25268153a1 Use kinfo_getvmmap on FreeBSD to enumerate memory regions.
Use kinfo_getvmmap from libutil on FreeBSD to enumerate memory
regions in a running process instead of /proc/<pid>/map.  FreeBSD systems
do not mount procfs by default, but kinfo_getvmmap uses a sysctl that
is always available.

Skip memory regions for devices as well as regions an application has
requested to not be dumped via the MAP_NOCORE flag to mmap or
MADV_NOCORE advice to madvise.

	* configure.ac: AC_CHECK_LIB(util, kinfo_getvmmap).
	* configure: Regenerate.
	* config.in: Regenerate.
	* fbsd-nat.c [!HAVE_KINFO_GETVMMAP] (fbsd_read_mapping): Don't
        define.

	enumerate memory regions if present.

07697489f4 Create libiberty.m4, have GDB and GDBserver use it
Converting GDB to be a C++ program, I stumbled on 'basename' issues,
like:

 src/gdb/../include/ansidecl.h:169:64: error: new declaration ‘char* basename(const char*)’
 /usr/include/string.h:597:26: error: ambiguates old declaration ‘const char* basename(const char*)’

which I believe led to this bit in gold's configure.ac:

 dnl We have to check these in C, not C++, because autoconf generates
 dnl tests which have no type information, and current glibc provides
 dnl multiple declarations of functions like basename when compiling
 dnl with C++.
 AC_CHECK_DECLS([basename, ffs, asprintf, vasprintf, snprintf, vsnprintf, strverscmp])

These checks IIUC intend to generate all the HAVE_DECL_FOO symbols
that libiberty.h and ansidecl.h check.

GDB is missing these checks currently, which results in the conflict
shown above.

This adds an m4 file that both GDB and GDBserver's configury use to
pull in the autoconf checks that libiberty clients needs done in order
to use these libiberty.h/ansidecl.h.

cdf436294f Detect 64-bit-ness in PowerPC Book III-E
This patch is to teach both GDB and GDBServer to detect 64-bit inferior
correctly.  We find a problem that GDBServer is unable to detect on a
e5500 core processor.  Current GDBServer assumes that MSR is a 64-bit
register, but MSR is a 32-bit register in Book III-E.  This patch is
to fix this problem by checking the right bit in MSR, in order to handle
both Book III-S and Book III-E.  In order to detect Book III-S and
Book III-E, we check the PPC_FEATURE_BOOKE from the host's HWCAP (by
getauxval on glibc >= 2.16.  If getauxval doesn't exist, we implement
the fallback by parsing /proc/self/auxv), because it should an invariant
on the same machine cross different processes.

In order to share code, I add nat/ppc-linux.c for both GDB and
GDBserver side.

In the end I have managed to test it by Wine myself:

Could not load libcc1.so: Module not found.

Even if it managed to load libcc1.so (it needs host-dependent name libcc1.dll)
then it would soon end up at least on:

default_infcall_mmap:
  error (_("This target does not support inferior memory allocation by mmap."));

As currently there is only:

linux-tdep.c:
  set_gdbarch_infcall_mmap (gdbarch, linux_infcall_mmap);

While one could debug Linux targets from MS-Windows host I find it somehow
overcomplicated now when we are trying to get it running at least on native
Linux x86*.

The 'compile' project needs a larger port effort to run on MS-Windows.

92d8d229d9 Fix for PR 17247: Block SIGCHLD while initializing Guile.
The problem here is that if a thread other than gdb's main thread
gets a SIGCHLD (it's an asynchronous signal so the kernel will
essentially pick a random thread) then gdb will hang if it is
in sigsuspend when the SIGCHLD is delivered.  The other thread
will see the signal and the sigsuspend won't "wake up".

Guile and libgc should be blocking SIGCHLD in their threads,
but we need to work with Guile 2.0 and libgc 7.4.
The problem first shows up in libgc 7.4 because it is the first
release that enables multiple marker threads by default.

	PR 17247
	* guile.c: #include <signal.h>.

74edf51613 PR 17185
PR 17185 describes a problem with using gdb+guile with libgc 7.4.0.
The symptom is a hang in sigsuspend.
[The thread referenced in the PR has the details.]

This patch applies the same workaround Guile has applied.
There is no functionality or real performance loss with this,
and Guile has been using it for awhile.

This commit wraps calls to the demangler with a segmentation fault
handler.  The first time a segmentation fault is caught a core file

choice to exit or to continue their GDB session.  A maintainence
option is provided to allow the user to disable the crash handler
if required.

161d1bec16 don't check for stddef.h
gdb already unconditionally includes stddef.h in many places.
I think there is no reason to check for its existence.

Also, Zack Weinberg's header file survey agrees:

    http://hacks.owlfolio.org/header-survey/

This patch removes the configure check and the inclusion guards.
It also removes a redundant inclusion that I noticed in defs.h.

9467110bae gdb configure updates
Now that the configury needed for the "common" and "target"
directories is in common.m4, some code in gdb's configure.ac is
redundant.

I ran this script after making an "ID" file using mkid:

   sed -n 's/^.*\(HAVE_[A-Z0-9_]*\).*$/\1/p' config.in |
   while read x; do
     echo ===== $x
     gid $x | egrep -v '^(testsuite|gnulib|common|target|gdbserver)/'
   done

This finds all the spots using HAVE_ defines, and, more importantly,
makes it clear which defines aren't used in the main parts of gdb.

From this I came up with this patch to remove all the unused bits.

There are a few that are subtly used -- for example the configure
script sometimes checks internal configure cache variables, meaning
some checks cannot be removed.

e655c1a2f5 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.

 ../../src/gdb/common/filestuff.c:38:24: fatal error: sys/socket.h: No such file or directory

There are no sockets on djgpp.  This #ifdef's out the bits in the file
that use sockets, depending on whether winsock or sys/socket.h is
available.

As alternative approach, given ser-tcp.c, ser-pipe.c, etc. are split
into separate files, and which to use is selected by configure.ac:

 dnl Figure out which of the many generic ser-*.c files the _host_ supports.
 SER_HARDWIRE="ser-base.o ser-unix.o ser-pipe.o ser-tcp.o"
 case ${host} in
  *go32* ) SER_HARDWIRE=ser-go32.o ;;
  *djgpp* ) SER_HARDWIRE=ser-go32.o ;;
  *mingw32*) SER_HARDWIRE="ser-base.o ser-tcp.o ser-mingw.o" ;;
 esac
 AC_SUBST(SER_HARDWIRE)

... I considered splitting filestuff.c similarly.  But I quickly gave
up on the idea, as it looked like a lot more complication over this
approach, for no real gain.  Plus, there are uses of these functions
outside the ser*.c framework.

gdbserver's configure.ac is already checking for sys/socket.h.
