1994-04-14 * procfs.c (procfs_wait): Protect watchpoint code with appropriateJeff Law1-0/+6
#ifdefs.
1994-04-13 * breakpoint.h (enum bptype): Add bp_hardware_watchpoint andJeff Law1-0/+54
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.

(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.

* 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.
1994-01-06 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.Jim Kingdon1-40/+25
* 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 TARGET_SIGNAL_DEFAULT.
1994-01-04 * target.h: Add enum target_waitkind, enum target_signal, andJim Kingdon1-14/+13
struct target_waitstatus. Change status argument to target_wait to 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, store_waitstatus): New functions. * procfs.c (procfs_notice_signals): Use them. * i960-tdep.c (i960_fault_to_signal): New function, to replace print_fault. * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
1993-11-01Change the stream argument to _filtered to GDB_FILE *.Thomas Lord1-20/+20
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 * fork-child.c (fork_inferior): Set inferior_pid before callingJim Kingdon1-0/+3
init_trace_fun. Move the code which gets us through the shell to new function startup_inferior. * inferior.h: Declare startup_inferior. * procfs.c (procfs_init_inferior), inftarg.c (ptrace_him): Call startup_inferior. * m3-nat.c (m3_trace_him): Call intercept_exec_calls. * config/nm-m3.h: Don't define STARTUP_INFERIOR. * config/i386/tm-i386m3.h, config/ns32k/tm-ns32k.h, config/mips/tm-mipsm3.h: Don't define START_INFERIOR_TRAPS_EXPECTED.
1993-10-22 * Makefile.in (init.c): Generate using the source, not munch. ThisJim Kingdon1-17/+0
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, procfs.c, remote-udi.c, ser-go32.c, ultra3-xdep.c, sh-tdep.c, i960-tdep.c, hppa-tdep.c, h8500-tdep.c, dpx2-nat.c, delta68-nat.c, z8k-tdep.c: Make sure the above conventions are followed.

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.
1992-04-01Many changes to procfs.c, mostly to expand the "info proc" command and toFred Fish1-96/+1860
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.
1992-04-01Changes in procfs.c to fix bug with inferior's siginfo struct gettingFred Fish1-17/+75
needlessly stomped. Changes in elfread.c and solib.c to fix DWARF processing, broken by other recent changes.
1992-03-31* procfs.c (open_proc_file): Disable inherit-on-fork flag so thatStu Grossman1-0/+4
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.)
1992-02-22* Check in Fred Fish's changes in these modules. FredJohn Gilmore1-79/+107
will make ChangeLog entries for all of them.
1992-01-24Misc small fixes for problems uncovered by prototyping.Fred Fish1-6/+7
1991-12-28Many small changes to procfs.c to add base support for a new "info proc"Fred Fish1-41/+284
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".
1991-12-16Numerous small changes and a complete reorganization of solib.c, to supportFred Fish1-0/+87
SVR4 shared libraries in a manner very close to the original SunOS support. See the ChangeLog for details.
