* remote-rdp.c (rdp_init): Don't discard first character on reset.
(translate_open_mode): Define table.
(exec_swi): Handle SWI_Clock. SWI_Open now handles stdin/stdout.
SWI_Write returns number of bytes not written. SWI_Read does the
same. SWI_Seek should return success/failure flag. Fix SWI_Flen.
A patch from PR 15841 for the RDP (Demon) interface.
a printable representation.
(monitor_error): Call error after converting string into printable
format.
(monitor_printf{,_noecho}): If EXTRA_RDEBUG is defined, convert string
into printable form before printing.
(monitor_expect): Ditto.
(monitor_read_memory{,_single}): Call monitor_error, not error.
(monitor_read_memory): Return immediately if length is 0.
* ppcbug-rom.c (init_ppc_cmds): Fill in dump_registers field, which is
now required.
Re-do TARGET_PRINT_INSN_INFO, TARGET_PRINT_INSN, TARGET_ARCHITECTURE,
TARGET_ARCHITECTURE_AUTO, TARGET_BYTE_ORDER_SELECTABLE_P,
TARGET_BYTE_ORDER so that they can all be overriden.
Document.
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.

must accept a signal number as parameter.

`char'.
* findvar.c (register_valid): Ditto.
* defs.h (make_cleanup_func): Protect parameter list by `PARAMS'.
* gdbthread.h (unbind_target_thread_vector): Likewise.
Merged in m68k-linux patch from Andreas Schwab
1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>

* 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

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.
* tracepoint.c: Move default definition of
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.
* rdi-share/host.h: if compiling under Cygwin, make sure new
preprocessor define is defined. Define it if not.

autoconf yet.
* configure: regenerate.
* main.c: drop "32" from cygwin_ funcs, include sys/cygwin.h
where
cygwin path conv protos live, instead of adding a proto here
for
them here.

Looks like a big change, but it is really just a lot of small stuff.
In the cases where GCC was flagging a possible use-before-initialized
warning on variables, it turned out that these were being used properly
but GCC couldn't see that.
"wait.h" was defining all WIF* macro's instead of filling in those
that <wait.h> missed. Stops heaps of warnings from <wait.h>
re-defining WIF*s defined in "wait.h".

Cast parameters passed to make_cleanup to use the new
make_cleanup_func typedef.
More warning cleanups. There are still a bunch of places where the first
argument to make_cleanup is not cast to (make_cleanup_func); these are
either due to the function fitting the make_cleanup_func specification
already (e.g. free()) or they are in files that weren't compiled when
I did my make on a Linux native system. Bwahahaha. You can see them
like this:
grep make_cleanup\ * | grep -v make_cleanup_func
I'll surely go back and clean up the remaining suspicious calls in
GDB one of these days. :-)
* configure.in: Check for sys/debugreg.h, asm/debugreg.h.
* i386v-nat.c: Include asm/debugreg.h, sys/debugreg.h if it is not
present.
This is to work around a conflict where the Linux 2.1.x kernel and glibc
2.0.x are not in sync; including <sys/debugreg.h> will result in an error.
With luck, these losers will get their act together and we can trash
this hack in the near future.

* mdebugread.c (parse_partial_symbols): Fix handling of stabs
continuations, use xmalloc and xrealloc.
There should be sufficient information/hooks now to eliminate
this hack.

when the exec file has changed. Adding it here allows the
ui to be informed after symbol reading.
* gdbcore.h: Add declaration of file_changed_hook.
* stabsread.c (rs6000_builtin_type): Create a complex float instead
of an error.
(read_sun_floating_type): Similarly.
(read_range_type): Create a complex float if self_subrange is
true.

(remote_stop): New function which handles interrupting the
remote target so that CLUI and GUI use the same core functions
to achieve the same goal.
(remote_wait): Change to handle remote_stop properly.
[interrupted_already]: New static global to help remote_stop.
[remote_ops, extended_remote_ops]: Add remote_stop for to_stop member.
* target.c: Rename static function "ignore" to "target_ignore" and
export it so that gdb can determin if some target vector member is
actually not defined. Replace all occurances of ignore.
* target.h: Export target_ignore.
