Import the "pathmax" gnulib module.

This imports the "pathmax" gnulib module, making PATH_MAX always
available on systems that have the notion of a constant max path limit
(i.e., practically everywhere except the Hurd), along with fixing a
couple broken systems --- see pathmax.h in the patch.

This means we can normalize on PATH_MAX throughout the tree (instead
of some places using MAXPATHLEN, or defining fallback constants
ourselves).

This is the just the importing step.

Reimplement DJGPP's .gdbinit -> gdb.ini renaming.

This simplifies the .gdbinit filename selection logic.

We have a GDBINIT_FILENAME define that supposedly configurations would
override, but none do so.  Instead, the only configuration that wants
a different file name instead of ".gdbinit", djgpp, does a strcpy over
the gdbinit global array.  This means the array needs to be sized, and
the code that does that is doing the usual
'PATH_MAX/FILENAME_MAX/fallback constant/etc.' mess.

Instead of all that, it's much simpler to have configure specificy the
.gdbinit filename.  As bonus, we can then make the "gdbinit" global
array const.

A following patch will want to make the "gdbinit" global array const.
As usual, that forces in a cascading series of const additions.  This
patch preemptively does those.  I went all the way up to constifying
catch_command_errors, but then that would require constifying
execute_command as well (which is a much more significant effort).  So
as stop point, I found the cleanest would be to add a variant of
catch_command_errors that takes const args, and use that in the few
spots that needed it due to the the get_init_files constification.

Rely on gnulib's unistd.h replacement.

With gnulib's unistd module, we can assume unistd.h is always present, and that

Don't remove unistd.h from GDB's configure.ac, as later tests in the

Import the "unistd" gnulib module.

I wanted to import the pathmax module, and that pulls in the unistd
module as dependency.  The unistd module is actually bigger than the
pathmax module.  If we're going to end up with it, might as well
import it explicitly, and make use of it throughout.

The "unistd" module makes a GNU-like <unistd.h> always available.
This means we no longer need to do:

 +#ifdef HAVE_UNISTD_H
  #include <unistd.h>
 +#endif

and we can remove a few constants from defs.h.

utils.c: pathconf call, check for _PC_PATH_MAX instead of HAVE_UNISTD_H.

This check in utils.c for HAVE_UNISTD_H is being used as proxy for
"HAVE_PATHCONF", as pathconf is supposed to be declared in unistd.h.

It's possible that there are systems out there that have realpath,
unistd.h and alloca, but not pathconf+_PC_PATH_MAX.  I don't know of
any by heart, but if we import gnulib's unistd module (which a
following patch will do), then unistd.h ends up always available, so
the check ends up incorrect.  As pathconf is being called with

Reimport gnulib from scratch.

Moving aside gnulib/import/, and re-running our
gnulib/update-gnulib.sh script, surprisingly, one gets a different
result compared to what's in the tree.  This is with pristine FSF
autoconf and FSF automake, at the versions required by
update-gnulib.sh.  However, if one just runs the update-gnulib.sh
scripts against the _existing_ tree, then nothing changes...  I
suspect gnulib-tool's merge logic might be preserving some things by
design.  This gets rid of cruft that might have accumulated over

This patch implements the support for SystemTap SDT probes on IA-64.

Joel Brobecker reported a bug which was happening because of the
"Improved linker-debugger interface", by Gary Benson, when tested on
IA-64 with rhES5.  The message is:

<http://sourceware.org/ml/gdb-patches/2013-06/msg00745.html>

The failure happened because GDB was trying to parse the probes'
operands using only the generic parser (implemented on stap-probe.c),
because the arch-specific parser was not implemented.  Thus, I am
committing the following changes which solve the bug.

Move comment on the 'stepping over resolver' mechanism to the internals manual.

This whole comment is now a bit out of place.  I looked into moving it
to handle_inferior_event, close to where in_solib_dynsym_resolve_code
is used, but then there are 3 such places.  I then looked at
fragmenting it, pushing bits closer to the definitions of
in_solib_dynsym_resolve_code and gdbarch_skip_solib_resolver, but then
we'd lose the main advantage which is the overview.  In the end, I
realized this can fit nicely as internals manual material.

don't keep a gdb-specific date

Right now there are two nightly commits to update a file in the tree
with the current date.  One commit is for BFD, one is for gdb.

It seems unnecessary to me to do this twice.  We can make do with a
single such commit.

This patch changes gdb in a minimal way to reuse the BFD date -- it
extracts it from bfd/version.h and changes version.in to use the
placeholder string "DATE" for those times when a date is wanted.

I propose removing the cron job that updates the version on trunk, and
then check in this patch.

For release branches, we can keep the cron job, but just tell it to
rewrite bfd/version.h.  I believe this is a simple change in the
crontab -- the script will work just fine on this file.

This also moves version.in and version.h into common/, to reflect
their shared status; and updates gdbserver to use version.h besides.

* common/create-version.sh: New file.

sim: bfin: note missing parallel handling of SEARCH

The SEARCH insn is an oddball when it comes to parallel usage.  It places a
big limit on what other insns it can run in parallel with, but we don't
currently track the amount of state needed to verify this (since no other insn
really requires this).  Add a note for now in case we get around to it.

sim: bfin: handle invalid HLs encoding in dsp shift insns

For many of the 32bit dsp shift related insns, we were just ignoring the HLs
field.  The hardware does not though and will reject the insn if it's set
incorrectly.  Update the sim to match.

sim: bfin: run-tests.sh: fix typo in usage exit

sim: bfin: se_all32bitopcodes: skip debug insns under the sim

Since the sim has a few fake debug insns that the hardware does not, we
need to check for those before attempting to run them.  Otherwise we'll
randomly trigger the sim debug asserts/aborts/halts insns.  On the
hardware, these are proper invalid insns, and the table catches that.

sim: bfin: speed up all insn testcases slightly

The main body of the "all insn" test is executed once per tested insn, and
we test millions of insns here.  Any shrinkage we can do in this loop will
speed things up nicely (since it's multiplied per tested insn).

To that end, simplify the end-of-table test into one less insn, and omit
the SSYNC when we build for the sim.  When we build to run on the hardware,
this insn matters, but the sim doesn't have write store buffers in the chip
that might get in the way (memory writes are atomic).
