[NEWS] powerpc-lynxos gdbserver support

This adds an entry in the NEWS file announcing the GDBserver support
on powerpc-lynxos.

gdb/ChangeLog:

        * NEWS: Add entry announcing GDBserver support on powerpc-lynxos.

   * mi/mi-main.c (mi_cmd_list_target_features): Add `reverse'
       as a feature reported by -list-target-features.

       * gdb.texinfo (GDB/MI Miscellaneous Commands): Document new
       feature `reverse' output by -list-target-features.

gdbserver support for powerpc-lynxos (4.x)

This patch adds support for powerpc-lynxos.

gdbserver/ChangeLog:

        * gdbserver/lynx-low.c, gdbserver/lynx-low.h,
        gdbserver/lynx-ppc-low.c: New files.
        * Makefile.in (lynx_low_h): New variable.
        (lynx-low.o, lynx-ppc-low.o): New rules.
        * configure.ac: On LynxOS, link with -lnetinet.
        * configure.srv: Add handling of powerpc-*-lynxos* targets.
        * configure: regenerate.

Import vsnprintf from libiberty if not available.

vasprintf and vsnprintf are not available on LynxOS, at least not on
version 4.0.0.  This patch updates the configury to import them from
libiberty if not available out of the box.

gdbserver/
        * Makefile.in (vasprintf.o, vsnprintf.o): New rules.
        * configure.ac: Add check for vasprintf and vsnprintf.
        * configure, config.in: Regenerate.
        * server.h (vasprintf, vsnprintf): Add conditional declarations.

Generate regformats/rs6000/powerpc-32.dat

I will need this description for the ppc-lynxos debugger where, AFAICT,
we only have access to the core GP and FP registers.  So this adds
powerpc-32 to the list of targets for which a .dat file needs  to be
generated.

2010-04-30  Joel Brobecker  <brobecker@adacore.com>

        * features/Makefile (WHICH): Add rs6000/powerpc-32.
        (powerpc-32.o, powerpc-32.c): New rules.
        (clean): Also remove powerpc-32.c.
        * regformats/rs6000/powerpc-32.dat: Generate.

[gdbserver] Move malloc.h include to server.h.

This patch moves all includes of malloc.h, which were introduced
purely to get access to alloca's declaration, to server.h, next
to the include of alloca.h.

There is one exception: gdbreplay.c, which does not include server.h.
In this case, the include of alloca.h was simply moved up a bit, next
to the include of malloc.h.

gdb/gdbserver/ChangeLog:

        * gdbreplay.c: Move include of alloca.h up, next to include of
        malloc.h.
        * server.h: Add include of malloc.h.
        * mem-break.c: Remove include of malloc.h.
        * server.c, tracepoint.c, utils.c, win32-low.c: Likewise.

Put ChangeLog entries in the right ChangeLog file.

* netbsd-core.c (netbsd_core_core_file_pid): Renamed to ...
(netbsd_core_file_pid): ... this.

Fix typo

    * ld-scripts/section-match.exp: New file.  Runs ths
        section-match-1 test.
        * ld-scripts/section-match-1.d: New file.
        * ld-scripts/section-match-1.s: New file.
        * ld-scripts/section-match-1.t: New file.

2010-09-01  Tristan Gingold  <gingold@adacore.com>

* coffcode.h (coff_slurp_line_table): Add a cast.
(coff_slurp_reloc_table): Ditto.

Compile memmem.o without -Werror.

This reproduces the same approach as in GDB to allow us to build
specific files without -Werror.

gdb/gdbserver/ChangeLog:

        * Makefile.in (INTERNAL_CFLAGS_BASE): New variable. Extracted
        from INTERNAL_CFLAGS.
        (INTERNAL_WARN_CFLAGS): New variable.
        (INTERNAL_CFLAGS): Adjust, using INTERNAL_WARN_CFLAGS.

use xsnprintf instead of snprintf.

snprintf is not available on LynxOS, so I changed the calls to snprintf
to calls to xsnprintf, which should be strictly equivalent.

gdb/gdbserver/ChangeLog:

        * utils.c (xsnprintf): Make non-static.
        * server.h: Add xsnprintf declaration.
        * linux-low.c, nto-low.c, target.c, thread-db.c, tracepoint.c:
        replace calls to snprintf by calls to xsnprintf throughout.

include alloca.h if available.

On LynxOS, alloca is defined in allocal.h.  This fixes one warning that
occurs when building GDBserver for LynxOS.

gdb/gdbserver/ChangeLog:

        * configure.ac: Add configure check for alloca.
        * configure, config.in: Regenerate.
        * server.h: Include alloca.h if it exists.
        * gdbreplay.c: Include alloca.h if it exists.
