know that the task is dead.
1999-12-13 Mark Kettenis <kettenis@gnu.org>

instead of directly from the kernel. Add some hackery to make
sure that the info isn't influenced by suspension of the task in
the proc server itself.

CONFIG_INITS list. This caused problems with init.c, because
sol-thread.c would be grepped twice for _initialize_* functions.

* Makefile.in: Add FIXME for init.c.
* bcache.h, bcache.c, c-valprint.c, coffread.c, stabsread.c,
stack.c, valprint.c: Change variables to unsigned.

* c-lang.c, ch-lang.c, f-lang.c, m2-lang.c: Include valprint.h
rather than declaring print_max and repeat_count_threashold
ourselves (incorrectly).
* valprint.h: Do declare repeat_count_threashold.
* ch-exp.c: Use default case for internal error.
* findvar.c: Don't omit argument type.
* symtab.c: Remove unused variable.
* configure.host, configure.tgt: Comment out Gould configs.
* Makefile.in: Comment out Gould-related actions.
* gould-xdep.c, gould-tdep.c, config/gould/*: Comment out.

And the first one bites the dust...
* gnu-regex.c: Check ENABLE_NLS instead of HAVE_LIBINTL_H.
* configure.in: Don't check for libintl.h.
* configure, config.in: Regenerated.
Fixes a problem on debian systems, a conflict between the
/usr/include/libintl.h and the routines that are actually linked in,
up in ../intl.
static globals for dealing with binary transmissions.
(remote_write_bytes): Add support for binary downloads
by shadowing the "M" packet with a new "X" packet. This

Get rid of ifdef'ed out code.
(scan_procs): Get rid of ifdef'ed out code.
* somread.c (som_symfile_read): Coerce first argument passed to
make_cleanup to the correct type.
* hp-psymtab-read.c (do_pxdb): New function. Check whether the
file needs to be processed by pxdb (an HP debug info massaging
tool), if so call it.
(hpread_build_psymtabs): Initialize scan_start to 0 and
simplify flow of control.
* somread.c (som_symfile_read): Add call to do_pxdb (),
in hp-psymtab-read.c.
* symfile.c (symbol_file_add): Remove ifdef'ed out HPUX specific
code.
(symfile_bfd_open): Remove HPUXHPPA ifdef'ed code. Code is now
in hp-psymtab-read.c.
* i386-stub.c, m32r-stub.c, m68k-stub.c, sh-stub.c, sparc-stub.c,
sparcl-stub, sparclet-stub.c: Change declaration of putDebugChar
to include explicit void return type as per documentation. Fix up
occasions where stubs erroneously checked return type.

memory_changed_hook to inform UIs that the user has changed
the target's registers/memory.

number of arguments. Reformat whitespace.
As far as I can tell, the func command (only enabled in --dbx mode) doesn't
actually work right now, even with this rather glaring fix. I'm not going
to spend time on it; dbx mode looks pretty seriously broken after a five
second glance.

variable.
* breakpoint.c (bpstat_stop_status): Handle systems where

instead of the magic number "42000". (remote_find_new_threads):
if inferior_pid is unknown, get and use the current thread id.
(remote_start_remote): on connecting, attempt to get the current
thread id for inferior_pid. (remote_resume): If pid == -1,
then resume any-thread (not the current thread specifically).
* thread.c (info_threads_command): don't initialize current_pid
until after call to FIND_NEW_THREADS (which may change inferior_pid).
* utils.c: <readline/readline.h> instead of "readline/readline.h".
* configure.in (TERM_LIB): Search for the appropriate term library
on the host system.
* configure: Regenerated.
* Makefile.in (TERMCAP): Set based on autoconf check.
* config/*/*.mh: Don't override TERMCAP setting.
than $(READLINE_SRC) so #include <readline/readline.h> will work.
* top.c: #include <readline/history.h> instead of "history.h".
* tracepoint.c: Likewise.
* mac-xdep.c: Likewise.

is null, ensure that saved registers are copied from the local
variable that was used to obtain them.

Convert mn10300 and PPC targets.
Add two pointers (saved_regs, extra_info) to struct frame_info.
Introduce new macro FRAME_INIT_SAVED_REGS which replaces
FRAME_FIND_SAVED_REGS.
Document.
Use in mn10300 and rs6000 targets. Fix side effects on ALPHA, MIPS,
Z8K and SPARC targets.
* configure.in (with-sim-gpu2): Do not emit a -L argument without
an associated pathname. Link in the math library after the gpu2
library.
Assumes that libm is around (and doesn't take advantage of the
AC_CHECK_LIB(m) that is already in configure.in), but this is a
minor point and unlikely to cause problems.

Merged in m68k-linux patch from Andreas Schwab
1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>

* gdb/m68klinux-nat.c: New file.
* gdbserver/low-linux.c: Add support for m68k-linux.
* gdb/config/m68k/tm-m68k.h (NUM_FREGS): New macro.
* config/m68k/tm-m68k.h (NUM_FREGS): m68k-linux patch.
Added NUM_FREGS macro.
* config/m68k/xm-linux.h: m68k-linux patch. New file.
* config/m68k/tm-linux.h: m68k-linux patch. New file.
* config/m68k/nm-linux.h: m68k-linux patch. New file.
* config/m68k/linux.mt: m68k-linux patch. New file.
* config/m68k/linux.mh: m68k-linux patch. New file.
* gdbserver/low-linux.c: m68k-linux patch. Added an ifdef
that checks the value of __GLIBC to decide whether or
not to include sys/reg.h.
* m68klinux-nat.c: m68k-linux patch. New file. Note
both m68k-tdep.c and m68klinux-nat.c contain definitions
for supply_gregset and supply_fpregset. The definitions
in m68k-tdep.c are valid is USE_PROC_FS is defined. Otherwise,
the definitions in m68klinux-nat.c will be used. This is a
bit of a hack. The supply_* routines do not belong in
*_tdep.c files. But, there are several lynx ports that currently
depend on these definitions.
* configure.tgt: m68k-linux patch. Added m68*-*-linux*
gdb_target.
* configure.host: m68k-linux patch. Added m68*-*-linux*
gdb_host.

m68klinux-nat.o
* config/i386/xm-cygwin.h: Remove REQUEST_QUIT definition.
* config/powerpc/xm-cygwin.h: Ditto.
PR 17664.
With this define in place, you can't type "q" to get out of GDB's pager
under Cygwin.
* monitor.c (monitor_read_memory): Zero out pattern buffers
before calling re_search.
(parse_register_dump): Ditto.
PR 18049. This bug had existed erratically since I upgraded to
the new gnu-regex.c this last summer. The problem is mostly in
parse_register_dump; the allocated structure has some random values
in it and there is a flag set in the register_pattern structure by the
gnu-regex library which indicates that the values in the re_registers
should be trusted.
If those arbitrary contents aren't zero, gnu-regex tries to run realloc
on them and we get a core dump on some hosts for some targets when the
moon is just right.
* m32r-tdep.c (decode_prologue): If no branch or push fp is found,
but there's a stack adjust, then use that as the end of prologue.
(m32r_skip_prologue): don't skip past the first line if there is
line info. (m32r_virtual_frame_pointer): new function.
(m32r_fix_call_dummy): no return value needed.

TARGET_VIRTUAL_FRAME_POINTER from here to target.h.
* target.h: Add default definition of TARGET_VIRTUAL_FRAME_POINTER.
* ax-gdb.c (gen_frame_args_address, gen_frame_locals_address):
use TARGET_VIRTUAL_FRAME_POINTER to determine frame pointer.
(gen_trace_for_expr): new argument, address of tracepoint,
gets passed to new_agent_expr and added to struct agent_expr.
(is_nontrivial_conversion): call to new_agent_expr now requires
a dummy argument. (agent_command): use get_current_frame() to
get current PC scope; pass it to gen_trace_for_expr.
* ax-general.c (new_agent_expr): new argument, address of
tracepoint; store it in new field of struct agent_expr.
* ax.h (struct agent_expr): add new field for tracepoint address.
* ax-gdb.h: change prototypes to match above changes.
Convert mn10300, MIPS and powerpc/rs6000 targets to use
BREAKPOINT_FROM_PC
Delete global variable memory_breakpoint_size. Use BREAKPOINT_FROM_PC
instead.
* symfile.c (deduce_language_from_filename): rewrite so as to
work from a table of filename extensions, modifiable by the user.
(filename_language_table): new data structure.
(set_ext_lang_command): new function for new command, "set
extension-language". (info_extension_language_command): new
function for new command "info extension-languages".
(add_filename_language, init_filename_language_table): new
support functions for the above.
* language.c (language_enum): new function. Support for above.
* coffread.c (coff_symtab_read): Discard C_LABEL's that are not
function entry points, to avoid getting them in the stack dump
instead of the actual function.
without NAT_FILE definition, configure will assume that GDB cannot
run native.
* config/m68k/nm-delta68.h (KERNEL_U_SIZE): New macro.
* delta68-nat.c (kernel_u_size): New function.
