[PowerPC] Consolidate linux target description selection
Share target description declarations and selection among ppc linux
native targets, core files, gdbserver and IPA.
To avoid complicated define guards, gdbserver and IPA now have
declarations for all descriptions, including 64-bit generated
descriptions when compiled in 32-bit mode. These have always been
linked into the gdbserver and IPA binaries. Because they might be
uninitialized, the selection function checks that the selected
description is initialized.

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.

PowerPC64 ELFv2 ABI: skip global entry point code
This patch handles another aspect of the ELFv2 ABI, which unfortunately
requires common code changes.
In ELFv2, functions may provide both a global and a local entry point.
The global entry point (where the function symbol points to) is intended
to be used for function-pointer or cross-module (PLT) calls, and requires
r12 to be set up to the entry point address itself. The local entry
point (which is found at a fixed offset after the global entry point,
as defined by bits in the symbol table entries' st_other field), instead
expects r2 to be set up to the current TOC.
Now, when setting a breakpoint on a function by name, you really want
that breakpoint to trigger either way, no matter whether the function
is called via its local or global entry point. Since the global entry
point will always fall through into the local entry point, the way to
achieve that is to simply set the breakpoint at the local entry point.
One way to do that would be to have prologue parsing skip the code
sequence that makes up the global entry point. Unfortunately, this
does not work reliably, since -for optimized code- GDB these days
will not actuall invoke the prologue parsing code but instead just
set the breakpoint at the symbol address and rely on DWARF being
correct at any point throughout the function ...
Unfortunately, I don't really see any way to express the notion of
local entry points with the current set of gdbarch callbacks.
Thus this patch adds a new callback, skip_entrypoint, that is
somewhat analogous to skip_prologue, but is called every time
GDB needs to determine a function start address, even in those
cases where GDB decides to not call skip_prologue.
As a side effect, the skip_entrypoint implementation on ppc64
does not need to perform any instruction parsing; it can simply
rely on the local entry point flags in the symbol table entry.
With this implemented, two test cases would still fail to set
the breakpoint correctly, but that's because they use the construct:
gdb_test "break *hello"
Now, using "*hello" explicitly instructs GDB to set the breakpoint
at the numerical value of "hello" treated as function pointer, so
it will by definition only hit the global entry point.
I think this behaviour is unavoidable, but acceptable -- most people
do not use this construct, and if they do, they get what they
asked for ...
In one of those two test cases, use of this construct is really
not appropriate. I think this was added way back when as a means
to work around prologue skipping problems on some platforms. These
days that shouldn't really be necessary any more ...
For the other (step-bt), we really want to make sure backtracing
works on the very first instruction of the routine. To enable that
test also on powerpc64le-linux, we can modify the code to call the
test function via function pointer (which makes it use the global
entry point in the ELFv2 ABI).
gdb/ChangeLog:
* gdbarch.sh (skip_entrypoint): New callback.
* gdbarch.c, gdbarch.h: Regenerate.
* symtab.c (skip_prologue_sal): Call gdbarch_skip_entrypoint.

ELF/BFD,GDB: Handle both variants of the 32-bit Linux core PRPSINFO note
Fix commit 70a38d42c5b3 ("New entry points for writing Linux NT_PRPSINFO
notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>,
and commit b3ac9c77560a ("Put more info in NT_PRPSINFO Linux notes"),
<https://sourceware.org/ml/binutils/2013-02/msg00024.html>, and handle
both variants of the 32-bit Linux core PRPSINFO note across all targets.
The 32-bit Linux core PRPSINFO note matches the 32-bit kernel structure,
defined as follows:
(gdb) ptype struct elf_prpsinfo
type = struct elf_prpsinfo {
char pr_state;
char pr_sname;
char pr_zomb;
char pr_nice;
unsigned long pr_flag;
__kernel_uid_t pr_uid;
__kernel_gid_t pr_gid;
pid_t pr_pid;
pid_t pr_ppid;
pid_t pr_pgrp;
pid_t pr_sid;
char pr_fname[16];
char pr_psargs[80];
}
(gdb)
where the individual data types of most members are the same across all
32-bit Linux ports, with the exception of `__kernel_uid_t' and
`__kernel_gid_t'. These are defined in <asm-generic/posix_types.h> as
32-bit `unsigned int' by default, however overridden as 16-bit `unsigned
short' in port-specific <asm/posix_types.h> for a few targets, mostly
earlier ports of Linux, specifically: ARM, CRIS, FR-V, M32R, m68k,
MN10300/AM33, s390, SuperH, SPARC and i386.
The default is the same as the PowerPC variant already handled, as from
the commits referred. Make the special PowerPC case generic then,
removing the GDB part, and provide a backend flag to switch between the
two cases possible, with the 32-bit one being the default and the 16-bit
one explicitly selected. Set the flag in the target backends affected.

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

/* ppc_linux_memory_remove_breakpoints attempts to remove a breakpoint
|
|
|
|
in much the same fashion as memory_remove_breakpoint in mem-break.c,
|
|
|
|
but is careful not to write back the previous contents if the code
|
|
|
|
in question has changed in between inserting the breakpoint and
|
|
|
|
removing it.
|
|
|
|
|
|
|
|
Here is the problem that we're trying to solve...
|
|
|
|
|
|
|
|
Once upon a time, before introducing this function to remove
|
|
|
|
breakpoints from the inferior, setting a breakpoint on a shared
|
|
|
|
library function prior to running the program would not work
|
|
|
|
properly. In order to understand the problem, it is first
|
|
|
|
necessary to understand a little bit about dynamic linking on
|
|
|
|
this platform.
|
|
|
|
|
|
|
|
A call to a shared library function is accomplished via a bl
|
|
|
|
(branch-and-link) instruction whose branch target is an entry
|
|
|
|
in the procedure linkage table (PLT). The PLT in the object
|
|
|
|
file is uninitialized. To gdb, prior to running the program, the
|
|
|
|
entries in the PLT are all zeros.
|
|
|
|
|
|
|
|
Once the program starts running, the shared libraries are loaded
|
|
|
|
and the procedure linkage table is initialized, but the entries in
|
|
|
|
the table are not (necessarily) resolved. Once a function is
|
|
|
|
actually called, the code in the PLT is hit and the function is
|
|
|
|
resolved. In order to better illustrate this, an example is in
|
|
|
|
order; the following example is from the gdb testsuite.
|
|
|
|
|
|
|
|
We start the program shmain.
|
|
|
|
|
|
|
|
[kev@arroyo testsuite]$ ../gdb gdb.base/shmain
|
|
|
|
[...]
|
|
|
|
|
|
|
|
We place two breakpoints, one on shr1 and the other on main.
|
|
|
|
|
|
|
|
(gdb) b shr1
|
|
|
|
Breakpoint 1 at 0x100409d4
|
|
|
|
(gdb) b main
|
|
|
|
Breakpoint 2 at 0x100006a0: file gdb.base/shmain.c, line 44.
|
|
|
|
|
|
|
|
Examine the instruction (and the immediatly following instruction)
|
|
|
|
upon which the breakpoint was placed. Note that the PLT entry
|
|
|
|
for shr1 contains zeros.
|
|
|
|
|
|
|
|
(gdb) x/2i 0x100409d4
|
|
|
|
0x100409d4 <shr1>: .long 0x0
|
|
|
|
0x100409d8 <shr1+4>: .long 0x0
|
|
|
|
|
|
|
|
Now run 'til main.
|
|
|
|
|
|
|
|
(gdb) r
|
|
|
|
Starting program: gdb.base/shmain
|
|
|
|
Breakpoint 1 at 0xffaf790: file gdb.base/shr1.c, line 19.
|
|
|
|
|
|
|
|
Breakpoint 2, main ()
|
|
|
|
at gdb.base/shmain.c:44
|
|
|
|
44 g = 1;
|
|
|
|
|
|
|
|
Examine the PLT again. Note that the loading of the shared
|
|
|
|
library has initialized the PLT to code which loads a constant
|
|
|
|
(which I think is an index into the GOT) into r11 and then
|
|
|
|
branchs a short distance to the code which actually does the
|
|
|
|
resolving.
|
|
|
|
|
|
|
|
(gdb) x/2i 0x100409d4
|
|
|
|
0x100409d4 <shr1>: li r11,4
|
|
|
|
0x100409d8 <shr1+4>: b 0x10040984 <sg+4>
|
|
|
|
(gdb) c
|
|
|
|
Continuing.
|
|
|
|
|
|
|
|
Breakpoint 1, shr1 (x=1)
|
|
|
|
at gdb.base/shr1.c:19
|
|
|
|
19 l = 1;
|
|
|
|
|
|
|
|
Now we've hit the breakpoint at shr1. (The breakpoint was
|
|
|
|
reset from the PLT entry to the actual shr1 function after the
|
|
|
|
shared library was loaded.) Note that the PLT entry has been
|
2011-01-10 21:38:51 +01:00
|
|
|
resolved to contain a branch that takes us directly to shr1.
|
2000-02-26 10:25:50 +01:00
|
|
|
(The real one, not the PLT entry.)
|
|
|
|
|
|
|
|
(gdb) x/2i 0x100409d4
|
|
|
|
0x100409d4 <shr1>: b 0xffaf76c <shr1>
|
|
|

0x100409d8 <shr1+4>: b 0x10040984 <sg+4>
|
|
|
|
|
|
|
|
The thing to note here is that the PLT entry for shr1 has been
|
|
|
|
changed twice.
|
|
|
|
|
|
|
|
Now the problem should be obvious. GDB places a breakpoint (a
|
2011-01-10 21:38:51 +01:00
|
|
|
trap instruction) on the zero value of the PLT entry for shr1.
|
2000-02-26 10:25:50 +01:00
|
|
|
Later on, after the shared library had been loaded and the PLT
|
|
|
|
initialized, GDB gets a signal indicating this fact and attempts
|
|
|
|
(as it always does when it stops) to remove all the breakpoints.
|
|
|
|
|
|
|
|
The breakpoint removal was causing the former contents (a zero
|
|
|
|
word) to be written back to the now initialized PLT entry thus
|
|
|
|
destroying a portion of the initialization that had occurred only a
|
|
|
|
short time ago. When execution continued, the zero word would be
|
2011-02-27 17:25:38 +01:00
|
|
|
executed as an instruction an illegal instruction trap was
|
2000-02-26 10:25:50 +01:00
|
|
|
generated instead. (0 is not a legal instruction.)
|
|
|
|
|
|
|
|
The fix for this problem was fairly straightforward. The function
|
|
|
|
memory_remove_breakpoint from mem-break.c was copied to this file,
|
|
|
|
modified slightly, and renamed to ppc_linux_memory_remove_breakpoint.
|
|
|
|
In tm-linux.h, MEMORY_REMOVE_BREAKPOINT is defined to call this new
|
|
|
|
function.
|
|
|
|
|
|
|
|
The differences between ppc_linux_memory_remove_breakpoint () and
|
|
|
|
memory_remove_breakpoint () are minor. All that the former does
|
|
|
|
that the latter does not is check to make sure that the breakpoint
|
|
|
|
location actually contains a breakpoint (trap instruction) prior
|
|
|
|
to attempting to write back the old contents. If it does contain
|
2011-01-10 21:38:51 +01:00
|
|
|
a trap instruction, we allow the old contents to be written back.
|
2000-02-26 10:25:50 +01:00
|
|
|
Otherwise, we silently do nothing.
|
|
|
|
|
|
|
|
The big question is whether memory_remove_breakpoint () should be
|
|
|
|
changed to have the same functionality. The downside is that more
|
|
|
|
traffic is generated for remote targets since we'll have an extra
|
|
|
|
fetch of a memory word each time a breakpoint is removed.
|
|
|
|
|
|
|
|
For the time being, we'll leave this self-modifying-code-friendly
|
|
|
|
version in ppc-linux-tdep.c, but it ought to be migrated somewhere
|
|
|
|
else in the event that some other platform has similar needs with
|
|
|
|
regard to removing breakpoints in some potentially self modifying
|
|
|
|
code. */

Avoid software breakpoint's instruction shadow inconsistency
This change:
commit b775012e845380ed4c7421a1b87caf7bfae39f5f

* remote.c (remote_supports_cond_breakpoints): New forward
declaration.
[...]
changed the way breakpoints are inserted and removed such that
`insert_bp_location' can now be called with the breakpoint being handled
already in place, while previously the call was only ever made for
breakpoints that have not been put in place. This in turn caused an
issue for software breakpoints and targets for which a breakpoint's
`placed_address' may not be the same as the original requested address.
The issue is `insert_bp_location' overwrites the previously adjusted
value in `placed_address' with the original address, that is only
replaced back with the correct adjusted address later on when
`gdbarch_breakpoint_from_pc' is called. Meanwhile there's a window
where the value in `placed_address' does not correspond to data stored
in `shadow_contents', leading to incorrect instruction bytes being
supplied when `one_breakpoint_xfer_memory' is called to supply the
instruction overlaid by the breakpoint.
And this is exactly what happens on the MIPS target with software
breakpoints placed in microMIPS code. In this case not only
`placed_address' is not the original address because of the ISA bit, but
`mips_breakpoint_from_pc' has to read the original instruction to
determine which one of the two software breakpoint instruction encodings
to choose as well. The 16-bit encoding is used to replace 16-bit
instructions and similarly the 32-bit one is used with 32-bit
instructions, to satisfy branch delay slot size requirements.
The mismatch between `placed_address' and the address data in
`shadow_contents' has been obtained from leads to the wrong encoding
being used in some cases, which in the case of a 32-bit software
breakpoint instruction replacing a 16-bit instruction causes corruption
to the adjacent following instruction and leads the debug session astray
if execution reaches there e.g. with a jump.
To address this problem I made the change below, that adds a
`reqstd_address' field to `struct bp_target_info' and leaves
`placed_address' unchanged once it has been set. This ensures data in
`shadow_contents' is always consistent with `placed_address'.
This approach also has this good side effect that all the places that
examine the breakpoint's address see a consistent value, either
`reqstd_address' or `placed_address', as required. Currently some
places see either the original or the adjusted address in
`placed_address', depending on whether they have been called before
`gdbarch_remote_breakpoint_from_pc' or afterwards. This is in
particular true for subsequent calls to
`gdbarch_remote_breakpoint_from_pc' itself, e.g. from
`one_breakpoint_xfer_memory'. This is also important for places like
`find_single_step_breakpoint' where a breakpoint's address is compared
to the raw value of $pc.

simpler to catch potential problem spots, this patch changes the
representation of minimal symbols and introduces new
minimal-symbol-specific variants of the various accessors. This is
necessary because it would be excessively ambitious to try to convert
all the symbol types at once.
The core of this change is just renaming a field in minimal_symbol;
the rest is just a fairly mechanical rewording.

[PowerPC] Add support for EBB and PMU registers
This patch adds support for registers of the Event Based Branching and
Performance Monitoring Units for the powerpc linux native and core
file targets, and for the powerpc linux server stub.
All three EBB registers are accessible. Only a subset of the PMU
registers can be accessed through ptrace. Because of this, the PMU
registers are enumerated individually in gdbarch_tdep, as opposed to
having a single "have_pmu" flag. This is intended to make it easier
to add additional PMU registers in the future, since checking a
"have_pmu" flag elsewhere in the code would no longer be correct. The
tdesc feature is named org.gnu.gdb.power.linux.pmu because of this.
It's unclear if it makes sense to save and restore these registers
across function calls, since some of them can be modified
asynchronously. They are also not tracked in record-replay mode.
The kernel can return ENODATA when ptrace is used to get the EBB
registers, unless a linux performance event that uses EBB is open in
the inferior. For this reason, the "fill" functions in the server
stub for the ebb register sets is not implemented.
Since gdbserver writes all registers in one go before resuming the
inferior, this error would not be detected at the time the user tries
to write to one of the registers on the client side, and gdbserver
would print out warnings every time it resumes the inferior when no
ebb performance event is opened, so there is currently no
straightforward way to handle this case. This means the ebb registers
in the client-side regcache can become dirty when the user tries to
write to them, until the inferior is resumed and stopped again.
A related issue is that 'G' packets used to write to unrelated
registers will include bad data for the EBB registers if they are
unavailable, since no register status information is included in the
'G' packet. This data won't be written to the inferior by the
gdbserver stub because the "fill" functions are not implemented, and
currently the gdbserver stub doesn't change the status of the
registers in its own regcache in response to 'G' packets.
Another limitation for the ebb registers is that traceframes don't
record if registers are available or not, so if these registers are
collected when a tracepoint is hit and the inferior has no ebb event
opened, the user will see zero values for all of them, instead of the
usual <unavailable>.
Because these registers are often unavailable, trying to store them
with target_store_registers with -1 for the regno argument (all
registers) would almost always fail, so they are ignored in this case.

pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers

These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are

The 32-bit regmap is the same for both endian types because the
|
|
|
|
fields are all 4-byte long.
|
|
|
|
|
|
|
|
The layout of checkpointed GPR regset is the same as a regular
|
|
|
|
struct pt_regs, but we skip all registers that are not actually
|
|
|
|
checkpointed by the processor (e.g. msr, nip), except when
|
|
|
|
generating a core file. The 64-bit regset is 48 * 8 bytes long.
|
|
|
|
In some 64-bit kernels, the regset for a 32-bit inferior has the
|
|
|
|
same length, but all the registers are squeezed in the first half
|
|
|
|
(48 * 4 bytes). The pt_regs struct calls the regular cr ccr, but
|
|
|
|
we use ccr for "checkpointed condition register". Note that CR
|
|
|
|
(condition register) field 0 is not checkpointed, but the kernel
|
|
|
|
returns all 4 bytes. The skipped registers should not be touched
|
|
|
|
when writing the regset to the inferior (with
|
|
|
|
PTRACE_SETREGSET). */

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

capable core file generation support) is replaced by an iterator
method. Overall, this reduces the code a bit, and it allows for more
flexibility.

Replace 'core_regset_sections' by iterator method
The core_regset_sections list in gdbarch (needed for multi-arch
capable core file generation support) is replaced by an iterator
method. Overall, this reduces the code a bit, and it allows for more
flexibility.

Add 'regset' parameter to 'iterate_over_regset_sections_cb'
This adds the 'regset' parameter to the iterator callback.
Consequently the 'regset_from_core_section' method is dropped for all
targets that provide the iterator method.
This change prepares for replacing regset_from_core_section
everywhere, thereby eliminating one gdbarch interface. Since the
iterator is usually no more complex than regset_from_core_section
alone, targets that previously didn't define core_regset_sections will
then gain multi-arch capable core file generation support without
increased complexity.
gdb/ChangeLog:
* gdbarch.sh (iterate_over_regset_sections_cb): Add regset
parameter.
* gdbarch.h: Regenerate.
* corelow.c (sniff_core_bfd): Don't sniff if gdbarch has a regset
iterator.
(get_core_register_section): Add parameter 'regset' and use it, if
set. Add parameter 'min_size' and verify the bfd section size
against it.
(get_core_registers_cb): Add parameter 'regset' and pass it to
get_core_register section. For the "standard" register sections
".reg" and ".reg2", set an appropriate default for human_name.
(get_core_registers): Don't abort when the gdbarch has an iterator
but no regset_from_core_section. Add NULL/0 for parameters
'regset'/'min_size' in calls to get_core_register_section.
* linux-tdep.c (linux_collect_regset_section_cb): Add parameter
'regset' and use it instead of calling the
regset_from_core_section gdbarch method.
* i386-tdep.h (struct gdbarch_tdep): Add field 'fpregset'.
* i386-tdep.c (i386_supply_xstateregset)
(i386_collect_xstateregset, i386_xstateregset): Moved to
i386-linux-tdep.c.

.reg-xstate.
(i386_gdbarch_init): Set tdep field 'fpregset'. Enable generic

[PowerPC] Add support for EBB and PMU registers
This patch adds support for registers of the Event Based Branching and
Performance Monitoring Units for the powerpc linux native and core
file targets, and for the powerpc linux server stub.
All three EBB registers are accessible. Only a subset of the PMU
registers can be accessed through ptrace. Because of this, the PMU
registers are enumerated individually in gdbarch_tdep, as opposed to
having a single "have_pmu" flag. This is intended to make it easier
to add additional PMU registers in the future, since checking a
"have_pmu" flag elsewhere in the code would no longer be correct. The
tdesc feature is named org.gnu.gdb.power.linux.pmu because of this.
It's unclear if it makes sense to save and restore these registers
across function calls, since some of them can be modified
asynchronously. They are also not tracked in record-replay mode.
The kernel can return ENODATA when ptrace is used to get the EBB
registers, unless a linux performance event that uses EBB is open in
the inferior. For this reason, the "fill" functions in the server
stub for the ebb register sets is not implemented.
Since gdbserver writes all registers in one go before resuming the
inferior, this error would not be detected at the time the user tries
to write to one of the registers on the client side, and gdbserver
would print out warnings every time it resumes the inferior when no
ebb performance event is opened, so there is currently no
straightforward way to handle this case. This means the ebb registers
in the client-side regcache can become dirty when the user tries to
write to them, until the inferior is resumed and stopped again.
A related issue is that 'G' packets used to write to unrelated
registers will include bad data for the EBB registers if they are
unavailable, since no register status information is included in the
'G' packet. This data won't be written to the inferior by the
gdbserver stub because the "fill" functions are not implemented, and
currently the gdbserver stub doesn't change the status of the
registers in its own regcache in response to 'G' packets.
Another limitation for the ebb registers is that traceframes don't
record if registers are available or not, so if these registers are
collected when a tracepoint is hit and the inferior has no ebb event
opened, the user will see zero values for all of them, instead of the
usual <unavailable>.
Because these registers are often unavailable, trying to store them
with target_store_registers with -1 for the regno argument (all
registers) would almost always fail, so they are ignored in this case.

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

Replace 'core_regset_sections' by iterator method
The core_regset_sections list in gdbarch (needed for multi-arch
capable core file generation support) is replaced by an iterator
method. Overall, this reduces the code a bit, and it allows for more
flexibility.

Remove.
(i386_linux_iterate_over_regset_sections): New.
(i386_linux_init_abi): Don't choose a regset section list, but
install new iterator in gdbarch.
* linux-tdep.c (struct linux_collect_regset_section_cb_data): New.
(linux_collect_regset_section_cb): New function, logic moved
from...
(linux_collect_thread_registers): ...loop body here. Use iterator
method instead of walking through list.

Use thread_info and inferior pointers more throughout
This is more preparation bits for multi-target support.
In a multi-target scenario, we need to address the case of different
processes/threads running on different targets that happen to have the
same PID/PTID. E.g., we can have both process 123 in target 1, and
process 123 in target 2, while they're in reality different processes
running on different machines. Or maybe we've loaded multiple
instances of the same core file. Etc.
To address this, in my WIP multi-target branch, threads and processes
are uniquely identified by the (process_stratum target_ops *, ptid_t)
and (process_stratum target_ops *, pid) tuples respectively. I.e.,
each process_stratum instance has its own thread/process number space.
As you can imagine, that requires passing around target_ops * pointers
in a number of functions where we're currently passing only a ptid_t
or an int. E.g., when we look up a thread_info object by ptid_t in
find_thread_ptid, the ptid_t alone isn't sufficient.
In many cases though, we already have the thread_info or inferior
pointer handy, but we "lose" it somewhere along the call stack, only
to look it up again by ptid_t/pid. Since thread_info or inferior
objects know their parent target, if we pass around thread_info or
inferior pointers when possible, we avoid having to add extra
target_ops parameters to many functions, and also, we eliminate a
number of by ptid_t/int lookups.
So that's what this patch does. In a bit more detail:
- Changes a number of functions and methods to take a thread_info or
inferior pointer instead of a ptid_t or int parameter.
- Changes a number of structure fields from ptid_t/int to inferior or
thread_info pointers.
- Uses the inferior_thread() function whenever possible instead of
inferior_ptid.
- Uses thread_info pointers directly when possible instead of the
is_running/is_stopped etc. routines that require a lookup.
- A number of functions are eliminated along the way, such as:
int valid_gdb_inferior_id (int num);
int pid_to_gdb_inferior_id (int pid);
int gdb_inferior_id_to_pid (int num);
int in_inferior_list (int pid);
- A few structures and places hold a thread_info pointer across
inferior execution, so now they take a strong reference to the
(refcounted) thread_info object to avoid the thread_info pointer
getting stale. This is done in enable_thread_stack_temporaries and
in the infcall.c code.
- Related, there's a spot in infcall.c where using a RAII object to
handle the refcount would be handy, so a gdb::ref_ptr specialization
for thread_info is added (thread_info_ref, in gdbthread.h), along
with a gdb_ref_ptr policy that works for all refcounted_object types
(in common/refcounted-object.h).

Use thread_info and inferior pointers more throughout
This is more preparation bits for multi-target support.
In a multi-target scenario, we need to address the case of different
processes/threads running on different targets that happen to have the
same PID/PTID. E.g., we can have both process 123 in target 1, and
process 123 in target 2, while they're in reality different processes
running on different machines. Or maybe we've loaded multiple
instances of the same core file. Etc.
To address this, in my WIP multi-target branch, threads and processes
are uniquely identified by the (process_stratum target_ops *, ptid_t)
and (process_stratum target_ops *, pid) tuples respectively. I.e.,
each process_stratum instance has its own thread/process number space.
As you can imagine, that requires passing around target_ops * pointers
in a number of functions where we're currently passing only a ptid_t
or an int. E.g., when we look up a thread_info object by ptid_t in
find_thread_ptid, the ptid_t alone isn't sufficient.
In many cases though, we already have the thread_info or inferior
pointer handy, but we "lose" it somewhere along the call stack, only
to look it up again by ptid_t/pid. Since thread_info or inferior
objects know their parent target, if we pass around thread_info or
inferior pointers when possible, we avoid having to add extra
target_ops parameters to many functions, and also, we eliminate a
number of by ptid_t/int lookups.
So that's what this patch does. In a bit more detail:
- Changes a number of functions and methods to take a thread_info or
inferior pointer instead of a ptid_t or int parameter.
- Changes a number of structure fields from ptid_t/int to inferior or
thread_info pointers.
- Uses the inferior_thread() function whenever possible instead of
inferior_ptid.
- Uses thread_info pointers directly when possible instead of the
is_running/is_stopped etc. routines that require a lookup.
- A number of functions are eliminated along the way, such as:
int valid_gdb_inferior_id (int num);
int pid_to_gdb_inferior_id (int pid);
int gdb_inferior_id_to_pid (int num);
int in_inferior_list (int pid);
- A few structures and places hold a thread_info pointer across
inferior execution, so now they take a strong reference to the
(refcounted) thread_info object to avoid the thread_info pointer
getting stale. This is done in enable_thread_stack_temporaries and
in the infcall.c code.
- Related, there's a spot in infcall.c where using a RAII object to
handle the refcount would be handy, so a gdb::ref_ptr specialization
for thread_info is added (thread_info_ref, in gdbthread.h), along
with a gdb_ref_ptr policy that works for all refcounted_object types
(in common/refcounted-object.h).

[PowerPC] Consolidate linux target description selection
Share target description declarations and selection among ppc linux
native targets, core files, gdbserver and IPA.
To avoid complicated define guards, gdbserver and IPA now have
declarations for all descriptions, including 64-bit generated
descriptions when compiled in 32-bit mode. These have always been
linked into the gdbserver and IPA binaries. Because they might be
uninitialized, the selection function checks that the selected
description is initialized.

[PowerPC] Add support for EBB and PMU registers
This patch adds support for registers of the Event Based Branching and
Performance Monitoring Units for the powerpc linux native and core
file targets, and for the powerpc linux server stub.
All three EBB registers are accessible. Only a subset of the PMU
registers can be accessed through ptrace. Because of this, the PMU
registers are enumerated individually in gdbarch_tdep, as opposed to
having a single "have_pmu" flag. This is intended to make it easier
to add additional PMU registers in the future, since checking a
"have_pmu" flag elsewhere in the code would no longer be correct. The
tdesc feature is named org.gnu.gdb.power.linux.pmu because of this.
It's unclear if it makes sense to save and restore these registers
across function calls, since some of them can be modified
asynchronously. They are also not tracked in record-replay mode.
The kernel can return ENODATA when ptrace is used to get the EBB
registers, unless a linux performance event that uses EBB is open in
the inferior. For this reason, the "fill" functions in the server
stub for the ebb register sets is not implemented.
Since gdbserver writes all registers in one go before resuming the
inferior, this error would not be detected at the time the user tries
to write to one of the registers on the client side, and gdbserver
would print out warnings every time it resumes the inferior when no
ebb performance event is opened, so there is currently no
straightforward way to handle this case. This means the ebb registers
in the client-side regcache can become dirty when the user tries to
write to them, until the inferior is resumed and stopped again.
A related issue is that 'G' packets used to write to unrelated
registers will include bad data for the EBB registers if they are
unavailable, since no register status information is included in the
'G' packet. This data won't be written to the inferior by the
gdbserver stub because the "fill" functions are not implemented, and
currently the gdbserver stub doesn't change the status of the
registers in its own regcache in response to 'G' packets.
Another limitation for the ebb registers is that traceframes don't
record if registers are available or not, so if these registers are
collected when a tracepoint is hit and the inferior has no ebb event
opened, the user will see zero values for all of them, instead of the
usual <unavailable>.
Because these registers are often unavailable, trying to store them
with target_store_registers with -1 for the regno argument (all

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

[PowerPC] Consolidate linux target description selection
Share target description declarations and selection among ppc linux
native targets, core files, gdbserver and IPA.
To avoid complicated define guards, gdbserver and IPA now have
declarations for all descriptions, including 64-bit generated
descriptions when compiled in 32-bit mode. These have always been
linked into the gdbserver and IPA binaries. Because they might be
uninitialized, the selection function checks that the selected
description is initialized.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

native targets, core files, gdbserver and IPA.
To avoid complicated define guards, gdbserver and IPA now have
declarations for all descriptions, including 64-bit generated
descriptions when compiled in 32-bit mode. These have always been
linked into the gdbserver and IPA binaries. Because they might be
uninitialized, the selection function checks that the selected
description is initialized.

[PowerPC] Add support for EBB and PMU registers
This patch adds support for registers of the Event Based Branching and
Performance Monitoring Units for the powerpc linux native and core
file targets, and for the powerpc linux server stub.
All three EBB registers are accessible. Only a subset of the PMU
registers can be accessed through ptrace. Because of this, the PMU
registers are enumerated individually in gdbarch_tdep, as opposed to
having a single "have_pmu" flag. This is intended to make it easier
to add additional PMU registers in the future, since checking a
"have_pmu" flag elsewhere in the code would no longer be correct. The
tdesc feature is named org.gnu.gdb.power.linux.pmu because of this.
It's unclear if it makes sense to save and restore these registers
across function calls, since some of them can be modified
asynchronously. They are also not tracked in record-replay mode.
The kernel can return ENODATA when ptrace is used to get the EBB
registers, unless a linux performance event that uses EBB is open in
the inferior. For this reason, the "fill" functions in the server
stub for the ebb register sets is not implemented.
Since gdbserver writes all registers in one go before resuming the
inferior, this error would not be detected at the time the user tries
to write to one of the registers on the client side, and gdbserver
would print out warnings every time it resumes the inferior when no
ebb performance event is opened, so there is currently no
straightforward way to handle this case. This means the ebb registers
in the client-side regcache can become dirty when the user tries to
write to them, until the inferior is resumed and stopped again.
A related issue is that 'G' packets used to write to unrelated
registers will include bad data for the EBB registers if they are
unavailable, since no register status information is included in the
'G' packet. This data won't be written to the inferior by the
gdbserver stub because the "fill" functions are not implemented, and
currently the gdbserver stub doesn't change the status of the
registers in its own regcache in response to 'G' packets.
Another limitation for the ebb registers is that traceframes don't
record if registers are available or not, so if these registers are
collected when a tracepoint is hit and the inferior has no ebb event
opened, the user will see zero values for all of them, instead of the
usual <unavailable>.
Because these registers are often unavailable, trying to store them
with target_store_registers with -1 for the regno argument (all
registers) would almost always fail, so they are ignored in this case.

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

[PowerPC] Consolidate linux target description selection
Share target description declarations and selection among ppc linux
native targets, core files, gdbserver and IPA.
To avoid complicated define guards, gdbserver and IPA now have
declarations for all descriptions, including 64-bit generated
descriptions when compiled in 32-bit mode. These have always been
linked into the gdbserver and IPA binaries. Because they might be
uninitialized, the selection function checks that the selected
description is initialized.

PowerPC64 ELFv2 ABI: skip global entry point code
This patch handles another aspect of the ELFv2 ABI, which unfortunately
requires common code changes.
In ELFv2, functions may provide both a global and a local entry point.
The global entry point (where the function symbol points to) is intended
to be used for function-pointer or cross-module (PLT) calls, and requires
r12 to be set up to the entry point address itself. The local entry
point (which is found at a fixed offset after the global entry point,
as defined by bits in the symbol table entries' st_other field), instead
expects r2 to be set up to the current TOC.
Now, when setting a breakpoint on a function by name, you really want
that breakpoint to trigger either way, no matter whether the function
is called via its local or global entry point. Since the global entry
point will always fall through into the local entry point, the way to
achieve that is to simply set the breakpoint at the local entry point.
One way to do that would be to have prologue parsing skip the code
sequence that makes up the global entry point. Unfortunately, this
does not work reliably, since -for optimized code- GDB these days
will not actuall invoke the prologue parsing code but instead just
set the breakpoint at the symbol address and rely on DWARF being
correct at any point throughout the function ...
Unfortunately, I don't really see any way to express the notion of
local entry points with the current set of gdbarch callbacks.
Thus this patch adds a new callback, skip_entrypoint, that is
somewhat analogous to skip_prologue, but is called every time
GDB needs to determine a function start address, even in those
cases where GDB decides to not call skip_prologue.
As a side effect, the skip_entrypoint implementation on ppc64
does not need to perform any instruction parsing; it can simply
rely on the local entry point flags in the symbol table entry.
With this implemented, two test cases would still fail to set
the breakpoint correctly, but that's because they use the construct:
gdb_test "break *hello"
Now, using "*hello" explicitly instructs GDB to set the breakpoint
at the numerical value of "hello" treated as function pointer, so
it will by definition only hit the global entry point.
I think this behaviour is unavoidable, but acceptable -- most people
do not use this construct, and if they do, they get what they
asked for ...
In one of those two test cases, use of this construct is really
not appropriate. I think this was added way back when as a means
to work around prologue skipping problems on some platforms. These
days that shouldn't really be necessary any more ...
For the other (step-bt), we really want to make sure backtracing
works on the very first instruction of the routine. To enable that
test also on powerpc64le-linux, we can modify the code to call the
test function via function pointer (which makes it use the global
entry point in the ELFv2 ABI).
gdb/ChangeLog:
* gdbarch.sh (skip_entrypoint): New callback.
* gdbarch.c, gdbarch.h: Regenerate.
* symtab.c (skip_prologue_sal): Call gdbarch_skip_entrypoint.

start change to progspace independence
This patch starts changing minimal symbols to be independent of the
program space.
Specifically, it adds a new objfile parameter to MSYMBOL_VALUE_ADDRESS
and changes all the code to use it. This is needed so we can change
gdb to apply the section offset when a minsym's address is computed,
as opposed to baking the offsets into the symbol itself.
A few spots still need the unrelocated address. For these, we
introduce MSYMBOL_VALUE_RAW_ADDRESS.
As a convenience, we also add the new macro BMSYMBOL_VALUE_ADDRESS,
which computes the address of a bound minimal symbol. This just does
the obvious thing with the fields.
Note that this change does not actually enable program space
independence. That requires more changes to gdb. However, to ensure
that these changes compile properly, this patch does add the needed
section lookup code to MSYMBOL_VALUE_ADDRESS -- it just ensures it has
no effect at runtime by multiplying the offset by 0.

Remove `expout*' globals from parser-defs.h
This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated. This is the initial step to make our parser less
"globalized".
This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument. It is big, and has been
reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h
This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated. This is the initial step to make our parser less
"globalized".
This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument. It is big, and has been
reviewed at least 4 times, so I think everything is covered.

gdb/linux-record: Fix readdir and getdents handling
getdents buffer size is given in bytes, not dirent entries (which have
variable size anyway). We don't need size_dirent and size_dirent64 for
this reason.
readdir, on the other hand, needs size of old_linux_dirent, which is
a somewhat different structure. Accordingly, rename size_dirent
to size_old_dirent.

* aarch64-linux-tdep.c (aarch64_linux_init_abi): Remove
size_dirent{,64}, add size_old_dirent.

gdb/linux-record: Fix sizes of sigaction and sigset_t
The values were mistakenly set to size of glibc's sigset_t (128 bytes)
and sigaction (140 or 152 bytes) instead of the kernel ones. The kernel
has 4 or 8 byte old_sigset_t, 8 byte sigset_t, 16 or 32 byte old_sigaction,
20 or 32 byte sigaction.
gdb/ChangeLog:
* aarch64-linux-tdep.c (aarch64_linux_init_abi): Fix size_sigaction,
size_sigset_t, size_old_sigaction, size_old_sigset_t.

gdb/linux-record: Fix readdir and getdents handling
getdents buffer size is given in bytes, not dirent entries (which have
variable size anyway). We don't need size_dirent and size_dirent64 for
this reason.
readdir, on the other hand, needs size of old_linux_dirent, which is
a somewhat different structure. Accordingly, rename size_dirent
to size_old_dirent.
gdb/ChangeLog:
* aarch64-linux-tdep.c (aarch64_linux_init_abi): Remove
size_dirent{,64}, add size_old_dirent.
* amd64-linux-tdep.c (amd64_linux_init_abi): Remove size_dirent{,64},

Support 128-bit IEEE floating-point types on Intel and Power
Now that all the prerequisites are in place, this commit finally adds support
for handling the __float128 type on Intel and Power, by providing appropriate
platform-specific versions of the floatformat_for_type callback.
Since at this point we do not yet have any indication in the debug info to
distinguish different floating-point formats of the same length, we simply
use the type name as hint. Types named "__float128" get the IEEE format.
In addition to handling "__float128" itself, we also recognize "_Float128"
and (on Power) "_Float64x", as well as the complex versions of those.
(As pointed out by Joseph Myers, starting with GCC 7, __float128 is just
a typedef for _Float128 -- but it's good to handle this anyway.)
A new test case does some simple verification that the format is decoded
correctly, using both __float128 and "long double" to make sure using both
in the same file still works. Another new test verifies handling of the
_FloatN and _FloatNx types supported by GCC 7, as well as the complex
versions of those types.
Note that this still only supports basic format decoding and encoding.
We do not yet support the GNU extension 'g' suffix for __float128 constants.
In addition, since all *arithmetic* on floating-point values is still
performed in native host "long double" arithmetic, if that format is not
able to encode all target __float128 values, we may get incorrect results.
(To fix this would require implementing fully synthetic target floating-
point arithmetic along the lines of GCC's real.c, presumably using MPFR.)

Extend SystemTap SDT probe argument parser
This patch extends the current generic parser for SystemTap SDT probe
arguments. It can be almost considered a cleanup, but the main point of
it is actually to allow the generic parser to accept multiple prefixes
and suffixes for the its operands (i.e., integers, register names, and
register indirection).
I have chosen to implement this as a list of const strings, and declare
this list as "static" inside each target's method used to initialize
gdbarch.
This patch is actually a preparation for an upcoming patch for ARM,
which implements the support for multiple integer prefixes (as defined
by ARM's asm spec). And AArch64 will also need this, for the same
reason.
This patch was regtested on all architectures that it touches (i.e.,
i386, x86_64, ARM, PPC/PPC64, s390x and IA-64). No regressions were found.

Support 128-bit IEEE floating-point types on Intel and Power
Now that all the prerequisites are in place, this commit finally adds support
for handling the __float128 type on Intel and Power, by providing appropriate
platform-specific versions of the floatformat_for_type callback.
Since at this point we do not yet have any indication in the debug info to
distinguish different floating-point formats of the same length, we simply
use the type name as hint. Types named "__float128" get the IEEE format.
In addition to handling "__float128" itself, we also recognize "_Float128"
and (on Power) "_Float64x", as well as the complex versions of those.
(As pointed out by Joseph Myers, starting with GCC 7, __float128 is just
a typedef for _Float128 -- but it's good to handle this anyway.)
A new test case does some simple verification that the format is decoded
correctly, using both __float128 and "long double" to make sure using both
in the same file still works. Another new test verifies handling of the
_FloatN and _FloatNx types supported by GCC 7, as well as the complex
versions of those types.
Note that this still only supports basic format decoding and encoding.
We do not yet support the GNU extension 'g' suffix for __float128 constants.
In addition, since all *arithmetic* on floating-point values is still
performed in native host "long double" arithmetic, if that format is not
able to encode all target __float128 values, we may get incorrect results.
(To fix this would require implementing fully synthetic target floating-
point arithmetic along the lines of GCC's real.c, presumably using MPFR.)

Extend SystemTap SDT probe argument parser
This patch extends the current generic parser for SystemTap SDT probe
arguments. It can be almost considered a cleanup, but the main point of
it is actually to allow the generic parser to accept multiple prefixes
and suffixes for the its operands (i.e., integers, register names, and
register indirection).
I have chosen to implement this as a list of const strings, and declare
this list as "static" inside each target's method used to initialize
gdbarch.
This patch is actually a preparation for an upcoming patch for ARM,
which implements the support for multiple integer prefixes (as defined
by ARM's asm spec). And AArch64 will also need this, for the same
reason.
This patch was regtested on all architectures that it touches (i.e.,
i386, x86_64, ARM, PPC/PPC64, s390x and IA-64). No regressions were found.

Partial fix for PR breakpoints/10737: Make syscall info be per-arch instead of global
This patch intends to partially fix PR breakpoints/10737, which is
about making the syscall information (for the "catch syscall" command)
be per-arch, instead of global. This is not a full fix because of the
other issues pointed by Pedro here:
<https://sourceware.org/bugzilla/show_bug.cgi?id=10737#c5>
However, I consider it a good step towards the real fix. It will also
help me fix <https://sourceware.org/bugzilla/show_bug.cgi?id=17402>.
What this patch does, basically, is move the "syscalls_info"
struct to gdbarch. Currently, the syscall information is stored in a
global variable inside gdb/xml-syscall.c, which means that there is no
easy way to correlate this info with the current target or
architecture being used, for example. This causes strange behaviors,
because the syscall info is not re-read when the arch changes. For
example, if you put a syscall catchpoint in syscall 5 on i386 (syscall
open), and then load a x86_64 program on GDB and put the same syscall
5 there (fstat on x86_64), you will still see that GDB tells you that
it is catching "open", even though it is not. With this patch, GDB
correctly says that it will be catching fstat syscalls.
(gdb) set architecture i386
The target architecture is assumed to be i386
(gdb) catch syscall 5
Catchpoint 1 (syscall 'open' [5])
(gdb) set architecture i386:x86-64
The target architecture is assumed to be i386:x86-64
(gdb) catch syscall 5
Catchpoint 2 (syscall 'open' [5])
But with the patch:
(gdb) set architecture i386
The target architecture is assumed to be i386
(gdb) catch syscall 5
Catchpoint 1 (syscall 'open' [5])
(gdb) set architecture i386:x86-64
The target architecture is assumed to be i386:x86-64
(gdb) catch syscall 5
Catchpoint 2 (syscall 'fstat' [5])
As I said, there are still some problems on the "catch syscall"
mechanism, because (for example) the user should be able to "catch
syscall open" on i386, and then expect "open" to be caught also on
x86_64. Currently, it doesn't work. I intend to work on this later.

PowerPC64 ELFv2 ABI: skip global entry point code
This patch handles another aspect of the ELFv2 ABI, which unfortunately
requires common code changes.
In ELFv2, functions may provide both a global and a local entry point.
The global entry point (where the function symbol points to) is intended
to be used for function-pointer or cross-module (PLT) calls, and requires
r12 to be set up to the entry point address itself. The local entry
point (which is found at a fixed offset after the global entry point,
as defined by bits in the symbol table entries' st_other field), instead
expects r2 to be set up to the current TOC.
Now, when setting a breakpoint on a function by name, you really want
that breakpoint to trigger either way, no matter whether the function
is called via its local or global entry point. Since the global entry
point will always fall through into the local entry point, the way to
achieve that is to simply set the breakpoint at the local entry point.
One way to do that would be to have prologue parsing skip the code
sequence that makes up the global entry point. Unfortunately, this
does not work reliably, since -for optimized code- GDB these days
will not actuall invoke the prologue parsing code but instead just
set the breakpoint at the symbol address and rely on DWARF being
correct at any point throughout the function ...
Unfortunately, I don't really see any way to express the notion of
local entry points with the current set of gdbarch callbacks.
Thus this patch adds a new callback, skip_entrypoint, that is
somewhat analogous to skip_prologue, but is called every time
GDB needs to determine a function start address, even in those
cases where GDB decides to not call skip_prologue.
As a side effect, the skip_entrypoint implementation on ppc64
does not need to perform any instruction parsing; it can simply
rely on the local entry point flags in the symbol table entry.
With this implemented, two test cases would still fail to set
the breakpoint correctly, but that's because they use the construct:
gdb_test "break *hello"
Now, using "*hello" explicitly instructs GDB to set the breakpoint
at the numerical value of "hello" treated as function pointer, so
it will by definition only hit the global entry point.
I think this behaviour is unavoidable, but acceptable -- most people
do not use this construct, and if they do, they get what they
asked for ...
In one of those two test cases, use of this construct is really
not appropriate. I think this was added way back when as a means
to work around prologue skipping problems on some platforms. These
days that shouldn't really be necessary any more ...
For the other (step-bt), we really want to make sure backtracing
works on the very first instruction of the routine. To enable that
test also on powerpc64le-linux, we can modify the code to call the
test function via function pointer (which makes it use the global
entry point in the ELFv2 ABI).

Partial fix for PR breakpoints/10737: Make syscall info be per-arch instead of global
This patch intends to partially fix PR breakpoints/10737, which is
about making the syscall information (for the "catch syscall" command)
be per-arch, instead of global. This is not a full fix because of the
other issues pointed by Pedro here:
<https://sourceware.org/bugzilla/show_bug.cgi?id=10737#c5>
However, I consider it a good step towards the real fix. It will also
help me fix <https://sourceware.org/bugzilla/show_bug.cgi?id=17402>.
What this patch does, basically, is move the "syscalls_info"
struct to gdbarch. Currently, the syscall information is stored in a
global variable inside gdb/xml-syscall.c, which means that there is no
easy way to correlate this info with the current target or
architecture being used, for example. This causes strange behaviors,
because the syscall info is not re-read when the arch changes. For
example, if you put a syscall catchpoint in syscall 5 on i386 (syscall
open), and then load a x86_64 program on GDB and put the same syscall
5 there (fstat on x86_64), you will still see that GDB tells you that
it is catching "open", even though it is not. With this patch, GDB
correctly says that it will be catching fstat syscalls.
(gdb) set architecture i386
The target architecture is assumed to be i386
(gdb) catch syscall 5
Catchpoint 1 (syscall 'open' [5])
(gdb) set architecture i386:x86-64
The target architecture is assumed to be i386:x86-64
(gdb) catch syscall 5
Catchpoint 2 (syscall 'open' [5])
But with the patch:
(gdb) set architecture i386
The target architecture is assumed to be i386
(gdb) catch syscall 5
Catchpoint 1 (syscall 'open' [5])
(gdb) set architecture i386:x86-64
The target architecture is assumed to be i386:x86-64
(gdb) catch syscall 5
Catchpoint 2 (syscall 'fstat' [5])
As I said, there are still some problems on the "catch syscall"
mechanism, because (for example) the user should be able to "catch
syscall open" on i386, and then expect "open" to be caught also on
x86_64. Currently, it doesn't work. I intend to work on this later.

Replace 'core_regset_sections' by iterator method

capable core file generation support) is replaced by an iterator
method. Overall, this reduces the code a bit, and it allows for more
flexibility.

PR13858 - Can't do displaced stepping with no symbols
Running break-interp.exp with the target always in non-stop mode trips
on PR13858, as enabling non-stop also enables displaced stepping.
The problem is that when GDB doesn't know where the entry point is, it
doesn't know where to put the displaced stepping scratch pad. The
test added by this commit exercises this. Without the fix, we get:
(gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: break *$pc
set displaced-stepping on
(gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: set displaced-stepping on
stepi
0x00000000004005be in ?? ()
Entry point address is not known.
(gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: stepi
p /x $pc
$2 = 0x4005be
(gdb) PASS: gdb.base/step-over-no-symbols.exp: displaced=on: get after PC
FAIL: gdb.base/step-over-no-symbols.exp: displaced=on: advanced
The fix switches all GNU/Linux ports to get the entry point from
AT_ENTRY in the target auxiliary vector instead of from symbols. This
is currently only done by PPC when Cell debugging is enabled, but I
think all archs should be able to do the same. Note that
ppc_linux_displaced_step_location cached the result, I'm guessing to
avoid constantly re-fetching the auxv out of remote targets, but
that's no longer necessary nowadays, as the auxv blob is itself cached
in the inferior object. The ppc_linux_entry_point_addr global is
obviously bad for multi-process too nowadays.
Tested on x86-64 (-m64/-m32), PPC64 (-m64/-m32) and S/390 GNU/Linux.
Yao tested the new test on ARM as well.

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).
