Jeff Law 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

	(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.

Jim Kingdon f93b941bde * environ.c (set_in_environ): Eliminate special handling of PATH and
GNUTARGET.
	* putenv.c: Removed, conflicts with system declaration of
	putenv on RS/6000 running AIX 3.2.5, and above change makes it
	unnecessary.
	* Makefile.in: Change accordingly.
	* procfs.c (procfs_create_inferior): Change comment accordingly.

Jim Kingdon 08f74b9271 * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
* procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
	m3-nat.c (m3_create_inferior): Pass it.
	* procfs.c: Remove ptrace function.  It was declared in a way which
	conflicted with the prototype in unistd.h on Solaris.
1994-01-22 17:36:41 +00:00
Jim Kingdon 45dc9be388 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
* Move target_signal_from_host, target_signal_to_host, and
	store_waitstatus from inftarg.c to target.c.  procfs needs them.
	* target.c: Include "wait.h" and <signal.h>.
	* target.h, infrun.c (proceed), proceed callers: Pass new code
	TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
	enums being treated as unsigned and is cleaner.
	* infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
	TARGET_SIGNAL_0.
	* infcmd.c (signal_command), infrun.c (signals_info):
	Don't allow user to specify numeric equivalent of

Jim Kingdon 67ac975911 * target.h: Add enum target_waitkind, enum target_signal, and

	be struct target_waitstatus * instead of int *.
	* target.h, infrun.c, all targets: Change type of signal arguments
	to resume(), proceed(), and target_resume() from int to enum
	target_signal.
	* All targets (*_wait, *_resume): Change accordingly.
	* infcmd.c (program_info, signal_command), throughout infrun.c,
	* fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
	* convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
	signal code stuff right with the new signals would be non-trivial).
	* inferior.h (stop_signal): Make it enum target_signal not int.
	* target.c, target.h (target_signal_to_string, target_signal_to_name,
	target_signal_from_name): New functions.
	* inftarg.c, target.h (target_signal_to_host, target_signal_from_host,

	print_fault.
	* config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.

Thomas Lord 199b2450f6 Change the stream argument to _filtered to GDB_FILE *.
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.

1993-10-27 19:30:27 +00:00
Jim Kingdon 976bb0be03 * Makefile.in (init.c): Generate using the source, not munch. This
cleans up all kinds of hassles (which nm to use in munch, etc).  The
	new formatting conventions (mostly already followed) are that
	the name of the _initialize_* routines must start in column zero,
	and must not be inside #if.
	* munch: Removed.
	* Makefile.in: Remove references to munch.
	* serial.c, remote.c, infptrace.c, maint.c, convex-tdep.c,
	alpha-tdep.c, hp300ux-nat.c, hppab-nat.c, osfsolib.c, remote-es.c,

	z8k-tdep.c: Make sure the above conventions are followed.  Make
	sure they are all declared as returning void.  Clean up
	miscellaneous comments and such.
1993-10-22 05:55:58 +00:00

(detach):  Clear faults and set RLC flag to make process run
when we close it.
(open_proc_file):  New `mode' argument for O_RDONLY or O_RDWR.

libiberty/strsignal.c.  Widespread changes to use libiberty/strerror.c
functions for errno manipulations and libiberty/strsignal.c for signo
(signals) manipulations.
1992-04-22 16:46:47 +00:00

1992-04-03 19:29:29 +00:00
Fred Fish 5c1c5e6745 Fix bug in values.c unpacking signed characters on hosts where the default
character type is unsigned.  Add some cases to the tables in procfs.c
for constants defined in newer SVR4 systems and reorder the tests for
ioctl support of resetting the inherit-on-fork flag to favor the latest
method using PIOCRESET.
1992-04-02 18:00:10 +00:00
Fred Fish cc221e76d6 Many changes to procfs.c, mostly to expand the "info proc" command and to
fix a couple of small bugs.  Changes to other files mostly to fix minor
things pointed out by the SGI compiler.  See ChangeLog for complete details.
1992-04-01 19:46:14 +00:00
Fred Fish 6b80138803 Changes in procfs.c to fix bug with inferior's siginfo struct getting
needlessly stomped.  Changes in elfread.c and solib.c to fix DWARF
processing, broken by other recent changes.
1992-04-01 03:09:02 +00:00
Stu Grossman fad3fc945a * procfs.c (open_proc_file): Disable inherit-on-fork flag so that
commands in .cshrc/.profile won't get traced.

* All GDB files that #include defs.h: Removed stdio.h.
	(defs.h): #include stdio.h.

This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion.  (n.b.
many configurations don't build for other reasons.)

command that prints /proc specific information, changes to solib.c to
allow more flexible handling of finding the dynamic linker structures,
changes to utils.c and defs.h to add a new null_cleanup() function to
serve as an anchor point for cleanup chains with no obvious "first
cleanup".
1991-12-28 06:27:24 +00:00
Fred Fish f8b76e70b7 Numerous small changes and a complete reorganization of solib.c, to support
