Make writing to files work properly. (Fixes to BFD are also needed.)
* core.c (core_open): Open file ourselves, read or r/w, depending on
write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.

mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h: Add support for
stepping (and nexting) through longjmp(). Also, cleanup
breakpoint handling quite a bit by creating explicit breakpoint
types instead of using magic breakpoint numbers.

Make writing to files work properly. (Fixes to BFD are also needed.)

write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.

are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.

Changes to support alpha OSF/1 in native mode.
* alpha-nat.c, alpha-tdep.c, config/alpha/alpha-osf1.mt,
config/alpha/nm-alpha.h, config/alpha/tm-alpha.h, osfsolib.c:
New files.
* Makefile.in: Add new files and dependencies.
* configure.in: Add alpha target.
* config/alpha/alpha-osf1.mh (NATDEPFILES): Add osfsolib.o
* config/alpha/alpha-osf1.mh (MH_CFLAGS): Remove, we can handle
shared libraries now.
* config/alpha/xm-alpha.h: Cleanup, get MAKEVA_* defines right.
* defs.h (CORE_ADDR): Make its type overridable via CORE_ADDR_TYPE,
provide `unsigned int' default.
* breakpoint.c (breakpoint_auto_delete): Delete only if we really
stopped for the breakpoint.
* stabsread.c, stabsread.h (define_symbol): Change valu parameter
to a CORE_ADDR.
* stabsread.c (read_range_type): Handle the case where the lower
bound overflows and the upper doesn't and the range is legal.
* infrun.c (resume): Do not step a breakpoint instruction if
CANNOT_STEP_BREAKPOINT is defined.
* inferior.h (CALL_DUMMY_LOCATION): New variant AT_ENTRY_POINT.
Now that we have the bp_call_dummy breakpoint the call dummy code
is no longer needed. PUSH_DUMMY_FRAME, PUSH_ARGUMENTS and
FIX_CALL_DUMMY can be used to set up everything for the dummy.
The breakpoint for the dummy is set at the entry point and thats it.
* blockframe.c (inside_entry_file, inside_entry_func): Do not stop
backtraces if pc is in the call dummy at the entry point.
* infcmd.c (run_stack_dummy): Handle AT_ENTRY_POINT case. Use
the expected breakpoint pc when setting up the frame for
set_momentary_breakpoint.
* symfile.c (entry_point_address): New function for AT_ENTRY_POINT
support.
* valops.c (call_function_by_hand): Handle AT_ENTRY_POINT case.

* breakpoint.h (enum bptype): Add bp_hardware_watchpoint and
bp_watchpoint_scope breakpoints.

for use by watchpoints.
* breakpoint.c (within_scope): Delete. No longer used.
(TARGET_CAN_USE_HARDWARE_WATCHPOINT): Provide default definition.
(target_{remove,insert}_watchpoint): Likewise.
(can_use_hardware_watchpoint): New function.
(remove_breakpoint): New function to remove a single breakpoint
or hardware watchpoint.
(insert_breakpoints): Handle insertion of hardware watchpoints.
Store a copy of the value chain derived from the watchpoint
expression.
(remove_breakpoints): Simplify by using remove_breakpoint.
(delete_breakpoint): Likewise.
(watchpoint_check): Delete the watchpoint and watchpoint scope
breakpoints when the watchpoint goes out of scope. Save & restore
the current frame after checking watchpoints.
(breakpoint_init_inferior): Likewise (restarting the program
makes all local watchpoints go out of scope).
(bpstat_stop_status): Handle hardware watchpoints much like normal
watchpoints. Delete the watchpoint and watchpoint scope breakpoint
when the watchpoint goes out of scope. Remove and reinsert all
breakpoints before returning if we stopped when a hardware watchpoint
fired.
(watch_command): Use a hardware watchpoint when possible. If
watching a local expression, build a scope breakpoint too.
(map_breakpoint_numbers): Also call given function for any
related breakpoints.
(disable_breakpoint): Never disable a scope breakpoint.
(enable_breakpoint): Handle hardware breakpoints much like normal
breakpoints, but recompute the watchpoint_scope breakpoint's
frame and address (if we have an associated scope breakpoint).
(read_memory_nobpt): Handle hardware watchpoints like normal
watchpoints. When necessary handle watchpoint_scope breakpoints.
(print_it_normal, bpstat_what, breakpoint_1, mention): Likewise.

(disable_command): Likewise.
* blockframe.c (find_frame_addr_in_frame_chain): New function.
Extern prototype added to frame.h
* infrun.c (wait_for_inferior): Set current_frame and select
a frame before checking if we stopped due to a hardare watchpoint
firing. Handle stepping over hardware watchpoints.
(normal_stop): Remove unnecessary call to select_frame.
* value.h (value_release_to_mark): Declare.
* values.c (value_release_to_mark): New function.
* procfs.c (procfs_wait): Add cases for hardware watchpoints.
(procfs_set_watchpoint, procfs_stopped_by_watchpoint): New functions.
* hppab-nat.c (hppa_set_watchpoint): New function.

Make writing to files work properly. (Fixes to BFD are also needed.)
* core.c (core_open): Open file ourselves, read or r/w, depending on
write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.

(build_function_symbol): Remove #if 0'd code.
* rs6000-tdep.c: Cleanup. Add static fn protos.
Use CORE_ADDR for addresses throughout. Make void fns void.
(pop_dummy_frame): Add FIXME about bogosity of design here.
(rs6000_struct_return_address): Ditto.
(frameless_function_invocation, frame_get_cache_fsr,
frame_initial_stack_address, xcoff_relocate_symtab,
xcoff_init_loadinfo, free_loadinfo, xcoff_add_toc_to_loadinfo,

static exec_one_dummy_insn. Move a mess of functions to
rs6000-tdep.c (as above). Remove #if 0'd code.
* config/rs6000.mh (XDEPFILES): Move xcoffexec.o to target side.
(XM_CLIBS): Add -lm to circumvent AIX 3.2 libc ldexp bug.
* config/rs6000.mt (TDEPFILES): Adopt xcoffexec.o.

Fix many sins which will come up in 32 bit x 64 bit GDB, and
various miscellaneous things discovered in the process:
* printcmd.c, defs.h (print_address_numeric): New function.
* c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
Use it.
* utils.c, defs.h (gdb_print_address): New function.
* expprint (dump_expression), gdbtypes.h: Use it.
* breakpoint.c (describe_other_breakpoints),
symmisc.c (dump_symtab, print_symbol):
Use filtered not unfiltered I/O.
(remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
just run gdb under a debugger for this (and it had problems with
printing addresses, how to print b->shadow, etc.).
* buildsym.c (make_blockvector), core.c (memory_error),
exec.c (print_section_info), maint.c (print_section_table),
mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
Add comments saying code is broken. Marked with "FIXME-32x64".
* dbxread.c (process_one_symbol), partial-stab.h (default),
remote-vx.c (vx_run_files_info):
Don't cast int being passed to local_hex_string.
* symmisc.c (print_symbol): Don't cast long being passed to %lx.
* symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
only being a long.
* symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
and LOC_LOCAL.
* printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
* source.c: Include <sys/types.h> regardless of USG.

Make writing to files work properly. (Fixes to BFD are also needed.)
* core.c (core_open): Open file ourselves, read or r/w, depending on
write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.

Changes to support alpha OSF/1 in native mode.
* alpha-nat.c, alpha-tdep.c, config/alpha/alpha-osf1.mt,
config/alpha/nm-alpha.h, config/alpha/tm-alpha.h, osfsolib.c:
New files.
* Makefile.in: Add new files and dependencies.
* configure.in: Add alpha target.
* config/alpha/alpha-osf1.mh (NATDEPFILES): Add osfsolib.o
* config/alpha/alpha-osf1.mh (MH_CFLAGS): Remove, we can handle
shared libraries now.
* config/alpha/xm-alpha.h: Cleanup, get MAKEVA_* defines right.
* defs.h (CORE_ADDR): Make its type overridable via CORE_ADDR_TYPE,
provide `unsigned int' default.
* breakpoint.c (breakpoint_auto_delete): Delete only if we really
stopped for the breakpoint.
* stabsread.c, stabsread.h (define_symbol): Change valu parameter
to a CORE_ADDR.
* stabsread.c (read_range_type): Handle the case where the lower
bound overflows and the upper doesn't and the range is legal.
* infrun.c (resume): Do not step a breakpoint instruction if
CANNOT_STEP_BREAKPOINT is defined.
* inferior.h (CALL_DUMMY_LOCATION): New variant AT_ENTRY_POINT.
Now that we have the bp_call_dummy breakpoint the call dummy code
is no longer needed. PUSH_DUMMY_FRAME, PUSH_ARGUMENTS and
FIX_CALL_DUMMY can be used to set up everything for the dummy.
The breakpoint for the dummy is set at the entry point and thats it.
* blockframe.c (inside_entry_file, inside_entry_func): Do not stop
backtraces if pc is in the call dummy at the entry point.
* infcmd.c (run_stack_dummy): Handle AT_ENTRY_POINT case. Use
the expected breakpoint pc when setting up the frame for
set_momentary_breakpoint.
* symfile.c (entry_point_address): New function for AT_ENTRY_POINT
support.
* valops.c (call_function_by_hand): Handle AT_ENTRY_POINT case.

breakpoint handling quite a bit by creating explicit breakpoint
types instead of using magic breakpoint numbers.
Makefile.in: Update version to 4.4.3

Make writing to files work properly. (Fixes to BFD are also needed.)
* core.c (core_open): Open file ourselves, read or r/w, depending on
write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.

Make writing to files work properly. (Fixes to BFD are also needed.)
* core.c (core_open): Open file ourselves, read or r/w, depending on
write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.

Make writing to files work properly. (Fixes to BFD are also needed.)
* core.c (core_open): Open file ourselves, read or r/w, depending on
write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.

Make writing to files work properly. (Fixes to BFD are also needed.)
* core.c (core_open): Open file ourselves, read or r/w, depending on
write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.

/* OK, when we call objfile_relocate, we need to relocate breakpoints

too. breakpoint_re_set is not a good choice--for example, if

addr_string contains just a line number without a file name the
|
|
|
|
|
breakpoint might get set in a different file. In general, there is

|
|
|
no need to go all the way back to the user's string (though this might

work if some effort were made to canonicalize it), since symtabs and

Probably the best way to solve this is to have each breakpoint save
|
|
|
|
|
the objfile and the section number that was used to set it (if set
|
|
|
|
|
by "*addr", probably it is best to use find_pc_line to get a symtab
|
|
|
|
|
and use the objfile and block_line_section for that symtab). Then
|
|
|
|
|
objfile_relocate can call fixup_breakpoints with the objfile and
|
|
|
|
|
the new_offsets, and it can relocate only the appropriate breakpoints. */
