errors when hitting breakpoints during inferior function calls
in 64-bit programs.
(fix_sign_extension): Make public, rename to mips_addr_bits_remove.

"i*86-*-linux" for "signal SIGUSR1". Now works, at least with
RedHat 4.0.
* gdb.threads/pthreads.c (_MIT_POSIX_THREADS): Define if target is
linux. This allows the test case to at least compile on latest
linux, but still not run due to missing the threads runtime library.
directory to search gdb directory. Accept and step over conditional
stack alignment code. Consume $prompt in failure cases.
Reset timeout to $oldtimeout instead of some arbitrary value.

doing cross compiles.

(xgcc): Set variable to full path of gcc in build tree. Use findfile
to verify that gcc exists in build tree, and if so set CC to that
gcc and to use B_OPTIONS and TARGET_INCLUDES.

(REGISTER_VIRTUAL_TYPE): Modified for PC_REGNUM and SP_REGNUM.
(REGISTER_CONVERTIBLE): Make PC and SP convertible.

virtual buf instead of the raw buf. Needed for REGISTER_CONVERT
to work with non-floating point regs.

information, then the end of the prologue should the first
assembly instruction of the first source line.
* values.c (value_from_longest): Put in D10V call to
fix up address pointers.
* config/d10v/tm-d10v.h (REGISTER_VIRTUAL_SIZE): Modified.
(REGISTER_VIRTUAL_TYPE): Modified for PC_REGNUM and SP_REGNUM.
(REGISTER_CONVERTIBLE): Make PC and SP convertible.
(REGISTER_CONVERT_TO_VIRTUAL): Define.
(REGISTER_CONVERT_TO_RAW): Define.
(D10V_MAKE_DADDR): Define.

by restarting the poll.

returns its argument unchanged.

of PIDGET and fold both alternatives into common code.
(pass_signal): Use PIDGET for pid passed to kill().
* sh-tdep.c: Add functionality for target function calls.
* config/sh/tm-sh.h: Add support for target function calls.
This is a safety check-in: everything works, and there'll be another
clean-up round shortly.

* m32r-tdep.c: Add functionality for target function calls.
* valops.c: Small change to support target function calls.
* config/m32r/tm-m32r.h: Add support for target function calls.
This is a safety checkin -- everything works, but there'll be another
clean-up round later.
* defs.h: modify Nov 11 12:59:00 change so _MSC_VER is checked
instead of _WIN32
* win32-nat.c: fix Nov 11 12:59:00 change (windows.h should
be included instead of windefs.h for compilers other than
VC++).
* mswin/windefs.h: remove ^Ms and change C++ style comments
to C style comments
* mips-tdep.c (get_frame_pointer, fix_sign_extension):
New functions to consolidate common code.
(mips_frame_chain, init_extra_frame_info): Use new functions
to fix problems with backtrace and finish commands on ddb board.

tests and anonymous union print/ptype tests.
* gdb.base/list.exp (test_forward-search): Increase timeout by
5 minutes for the "search extremely long line" case.
* lib/gdb.exp (gdb_test): Document that the third arg to gdb_test is
completely optional and that the pass/fail messages use the command as
the message if that third arg is a null string.
(gdb_test_exact): Arrange that a null string pattern means match a
null string output rather than any output, which might include random
errors.
* gdb.base/mips_pro.exp: Add "mips*-sgi-irix4*" xfail for
backtrace test.
* gdb.c++/demangle.exp: Add a "*-*-*" xfail for test that was
always failing and failure is now exposed by gdb.exp changes.
"call king(a, otto[[10, 15], [20, 25]])".
* pr-8742.exp: Add mips*-sgi-irix* xfails for
"pass int powerset tuple"
"pass set powerset tuple"
"pass modeless int powerset tuple" and
"pass modeless set powerset tuple".
* tuples.exp: Add sparc-*-solaris* and sparc-*-sunos*
xfails for several "set var" commands that are failing.
Convert most of the set commands into gdb_test_exact
commands.
if we encounter a positive stack adjustment.
(find_proc_desc): If heuristic_fence_post is non-zero, use
heuristic_proc_start to determine the start of a function before
calling heuristic_proc_desc.

for C_LABEL symbols from mst_* to mst_file_*.

clear the recently added header_files fields.
(dbx_symfile_finish): Free hfiles[i].vector to avoid storage leak.
* d10v-tdep.c: Fix some problems with inferior function calls.
* config/d10v/tm-d10v.h (EXTRA_FRAME_INFO): Change dummy to be
a pointer to the dummy's stack instead of just a flag.
