This commit does most of the mechanical removal. IOW, the easy part.
procfs.c isn't touched beyond removing a couple obvious bits that are
guarded by a couple macros defined in config/alpha/nm-osf3.h. Going
beyond that for procfs.c & co would be a harder excision that
potentially affects Solaris.
Some comments in the generic alpha code ABIs that may still be
relevant and I wouldn't know what to do with them. That can always be
done on a separate pass, preferably by someone who can test on alpha.
A couple other spots have references to OSF/Tru64 and related files
being removed, but it felt like removing them would make things worse,
not better. We can revisit those when we next need to touch that
code.
I didn't remove a reference to osf in testsuite/lib/future.exp, as I
believe that code is imported from DejaGNU.

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.

This patch is to fix the build error when GDB is configured as:

This patch adds one line of code in configure test to use local

Note that we append -Werror to CFLAGS to catch the warning related to
assignment to scope. See more in this thread

The goal of this patch is to provide an easy way to make
--disable-werror the default when building binutils, or the parts
of binutils that need to get built when building GDB. In development
mode, we want to continue making -Werror the default with GCC.
But, when making releases, I think we want to make it as easy as
possible for regular users to successfully build from sources.
GDB already has this kind of feature to turn -Werror as well as
the use of the libmcheck library. As GDB Release Manager, I take
advantage of it to turn those off after having cut the branch.
I'd like to be able to do the same for the binutils bits. And
perhaps Tristan will want to do the same for his releases too
(not sure, binutils builders might be a little savvier than GDB
builders).
This patch introduces a new file, called development.sh, which
just sets a variable called $development. In our development branches
(Eg. "master"), it's set to true. But setting it to false would allow
us to change the default behavior of various development-related
features to be turned off; in this case, it turns off the use of
-Werror by default (use --enable-werror to turn it back on).

Tested on x86_64-linux by building two ways: One with DEVELOPMENT
set to true, and one with DEVELOPMENT set to false. In the first
case, I could see the use of -Werror, while it disappeared in
the second case.

An earlier patch removed the check for "syscall" since the results
were not used in the C code. However, the result was used, via the
cache variable, elsewhere in configure.
This patch fixes the problem by checking for "syscall" at the point at
which HAVE_TKILL_SYSCALL is defined.
2013-11-11 Tom Tromey <tromey@redhat.com>
* config.in, configure: Rebuild.
* configure.ac (HAVE_TKILL_SYSCALL): Check for "syscall".
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.
2013-11-08 Tom Tromey <tromey@redhat.com>
* configure, config.in: Rebuild.
* configure.ac: Remove unused configury.
The removal of solib-sunos.c also removed the last user of various

This patch removes the corresponding configure code.

* configure, config.in: Rebuild.
* configure.ac: Remove all link.h-related checks.
It has bothered me for a while that files in common/ use macros
defined via autoconf checks, but rely on each configure.ac doing the
proper checks independently.
This patch introduces common/common.m4 which consolidates the checks
assumed by code in common.
The rule I propose is that if something is needed or used by common,
it should be checked for by common.m4. However, if the check is also
needed by gdb or gdbserver, then it should be duplicated there.
Built and regtested on x86-64 Fedora 18 (though this is hardly the
most strenuous case) and using the Fedora 18 mingw cross compilers. I
also examined the config.in diffs to ensure that symbols did not go
missing.

This factors --enable-libmcheck related bits from GDB's configure.ac
and makes GDBserver use them too. Specifically, the 'development'
global is moved to a separate script to it can be sourced by both GDB
and GDBserver, and the --enable-libmcheck/--disable-libmcheck bits
proper are moved to a new m4 file.
I started out by defining 'development' in the m4 file, but in the end
decided against it, as a separate script has the advantage that
changing it in release branches does not require regenerating
configure, unlike today.
I had also started out by making the new GDB_AC_LIBMCHECK itself
handle the yes/no default fallback depending on release/developement,
but since I had split out 'development' to a separate script, and, GDB
needs the python checks anyway (hence we'd need to do the python
checks in gdb's configure.ac, and pass in a 'default lmcheck yes/no'
parameter to GDB_AC_LIBMCHECK anyway), I ended up keeping
GDB_AC_LIBMCHECK isolated from the 'development' global. IOW, it's
the caller's business to handle it.
Tested on x86_64 Fedora 17. Built GDB and GDBserver with and without
--enable-libmcheck, and observed --enable-libmcheck overrides the
disablement of -lmcheck caused by python supporting threads, and that
GDBserver links with -lmcheck when expected. Also observed that
changing the 'development' global, and issuing "make" triggers a
relink, and '-lmcheck' is included or not from the link accordingly.

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.

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 ;;

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.

The routines in sparc-sol-thread used to be SPARC-specific (and
documented as such in the ptrace man page), and therefore hosting them
in a sparc-specific file made sense. However, newer versions of
Solaris now use those callbacks (Solaris 10 Update 10, apparently),
and thus the note about these callbacks being specific to SPARC
was removed.
So this patch deletes sparc-sol-thread.c and moves the code back

The problem showed up on AIX when we switched from the system linker
to GNU ld. What happens is that configure is adding -lpthdebug to
CONFIG_LDFLAGS when AIX thread debugging support is detected. But
this causes the "-lpthread" switch to be placed at the _before_
GDB's .o files (see Makefile.in):
INTERNAL_LDFLAGS = [...] $(CONFIG_LDFLAGS)
[...]
gdb$(EXEEXT): gdb.o $(LIBGDB_OBS) $(ADD_DEPS) $(CDEPS) $(TDEPLIBS)
rm -f gdb$(EXEEXT)
$(CC_LD) $(INTERNAL_LDFLAGS) $(WIN32LDAPP) \
-o gdb$(EXEEXT) gdb.o $(LIBGDB_OBS) \
$(TDEPLIBS) $(TUI_LIBRARY) $(CLIBS) $(LOADLIBES)
And as a result of this, the linker reports an error due to some
symbols in aix-thread.o not being satisfied.
This patch adds the "-lpthread" switch to LIBS instead, which should
be the right place to add it.
