bp_watchpoint_scope breakpoints.
(struct breakpoint): Add val_chain and related_breakpoint fields
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.

or hardware watchpoint.

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.
(clear_command, breakpoint_re_set_one, enable_command): 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.

* hppab-nat.c (hppa_set_watchpoint): New function.
* config/pa/nm-hppab.h (STOPPED_BY_WATCHPOINT): Define.
(HAVE_STEPPABLE_WATCHPOINT): Define.
(TARGET_CAN_USE_HARDWARE_WATCHPOINT): Define.
(target_{insert,delete}_watchpoint): Define.
PSYMTAB_TO_SYMTAB, call target_terminal_ours_for_output first.
This is needed now that wait_for_inferior passes in endaddr.
* infrun.c: Move call to target_terminal_inferior from proceed
to resume.
beyond the end of the last function in an objfile.
* coff-solib.c (coff_solib_add): Use BFD to get fields from .lib
section.
* infrun.c (wait_for_inferior): Modify test for subroutine entry
to include pc out of bounds of the previous function.
* remote.c (remote_wait): Use strtoul for parsing 'N' message.
Add code to relocate symfile_objfile->sections.
* 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.
instead of doing it ourself.
* blockframe.c (reinit_frame_cache): Use code which was in
generic_mourn_inferior so we can use this function even when
we have switched targets.
* corelow.c (core_detach): Call reinit_frame_cache.
* target.c (target_detach): Don't call generic_mourn_inferior
(revert yesterday's change, now handled by core_detach).
* objfiles.c (free_objfile): Detach any core file if we call
SOLIB_CLEAR. #include target.h.
the saved pc from sigcontext on the stack for BSD signal handling.
* config/i386/tm-i386bsd.h (SIGTRAMP_START, SIGTRAMP_END, FRAME_CHAIN,
FRAMELESS_FUNCTION_INVOCATION, FRAME_SAVED_PC, SIGCONTEXT_PC_OFFSET):
Define to make backtracing through sigtramp work.
* config/vax/tm-vax.h (SIGTRAMP_START, SIGTRAMP_END, TARGET_UPAGES,
FRAME_SAVED_PC, SIGCONTEXT_PC_OFFSET): Ditto.
config/gould/tmp-{pn,np1}.h,
config/{sparc/tm-sparc.h,pyr/tm-pyr.h,vax/tm-vax.h}: Remove field
next_frame from struct frame_info. It has no purpose beyond
->next->frame and is an artifact from GDB 2.8.
calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
* tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
Define two variants, one faster.
* sparc-tdep.c (sparc_frame_chain): Use target_read_memory
and return zero, rather than giving an error.
(setup_arbitrary_frame): Initialize the PC in the new frame.
(skip_prologue): Add a second arg saying whether we're just
checking for a frameless function or not.
