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.

step_resume_breakpoint for IN_SIGTRAMP cases.
* infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
breakpoint.c (bpstat_what): Move step_resume from its own field of
the struct bpstat_what into the main_action. Make it override
other breakpoints. This is a conservative change in the sense
that before the step resume breakpoint was a breakpoint.c
breakpoint, hitting the step resume breakpoint overrode even
calling bpstat_stop_status.
|
|
* breakpoint.c, breakpoint.h (frame_in_dummy): New function.
* stack.c (print_frame_info): Use it.

Change all references to stdout/stderr to gdb_stdout/gdb_stderr.
Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')
Replaced calls to fopen for output to gdb_fopen.
Added sufficient goo to utils.c and defs.h to make the above work.
The net effect is that stdio output functions are only directly used
in utils.c. Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.
In the near future, GDB_FILE will stop being equivalant to FILE.
The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior. The testsuite doesn't notice anything
like this, though.
Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code. All output from commands
should go to a GDB_FILE.
Target-specific code can still use stdio directly to communicate with
targets.

that clears the `inserted' flag for all breakpoints and deletes
any breakpoints which should go away between runs of programs.
* inflow.c (generic_mourn_inferior), infrun.c (init_wait_for_inferior),
remote-es.c (es1800_load), comments in exec.c and corelow.c:
Use it instead of mark_breakpoints_out.
* breakpoint.c (mark_breakpoints_out): Update comment, tm-rs6000.h
uses it in a completely different context.
* breakpoint.c (breakpoint_re_set_one): Add bp_call_dummy case.

* 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.

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.

* remote-bug.c: remove redundant includes of value.h, target.h,
serial.h.
(bug_open): corrected typo, sr_multi_scan -> gr_multi_scan.
(bug_fetch_register): special case sfip register for m88110.
remove flag bit masking of pc registers. This should be handled
by the ADDR_BITS_* macros.
(bug_store_register): special case sfip register for m88110.
Corrected sprint format for extended registers.

trying to roll our own. Move check for a pc between SIGTRAMP_START and

step_resume_break_address with step_resume_breakpoint (now local
to wait_for_inferior).
({insert,remove}_step_breakpoint): Remove.
(wait_for_inferior): Set step resume break with
set_momentary_breakpoint. Test hitting it with bpstat_stop_status

a few more gotos.

machines with different sized basic types (ints, ptrs, etc).
(Idea from pierre@la.tce.com (Pierre Willard).)
* value.c (value_from_longest): Rename from value_from_long.
Handle pointer types as well as integers, so that targets with
different pointer sizes from the host can be accomodated.
* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
valarith.c, valops.c, valprint.c, value.h, values.c: Rename
uses of value_from_long to value_from_longest.
* eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass

raw search.
* breakpoint.c, remote-vx.c: Reword strings printed by
catch_errors callers.
|
|

(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

since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
