999dd04b89 * breakpoint.h (enum bptype): Add bp_hardware_watchpoint and
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.
	(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.
	(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.
	(procfs_set_watchpoint, procfs_stopped_by_watchpoint): New functions.

	* 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.

82a2edfbcf * breakpoint.c, breakpoint.h, c-valprint.c, ch-valprint.c,
cp-valprint.c, eval.c, expprint.c, findvar.c, language.c,
	objfiles.h, infcmd.c, printcmd.c, stack.c, typeprint.c,
	valarith.c, valops.c, valprint.c, value.h, values.c: Replace
	value with value_ptr.  This is for the ptx compiler.
	* objfiles.h, target.h: Don't declare a "sec_ptr" field using a
	"sec_ptr" typedef.
	* symm-nat.c: Add a bunch of stuff for symmetry's ptrace stuff.
	#if 0 i386_float_info.
	* symm-tdep.c (round): Remove.  Also remove sgttyb.
	* symm-tdep.c: Remove lots of stuff which duplicates stuff from
	i386-tdep.c.  Remove register_addr and ptx_coff_regno_to_gdb.
	* i386-tdep.c (i386_frame_find_saved_regs): Put in
	I386_REGNO_TO_SYMMETRY check in case it is needed for Dynix
	someday.
	* config/i386/nm-symmetry.h: Change KERNEL_U_ADDR.  Move
	stuff from PTRACE_READ_REGS, PTRACE_WRITE_REGS macros to
	symm-nat.c.  Define CHILD_WAIT and declare child_wait().
	* config/i386/tm-symmetry.h: Remove call function stuff; stuff in
	tm-i386v.h is apparently OK.
	* config/i386/xm-symmetry.h [_SEQUENT_]: Define HAVE_TERMIOS not
	HAVE_TERMIO.  Define MEM_FNS_DECLARED, NEED_POSIX_SETPGID, and
	USE_O_NOCTTY.

30974778c1 * value.h (struct value): Add modifiable field.
* values.c (allocate_value, record_latest_value, value_copy): Set it.
	(record_latest_value): Don't mess with VALUE_LVAL of value.
	* valops.c (value_assign): Check it.  Reword existing error
	message on not_lval.

* symmisc.c (print_symbol): Use %02x not %2x for LOC_CONST_BYTES.

	Clean up problems with targets and hosts that have 64 bit longs
	and pointers and 32 bit ints.
	* breakpoint.c, buildsym.c, c-lang.c, c-valprint.c, ch-lang.c,
	ch-valprint.c, core.c, cp-valprint.c, dbxread.c, exec.c,
	expprint.c, gdbtypes.c, infcmd.c, language.c, language.h,
	m2-lang.c, maint.c, mips-tdep.c, mipsread.c, partial-stab.h,
	printcmd.c, remote-vx.c, solib.c, source.c, stack.c, symfile.c,
	symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
	Change all printf formats from %x to %lx if outputting an address.
	Change la_*_format to use long format.
	local_hex_string, local_hex_string_custom now take an unsigned long
	argument, change all callers.
	* coffread.c (read_coff_symtab):  Remove superfluous cast for
	complaint output.
	* dbxread.c (end_psymtab):  Cast MSYMBOL_INFO to long, not int.
	* findvar.c, value.h (write_register):  Change register value to long.
	* gdbtypes.h (struct type):  Change `bitsize' to long as
	TYPE_FIELD_STATIC_PHYSNAME uses this field as a pointer.
	* inferior.h (struct inferior_status):  Change type of stop_pc to
	CORE_ADDR.
	* language.h (local_octal_string, local_octal_string_custom):
	Remove prototype, the functions are neither defined nor used.
	* mipsread.c (parse_symbol):  Use temporary variable for bitsize as
	f->bitsize is a long now.
	* objfiles.c (add_to_objfile_sections, build_objfile_section_table):
	Use unsigned long casts instead of int for abusing sections_end
	pointer as integer.
	* stack.c (parse_frame_specification):  Change type of `args' to
	CORE_ADDR for SETUP_ARBITRARY_FRAME.

	* printcmd.c (make_vasize):  Allow redefinition via MAKEVA_SIZE.
	* mipsread.c (parse_type):  Alpha cc now supports the t->continued
	bit, update algorithm to match the way the compiler uses it.

7efb57c33d * defs.h (CC_HAS_LONG_LONG): Set up to define CC_HAS_LONG_LONG
when compiling with gcc, but disable it for now.  See comment.
	* defs.h (LONGEST):  Define as either "long" or "long long"
	based on CC_HAS_LONG_LONG.
	* defs.h (longest_to_int):  Use CC_HAS_LONG_LONG to control
	how longest_to_int is defined.
	* c-valprint.c (c_val_print):  Call print_longest.
	* expprint.c (dump_expression):  Use PRINTF_HAS_LONG_LONG
	instead of LONG_LONG.
	* {printcmd.c, gdbtypes.h} (LONG_LONG):  Replace usages with
	CC_HAS_LONG_LONG.
	* printcmd.c (print_scalar_formatted):  Call print_longest
	and let it figure out what to do for PRINTF_HAS_LONG_LONG.
	* typeprint.c (print_type_scalar):  Call print_longest and let
	it figure out what to do for PRINTF_HAS_LONG_LONG.
	* valprint.c (val_print_type_code_int):  Call print_longest
	and let it figure out what to do for PRINTF_HAS_LONG_LONG.
	* stabsread.c (LONG_LONG):  Replace usages with CC_HAS_LONG_LONG.
	* value.h (struct value):  Replace usage of LONG_LONG with
	CC_HAS_LONG_LONG.
	* value.h (print_longest):  Add prototype.
	* values.c (LONG_LONG):  Replace usages with CC_HAS_LONG_LONG.
	* values.c (unpack_double):  Collapse code that was unnecessarily
	dependent on CC_HAS_LONG_LONG.  Use LONGEST instead of direct types.
	* values.c (value_from_longest):  Remove dependency on
	CC_HAS_LONG_LONG and just use LONGEST.
	* solib.c (solib_map_sections):  Use bfd_get_filename
	to access filename field.
	* solib.c (clear_solib):  Save filename and free it later, after
	bfd_close, since bfd_close may reference it.  Use bfd_get_filename
	to access the field.
	* config/convex/xm-convex.h (LONG_LONG):  Replace with
	CC_HAS_LONG_LONG.  Add define for PRINTF_HAS_LONG_LONG.
	* doc/gdbint.texinfo (LONG_LONG):  Replace with CC_HAS_LONG_LONG.

e17960fb42 * core.c, eval.c, exec.c, inftarg.c, remote-adapt.c, remote-eb.c,

target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
Remove to_call_function and target_call_function, since it
always calls the same thing (call_function_by_hand).
