD=libSegFault.so (PR gdb/18653#c7)
At https://sourceware.org/bugzilla/show_bug.cgi?id=18653#c7, Andrew
reports that the fix for PR gdb/18653 made GDB useless if you preload
libSegFault.so, because GDB internal-errors on startup:
$ LD_PRELOAD=libSegFault.so gdb
src/gdb/common/signals-state-save-restore.c:64: internal-error: unexpected signal handler
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Aborted (core dumped)
$
The internal error comes from the code saving the signal dispositions
inherited from gdb's parent:

instead:

Fix regresssion(internal-error) printing subprogram argument (PR gdb/22670)
At <https://sourceware.org/ml/gdb-patches/2017-12/msg00298.html>, Joel
wrote:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Consider the following code which first declares a tagged type (the
equivalent of a class in Ada), and then a procedure which takes a
pointer (access) to this type's 'Class.
package Pck is
type Top_T is tagged record
N : Integer := 1;
end record;
procedure Inspect (Obj: access Top_T'Class);
end Pck;
Putting a breakpoint in that procedure and then running to it triggers
an internal error:
(gdb) break inspect
(gdb) continue
Breakpoint 1, pck.inspect (obj=0x63e010
/[...]/gdb/stack.c:621: internal-error: void print_frame_args(symbol*, frame_info*, int, ui_file*): Assertion `nsym != NULL' failed.
What's special about this subprogram is that it takes an access to
what we call a 'Class type, and for implementation reasons, the
compiler adds an extra argument named "objL". If you are curious why,
it allows the compiler for perform dynamic accessibility checks that
are mandated by the language.
If we look at the location where we get the internal error (in
stack.c), we find that we are looping over the symbol of each
parameter, and for each parameter, we do:
/* We have to look up the symbol because arguments can have
two entries (one a parameter, one a local) and the one we
want is the local, which lookup_symbol will find for us.
[...]
nsym = lookup_symbol (SYMBOL_LINKAGE_NAME (sym),
b, VAR_DOMAIN, NULL).symbol;
gdb_assert (nsym != NULL);
The lookup_symbol goes through the lookup structure, which means the
symbol's linkage name ("objL") gets transformed into a
lookup_name_info object (in block_lookup_symbol), before it gets fed
to the block symbol dictionary iterators. This, in turn, triggers the
symbol matching by comparing the "lookup" name which, for Ada, means
among other things, lowercasing the given name to "objl". It is this
transformation that causes the lookup find no matches, and therefore
trip this assertion.
Going back to the "offending" call to lookup_symbol in stack.c, what
we are trying to do, here, is do a lookup by linkage name. So, I
think what we mean to be doing is a completely literal symbol lookup,
so maybe not even strcmp_iw, but actually just plain strcmp???
In the past, in practice, you could get that effect by doing a lookup
using the C language. But that doesn't work, because we still end up
somehow using Ada's lookup_name routine which transforms "objL".
So, ideally, as I hinted before, I think what we need is a way to
perform a literal lookup so that searches by linkage names like the
above can be performed.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This commit fixes the problem by implementing something similar to
Joel's literal idea, but with some important differences.
I considered adding a symbol_name_match_type::LINKAGE and supporting
searching by linkage name for any language, but the problem with that
is that the dictionaries only work with SYMBOL_SEARCH_NAME, because
that's what is used for hashing. We'd need separate dictionaries for
hashed linkage names.
So with the current symbol tables infrastructure, it's not literal
linkage names that we want to pass down, but instead literal _search_
names (SYMBOL_SEARCH_NAME, etc.).
However, psymbols have no overload/function parameter info in C++, so
a straight strcmp doesn't work properly for C++ name matching.
So what we do is be a little less aggressive then and add a new
symbol_name_match_type::SEARCH_SYMBOL instead that takes as input a
non-user-input search symbol, and then we skip any decoding/demangling
steps and make:
- Ada treat that as a verbatim match,
- other languages treat it as symbol_name_match_type::FULL.
This also fixes the new '"maint check-psymtabs" for Ada' testcase for
me (gdb.ada/maint_with_ada.exp). I've not removed the kfail yet
because Joel still sees that testcase failing with this patch.
That'll be fixed in follow up patches.

(Ada) problem printing renaming which references a subprogram parameter
Consider the following code, which creates a local variable B
which is a renaming whose expression references a subprogram
parameter:
procedure Flip (Bits : in out Bits_Type; I : Natural) is
begin
declare
B : Boolean renames Bits (I);
begin
B := not B; -- BREAK
end;
end Flip;
Trying to print the value of B when at the "BREAK" line currently
does not work:
(gdb) p b
Could not find i
What happens is the following: For the renaming, GNAT generates
a variable whose name is encoded as follow:
b___XR_bits___XEXSi
GDB properly detects that variable, determines that, to compute
the variable's value, we start from the symbol "Bits", which
we then have to subscript (XS) using 'i' as the index. The error
occurs while trying to find 'i'.
This is because we forgot to pass the block in the call to
ada_lookup_encoded_symbol, which this patch fixes.

* ada-exp.y (write_object_renaming): When subscripting an array
using a symbol as the index, pass the block in call to
ada_lookup_encoded_symbol when looking that symbol up.

(Ada) Fix Length attribute on array access
Consider the following variable "Indexed_By_Enum", declared as
an access to an array whose index type is an enumerated type
whose underlying values have "gaps":
type Enum_With_Gaps is (LIT0, LIT1, LIT2, LIT3, LIT4);
for Enum_With_Gaps use (LIT0 => 3,
LIT1 => 5,
LIT2 => 8,
LIT3 => 13,
LIT4 => 21);
for Enum_With_Gaps'size use 16;
type MyWord is range 0 .. 16#FFFF# ;
for MyWord'Size use 16;
type AR is array (Enum_With_Gaps range <>) of MyWord;
type AR_Access is access AR;
Indexed_By_Enum : AR_Access :=
new AR'(LIT1 => 1, LIT2 => 43, LIT3 => 42, LIT4 => 41);
Trying to print the length (number of elements) of this array using
the 'Length attribute does not work:
(gdb) print indexed_by_enum'length
'POS only defined on discrete types
The problem occurs while trying to get the array's index type.
It was using TYPE_INDEX_TYPE for that. It does not work for Ada arrays
in general; use ada_index_type instead.
gdb/ChangeLog:
* ada-lang.c (ada_array_length): Use ada_index_type instead of
TYPE_INDEX_TYPE.

memory error printing component of record from convenience variable
Consider the following situation Ada code:
type Kind_T is (One, Two, Three);
type Time_Set_T is array (Kind_T) of Integer;
type T is record
Started : Time_Set_T;
end record;
Null_T : constant T := (Started => (others => 0));
My_Item : Pck.T := Pck.Null_T;
Trying to print the value of My_Item.Started is no problem:
(gdb) p item.started
$1 = (0, 0, 0)
However, if you save My_Item into a convenience variable first,
and then try to print a component of that record, you get
an unexpected memory error, instead of getting the same result.
For instance:
(gdb) set variable $item := item
(gdb) p $item.started
Cannot access memory at address 0x0
The issue occurs when, after we extracted the component from
the convenience variable, we next try to "fix" it (which is
ada-lang speak for resolving the type into a static type).
This is done in ada_to_fixed_value, which delegates to
ada_to_fixed_value_create via:
val = ada_to_fixed_value_create (value_type (val),
value_address (val), val);
And looking at ada_to_fixed_value_create, we see that:
struct type *type = ada_to_fixed_type (type0, 0, address, NULL, 1);
if (type == type0 && val0 != NULL)
return val0;
else
return value_from_contents_and_address (type, 0, address);
The part that interests us, in this case, is the "else" branch,
where we obviously make the implicit assumption that our object
has an address, which is not true, in this case, because we are
actually dealing with a convenience variable.
This patch plugs that hole by adding special handing for situations
where val does not live in memory. In that case, we just create
a not_lval value using val's contents.
gdb/ChangeLog:
* ada-lang.c (ada_to_fixed_value_create): Add handling of
the case where VALUE_LVAL (val0) is not lval_memory.
gdb/testsuite/ChangeLog:
* gdb.ada/convvar_comp: New testcase.

(Ada) New command to stop at start of exception handler.
When using gdb for debugging Ada source code, there are several catchpoint
types you can define in order to stop upon certain conditions. Let's
use this small example:
procedure Foo is
begin
begin
raise Constraint_Error;
exception
when Program_Error =>
null;
when Constraint_Error =>
null;
when others =>
null;
end;
end Foo;
One can stop when the exception is being raised by using the exception
catchpoint like below:
(gdb) catch exception
Catchpoint 1: all Ada exceptions
(gdb)
In that case, when running Foo, gdb will stop at the line where the exception
was raised:
begin
>>> raise Constraint_Error;
exception
This patch introduces new type of catchpoint, when the user wants to stop
at the location of the exception handling.
Imagine we want to stop on any exception handled by the program, we can do:
(gdb) catch handlers
Catchpoint 1: all Ada exceptions handlers
(gdb) r
Starting program: /tmp/foo
By doing so, when running Foo, gdb will stop here:
Catchpoint 1, exception at 0x000000000040255a in foo () at foo.adb:25
25 when Constraint_Error =>
(gdb)
It is also possible to stop when the Constraint_Error exception is being
handled in this program. With this patch, we can use:
(gdb) catch handlers Constraint_Error
Catchpoint 1: `Constraint_Error' Ada exception handlers
(gdb)
Like for other catchpoint, you can set a condition when adding a catchpoint
on exception handlers.
Here the handlers catchpoint checks Global_Var:
(gdb) catch handlers Constraint_Error if Global_Var /= 0

[gdb/Ada] slices of arrays with dynamic strides
Consider the following Ada code:
procedure Nested (L, U : Integer) is
subtype Small_Type is Integer range L .. U;
type Record_Type (I : Small_Type := L) is record
S : String (1 .. I);
end record;
type Array_Type is array (Integer range <>) of Record_Type;
A1 : Array_Type :=
(1 => (I => 0, S => <>),
2 => (I => 1, S => "A"),
3 => (I => 2, S => "AB"));
procedure Discard (R : Record_Type) is
begin
null;
end Discard;
begin
Discard (A1 (1)); -- STOP
end;
Trying to print a slice of that array currently yields:
(gdb) p a1(1..3)
$1 = ((i => 0, s => ""), (i => 0, s => ""), (i => 0, s => ""))
We expected instead:
(gdb) p a1(1..3)
$1 = ((i => 0, s => ""), (i => 1, s => "A"), (i => 2, s => "AB"))
This is because the functions we use in ada-lang.c to create the type
of the array slice (ada_value_slice and ada_value_slice_from_ptr) was
not taking into account the stride of the array. This patch fixes this.
gdb/ChangeLog:
* ada-lang.c (ada_value_slice_from_ptr): Take array stride into
account when creating the array type of the slice.
(ada_value_slice): Likewise.
gdb/testsuite/ChangeLog:
* gdb.ada/dyn_stride.exp: Add slice test.
Note that, with the current use of ada_value_slice, the enhancement
to handle dynamic array strides seems unnecessary, because I do not
see how an array with a dynamic stride can be referenced by either
by reference or pointer. Since references are coerced to array pointers,
in both cases, the slice is performed by ada_value_slice_from_ptr.
But ada_value_slice is enhanced nonetheless, in the spirit of making
the code more robust, in case we missed something, and also as similar
as possible with its from_ptr counterpart.

Add support for dynamic DW_AT_byte_stride.
This patch adds support for DW_AT_byte_stride, using Ada as one
example of where this would be useful. However, the implementation
is language-agnostic.
Consider the following Ada code:
procedure Nested (L, U : Integer) is
subtype Small_Type is Integer range L .. U;
type Record_Type (I : Small_Type := L) is record
S : String (1 .. I);
end record;
type Array_Type is array (Integer range <>) of Record_Type;
A1 : Array_Type :=
(1 => (I => 0, S => <>),
2 => (I => 1, S => "A"),
3 => (I => 2, S => "AB"));
procedure Discard (R : Record_Type) is
begin
null;
end Discard;
begin
Discard (A1 (1)); -- STOP
end;
It defines an array A1 of Record_Type, which is a variant record
type whose maximum size actually depends on the value of the
parameters passed when calling Nested. As a result, the stride
of the array A1 cannot be known statically, which leads the compiler
to generate a dynamic DW_AT_byte_stride attribute for our type.
Here is what the debugging info looks like with GNAT:
.uleb128 0x10 # (DIE (0x14e) DW_TAG_array_type)
.long .LASF17 # DW_AT_name: "foo__nested__T18b"
.long 0x141 # DW_AT_byte_stride
.long 0xdc # DW_AT_type
.uleb128 0x11 # (DIE (0x15f) DW_TAG_subrange_type)
.long 0x166 # DW_AT_type
.byte 0x3 # DW_AT_upper_bound
.byte 0 # end of children of DIE 0x14e
There DW_AT_byte_stride is a reference to a local (internal)
variable:
.uleb128 0x9 # (DIE (0x141) DW_TAG_variable)
.long .LASF6 # DW_AT_name: "foo__nested__T18b___PAD___XVZ"
This patch enhances GDB to handle this dynamic byte stride attribute
by first adding a new dynamic_prop_node_kind (DYN_PROP_BYTE_STRIDE)
to store the array dynamic stride info (when dynamic). It then enhances
the dynamic type resolver to handle this dynamic property.
Before applying this patch, trying to print the value of some of
A1's elements after having stopped at the "STOP" comment does not
work. For instance:
(gdb) p a1(2)
Cannot access memory at address 0x80000268dec0
With this patch applied, GDB now prints the value of all 3 elements
correctly:
(gdb) print A1(1)
$1 = (i => 0, s => "")
(gdb) print A1(2)
$2 = (i => 1, s => "A")
(gdb) print A1(3)
$3 = (i => 2, s => "AB")
