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

PR 15992.
With a bp_step_resume type breakpoint, the frame pointer check exists in
case we recurse and execute the same text section--we want to not stop
there because it would confuse the user. So gdb checks to see that the
frame pointer matches the one recorded in the breakpoint.
If the current frame pointer is less than the frame pointer recorded in
the breakpoint, then something odd is happened and we should declare that
we're at the breakpoint so that we clear it out.
This happens in Purify instrumented executables on PA systems, at least.
They insert some calls out to Purify code in the function epilogue and
it confuses GDB (which assumes that the frame pointer does not move
around through the entire execution of a function).

breakpoint and resuming after a breakpoint in 16 bit mode is
completely disfunctional. * monitor.h : Defined additional hooks
for dmpregs, confinuer_hooks and wait_filter. These additions
require that all rom monitor interfaces be recoded to to

* irix5-nat.c, osfsolib.c (xfer_link_map_member, solib_map_sections,
symbol_add_stub): Ditto.
* gdb/gdb_string.h (strdup): Declare only if not defined as a
macro.
Mark glibc development versions are defining strdup as a macro and the
prototype hosees it. Either way, this patch shouldn't cause problems.
* procfs.c: Added replacement macros for LWP stuff. Fixed support
for UnixWare / SVR4.2MP targets and any targets which use
multi-file /proc entries. Fixed support for hardware watchpoints.

Mon Apr 20 14:12:30 1998 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* infrun.c (wait_for_inferior): Don't add signalled processes
as new threads.
* procfs.c (wait_fd): Note if LWP has exited.
(procfs_wait): use GETPID to get process ID.
NOTE: I didn't commit Kean's changes to configure.host/configure.tgt
yet because they are kind of bogus and I'm punting back to him to let
him figure out what he's trying to do. So configuring for UnixWare
may not work just yet.
(sparc_extract_return_value): New function, required to handle
machines without floating point.
(sparc_store_return_value): Ditto.
* config/sparc/tm-sparc.h (EXTRACT_RETURN_VALUE): Call
sparc_extract_return_value instead of using inline code.
(sparc_extract_return_value): Declare.
(STORE_RETURN_VALUE): Call sparc_store_return_value instead
of using inline code.
(sparc_store_return_value): Declare.
work correctly on little-endian hosts.
(sparc_push_arguments): New function.
(gdb_print_insn_sparc): New function.
(_initialize_sparc_tdep): Make gdb_print_insn_sparc the default
disassembler, so that SPARClite-specific instructions will
be recognized.
* sparcl-tdep.c (readchar): Print debugging information.
(debug_serial_write): New function, a replacement for SERIAL_WRITE
that prints debugging information.
* config/sparc/tm-sparc.h (PUSH_ARGUMENTS): Define.
(sparc_push_arguments): Declare.
* configure.tgt: Switch over to use tm-4320.h. Since I switched to
MIPS EABI the fixes are no longer backward compatible with 4300.
* tm-vr4320.h: Added
* vr4320.mt: Added
* utils.c: (warning) added call to warning_hook
* source.c: (find_source_lines) modified to call warning in case
of source vs. executable time stamp mismatch. Simplified object
file check. Initialized mtime to 0.
* defs.h: added warning_hook prototype
* top.c: added warning_hook prototype.
* gdbtk.c: (perror_with_name_wrapper) new function to call
perror_with_name safely.

added include <sys/stat.h>
Update support for x86 Solaris 2.
* config/i386/tm-i386sol2.h, nm-i386sol2.h: New configuration
files for x86 Solaris 2.
* config/i386/i386sol2.mt, i386sol2.mh: Use them.
* config/sparc/tm-sun4sol2.h (PROCFS_GET_CARRY): New macro, extract
carry flag from a given regset.
(IS_STATIC_TRANSFORM_NAME): New macro, check if a symbol name
is a SunPro transformed name.
* i386-tdep.c (sunpro_static_transform_name): New function to
extract the source name from a SunPro transformed name.
* inferior.h (procfs_first_available, procfs_get_pid_fd):
Add prototypes.
* infrun.c (wait_for_inferior): Handle breakpoint hit in
signal handler without intervening stop in sigtramp.
* procfs.c (procfs_lwp_creation_handler): Use PROCFS_GET_CARRY
instead of direct access to the status register.
(procfs_get_pid_fd): New function, returns procfs fd for a given pid.
* sol-thread.c (ps_lgetLDT): New function, returns LDT for a given
lwpid.
(sol_find_new_threads): Handle failed libthread_db initialization
gracefully.
* stabsread.c (define_symbol): Use IS_STATIC_TRANSFORM_NAME
to check for a SunPro transformed symbol name.
* mips-tdep.c (unpack_mips16): Fixed instruction decoding, lots of
bit pattern interpretations. mips_fetch_instruction does not work
for 16 bit instructions. Some confusion remains about sign
extension in backward branches.
(mips32_relative_offset): Sign extension
(mips32_next_pc): Major debugging, bit pattern interpretation
(print_unpack): debugging printf
(fetch_mips_16): new funtion, key on PC low bit, not symbol table
(mips16_next_16): Initial major debugging of this function. Lots
of bit pattern mistakes.
(mips_next_pc): key on low bit of PC, not symbol table.
* symfile.c(generic_load) : Added a download verification which
reads back the loade code. Download chunk size is now a defined
macro. Fixed a bug in which downloading slips into loading one
byte at a time. Lower level functions in monitor.c can load long
sequences of bytes and make use of these fixups. Referencing
bfd-start_address directly was incorrectly getting zero for start.
section in an ELF file, override a symbol's ECOFF section with its
ELF section. Also, fix stabs continuation where a stabs string
continues for more than one continuation.
* ns32k-tdep.c (flip_bytes, ns32k_localcount,
ns32k_get_enter_addr, sign_extend): Restore functions mysteriously
deleted.
* ns32knbsd-nat.c: New (?) file to support fetching and storing
registers on NetBSD hosts.
* nbsd.mh (NATDEPFILES): put ns32knbsd-nat.o instead of
ns32k-nat.o
* ns32km3-nat.c (reg_offset): Get order of floating point
registers correct. Add extra 32382 register offsets.
(REG_ADDRESS): define to point at correct part of thread
state. Use calls to "warning" instead of "message".
* tm-nbsd.h, tm-ns32km3.h (REGISTER_NAMES, NUM_REGS,
REGISTER_BYTES, REGISTER_BYTE): redefine allowing for 32382
fpu registers.
* rdi-share/Makefile.am, rdi-share/aclocal.m4,
rdi-share/configure: New files.
* rdi-share/configure.in: Rewritten to be an autoconf input file.
* rdi-share/Makefile.in, rdi-share/configure: Generated by
automake/autoconf.
* rdi-share/dbg_hif.h, etherdrv.c, hostchan.c: Use autoconf tests
to check environment.
automake/autoconfiscate rdi-share. We don't use the checks that autoconf
provides too much for now, but it'll be easier to use them if any problems
crop up in the future. (rdi-share/ is foreign code and it probably isn't
worth spending any more time than necessary messing with it.)
* gdbtk.c: (gdb_trace_status) new function.
(gdbtk_init) added command "gdb_is_tracing".
(tracepoint_notify) added passcount information.
* tracepoint.c (trace_status_command): Recognize a boolean return
value from the stub to indicate whether trace experiment is
running. Export this value as a global state variable
(trace_running_p) for use by the GUI. (from Michael Snyder)
(trace_pass_command) added call to modify_tracepoint_hook.
* tracepoint.h export trace_running_p
* breakpoint.c (breakpoint_re_set_one): Treat bp_shlib_events
like bp_breakpoints.
* solib.c (solib_create_inferior_hook): Relocate section addresses
if the alleged start address doesn't agree with the PC.
* gdbserver/Makefile.in: add dependency on XM_CLIBS.
* gdbserver/low-sim.c (registers) force into alignment.
(create_inferior): Fix typo on new_argv; add abfd arg to
sim_open, sim_create_inferior. Add reg_size arg to
sim_fetch_register, sim_store_register. Make simulator
take a single-step to get into a known running state.
* gdbserver/gdbreplay.c: include fcntl.h for def'n of F_SETFL.
* gdbserver/server.c: Add remote_debug variable to control
debug output.
* gdbserver/server.h: Add prototypes for enable/disable_async_io.
* gdbserver/remote-utils.c: add verbose debugging output controlled
by "remote_debug" variable. Add call to "disable_async_io()"
to avoid being killed by async SIGIO signals.
* config/m32r/m32r.mt: define GDBSERVER_(LIBS and DEPFILES),
so that gdbserver can be built with the m32r simulator.
unsigned types.
Specify size of r5900 FSR using 32 bit unsigned type.
Correctly format mips registers when some are not 64 bits in size
Check that REGISTER_{RAW,VIRTUAL}_SIZE are consistent when the target
specifies that no conversion is needed when moving from one to the
other.
* minsyms.c (compare_minimal_symbols): If addresses are identical,
then compare on names. Sorted list should have symbols with
identical addresses AND names adjacent, so dups can be discarded.
* config/m68k/xm-sun3os4.h: Remove malloc declarations, they
are handled via autoconf now.
* remote.c (remote_ops, extended_remote_ops): Replace static
forward declaration by moving the static definition to the top of
the file, for old K&R compilers.
* tracepoint.c (collect_symbol, trace_start_command):
Replace ANSI string concatenation with K&R compatible simple string.
* utils.c (quit): Call SERIAL_DRAIN_OUTPUT rather than
SERIAL_FLUSH_OUTPUT.
* serial.h (struct serial_ops): Add drain_output, pointer to
function that waits for output to drain.
(SERIAL_DRAIN_OUTPUT): Macro to wait for output to drain.
* ser-unix.c (hardwire_drain_output): New function and prototype.
* ser-unix.c (hardwire_ops): Add entry for drain_output function.
* ser-tcp.c (tcp_ops): Ditto.
* ser-ocd.c (ocd_ops): Ditto.
* ser-mac.c (mac_ops): Ditto.
* ser-go32.c (dos_ops): Ditto.
* ser-e7kpc.c (e7000pc_ops): Ditto.
* serial.c (_initialize_serial): Add a description of
"set remotelogbase".
* command.c (do_setshow_command): If no arguments are supplied,
don't dump core, instead print out an error message.
* alpha-nat.c (fetch_osf_core_registers): Renamed from
fetch_aout_core_registers.
(alpha_osf_core_fns): Renamed from alpha_aout_core_fns, change
flavour to bfd_target_unknown_flavour for OSF core files.
