gdb: add back declarations for _initialize functions
6c2659886f
I wrongfully edited gdbarch.c, instead of editing gdbarch.sh and
re-generating gdbarch.c. This patch fixes gdbarch.sh to add a
declaration for _initialize_gdbarch. gdbarch.c is not changed, as the
output of gdbarch.sh now matches the current state of gdbarch.c.
gdb/ChangeLog:
* gdbarch.sh: Add declaration for _initialize_gdbarch.
This removes the two uses of iterate_over_inferiors, in favor of
range-based loops.

(gdbsim_interrupt_inferior): Remove.
(gdbsim_target::interrupt): Replace iterate_over_inferiors use

gdbsim_interrupt_inferior.
While GNU Source Highlight is good, it's also difficult to build and
distribute. For one thing, it needs Boost. For another, it has an
unusual configuration and installation setup.
Pygments, a Python library, doesn't suffer from these issues, and so I
thought it would be a reasonable fallback.
This patch implements this idea. GNU Source Highlight is preferred,
but if it is unavailable (or fails), the extension languages are
tried. This patch also implements support for Pygments.
Something similar could be done for Guile, using:
https://dthompson.us/projects/guile-syntax-highlight.html
However, I don't know enough about Guile internals to make this
happen, so I have not done it here.

While debugging the step-over-syscall problem, i wanted to see a bit more

* aarch64-tdep.c (aarch64_displaced_step_fixup): Add more debugging
output.
In particular, this one:
FAIL: gdb.base/step-over-syscall.exp: fork: displaced=on: check_pc_after_cross_syscall: single step over fork final pc
When ptrace fork event reporting is enabled, GDB gets a PTRACE_EVENT_FORK
event whenever the inferior executes the fork syscall.
Then the logic is that GDB needs to step the inferior yet again in order to
receive a predetermined SIGTRAP, but no execution takes place because the
signal was already queued for delivery. That means the PC should stay the same.
I noticed the aarch64 code is currently adjusting the PC in this situation,
making the inferior skip an instruction without executing it.
The following change checks if we did not execute the instruction
(pc - to == 0), making proper adjustments for such case.
Regression tested on aarch64-linux-gnu on the tryserver.

There's no need (anymore?) to heavily special case this - just make
generic logic consider only its first operand, and deal with the case
of an 'l' suffix not being allowed in a pattern.
Commit b76bc5d54e ("x86: don't default variable shift count insns to
8-bit operand size") pointed out a very bad case, but the underlying
problem is, as mentioned on various occasions, much larger: Silently
selecting a (nowhere documented afaict) certain default operand size
when there's no "sizing" suffix and no suitable register operand(s) is
simply dangerous (for the programmer to make mistakes).
While in Intel syntax mode such mistakes already lead to an error (which
is going to remain that way), AT&T syntax mode now gains warnings in
such cases by default, which can be suppressed or promoted to an error
if so desired by the programmer. Furthermore at least general purpose
insns now consistently have a default applied (alongside the warning
emission), rather than accepting some and refusing others.
No warnings are (as before) to be generated for "DefaultSize" insns as
well as ones acting on selector and other fixed-width values. For
SYSRET, however, the DefaultSize needs to be dropped - it had been
wrongly put there in the first place, as it's unrelated to .code16gcc
(no stack accesses involved).
As set forth as a prereq when I first mentioned this intended change a
few years back, Linux as well as gcc have meanwhile been patched to
avoid (emission of) ambiguous operands (and hence triggering of the new
warning).
Note that I think that in 64-bit mode IRET and far RET would better get
a diagnostic too, as it's reasonably likely that a suffix-less instance
really is meant to be a 64-bit one. But I guess I better make this a
separate follow-on patch.
Note further that floating point operations with integer operands are an
exception for now: They continue to use short (16-bit) operands by
default even in 32- and 64-bit modes.
Finally note that while {,V}PCMPESTR{I,M} would, strictly speaking, also
need to be diagnosed, with their 64-bit forms not being very useful I
think it is better to continue to avoid warning about them (by way of
them carrying IgnoreSize attributes).
Just like other VCVT*{X,Y} templates do, and to allow the programmer
flexibility (might be relevant in particular when heavily macro-izing
code), the two templates should also have Broadcast set, just like their
X/Y-suffix-less counterparts. This in turn requires them to also have
* Dword set on their memory operands, to cover the logic added to
i386gen by 4a1b91eabb ("x86: Expand Broadcast to 3 bits"),
* RegXMM/RegYMM set on their source operands, to satisfy broadcast
sizing logic in gas itself.
Otherwise ATTSyntax templates wouldn't need such operand size attributes.
While extending the test cases, also add Intel syntax broadcast forms
without explicit size specifiers.
This modifies the special __tls_get_addr stub that checks for a
tlsdesc style __tls_index entry and returns early. Not using r11
isn't much benefit at the moment but a followup patch will preserve
regs around the first call to __tls_get_addr when the __tls_index
entry isn't yet set up for an early return.

When running a program with the simulator target, I get:
/home/simark/src/binutils-gdb/gdb/inferior.c:279: internal-error: inferior* find_inferior_pid(process_stratum_target*, int): Assertion `pid != 0' failed.
This can be reproduced by building a GDB for --target=arm-none-gnueabi,
and running with
$ ./gdb -nx --data-directory=data-directory a.out -ex "target sim" -ex load -ex "b main" -ex r
Where a.out is any program with a main.
The problem is that gdbsim_target::wait assumes that inferior_ptid has
the value of the thread it wants to report an event for.
Actually, it's the target's responsibility to come up with the ptid of
the thread the event is for. In the sim target, that ptid is stored in
sim_inferior_data::remote_sim_ptid, so return that instead of
inferior_ptid.
ChangeLog:
* remote-sim.c (gdbsim_target::wait): Return
sim_data->remote_sim_ptid instead of inferior_ptid.
When trying to compile GDB with --target=avr, with gcc 9.2.0, I am

* config.guess (*:Darwin:*:*): Run xcode-select to determine if a
system compiler is installed. If not, do not run set_cc_for_build,
as the default cc will open a dialog box asking to install
Xcode. If no C compiler is available, guess based on uname -p and
uname -m.

Trying to run "make all-gdbsupport" at the top-level in a build from scratch
results in:
make[2]: Entering directory '/home/smarchi/build/binutils-gdb/gdbsupport'
CC agent.o
In file included from /home/smarchi/src/binutils-gdb/gdbsupport/common-defs.h:133,

| ^~~~~~~
Before building all-gdbsupport, we need all-bfd to run, so that bfd.h is
generated.
(Once this patch is merged in the binutils-gdb repo, I'll send it to gcc
to keep the files in sync.)
ChangeLog:
* Makefile.def: Add dependencies of all-gdbsupport on all-bfd.
* Makefile.in: Re-generate.
* objdump.c (jump_info_visualize_address): Discard jumps that are
no longer needed.
(disassemble_bytes): Only compute the maximum level if jumps were
detected.
gdbsupport fails to build with compilers that don't default to C++11
or above. gdbsupport's configure.ac is already using
AX_CXX_COMPILE_STDCXX, which sets CXX_DIALECT to the -std=gnu++11
switch if necessary, but the problem is that nowhere are we using
CXX_DIALECT. This fixes it.

* Makefile.am: Append CXX_DIALECT to CXX.
* Makefile.in: Regenerate.
