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

See http://sourceware.org/ml/gdb/2010-07/msg00118.html for
a description of the problem. Namely, the file and fullname
fields are inverted in the output of the -file-list-exec-source-files
GDB/MI command:
(gdb) interpreter-exec mi -file-list-exec-source-files
^done,files=[{file="/takamaka.a/brobecke/ex/list-exec-source-files/foo.c",fullname="foo.c"},{file="/takamaka.a/brobecke/ex/list-exec-source-files/foo.c",fullname="foo.c"},{file="",fullname="init.c"},{file="",fullname="../sysdeps/x86_64/elf/start.S"},{file="",fullname="../sysdeps/x86_64/elf/start.S"}]
It turns out to be a silly thinko: The map_symbol_filenames function
calls the psymtab version of map_symbol_filenames routine, and this
version called the callback function with filename and fullname
in the wrong order (fullname/filename instead of filename/fullname).
The routine description in symfile.h confirst that expected order for
the FUN callback parameters:
/* Call a callback for every file defined in OBJFILE. FUN is the
callback. It is passed the file's name, the file's full name,
and the DATA passed to this function. */
void (*map_symbol_filenames) (struct objfile *objfile,
void (*fun) (const char *, const char *,
void *),
void *data);
Fixing this error uncovered another location where the arguments
were reversed: maybe_add_partial_symtab_filename. Once the first
error was fixed, the debugger would crash while attempting to do
completion, because it was given a NULL fullname instead of the
non-NULL filename.
