2001-07-28Move libgdb library functions to gdb.h (new file).Andrew Cagney1-0/+1
Update everything related to this.
2001-06-132001-06-13 Michael Snyder <msnyder@redhat.com>Michael Snyder1-33/+42
* gdbthread.h (struct thread_info): Add new fields: current_line, current_symtab, step_sp, for saved infrun state. * thread.c (save_infrun_state, load_infrun_state): Save and restore current_line, current_symtab, and step_sp. (add_thread): Rather than adding assignments to initialize the new fields, just use memset (tp, 0, sizeof (*tp). This way future new fields will not be overlooked. * infrun.c (handle_inferior_event): Save and restore save_sp, current_line, and current_symtab when switching threads.
2001-06-022001-06-01 Michael Snyder <msnyder@redhat.com>Michael Snyder1-0/+17
* thread.c (delete_step_resume_breakpoint): New function. Maintain internal consistency of the thread list while deleting a step_resume_breakpoint. * gdbthread.h (delete_step_resume_breakpoint): Export. * breakpoint.c (bpstat_find_step_resume_breakpoint): Make thread-aware: don't return a step_resume_breakpoint for the wrong thread. * infrun.c (wait_for_inferior): Call delete_step_resume_breakpoint instead of delete_breakpoint_current_contents. (fetch_inferior_event): Ditto. (handle_inferior_event): Call delete_step_resume_breakpoint instead of delete_breakpoint.
2001-05-12* thread.c (do_captured_list_thread_ids): Use ui_out_tuple_beginJim Blandy1-2/+2
and ui_out_tuple_end instead of ui_out_list_begin and ui_out_list_end.

1999-01-13 * thread.c: cull duplicate prototypes. Move prototypes to top.Michael Snyder1-55/+32
* serial.c: indentation cleanup. * breakpoint.c: add casts to eliminate compiler warnings.
1999-01-06 * remote.c (record_curthread): Must not modify inferior_pid whenMichael Snyder1-2/+2
called from wait_for_inferior. Instead, if a new thread-id is detected, call add_thread. (MAGIC_NULL_PID): new macro, use instead of the magic number "42000". (remote_find_new_threads): if inferior_pid is unknown, get and use the current thread id. (remote_start_remote): on connecting, attempt to get the current thread id for inferior_pid. (remote_resume): If pid == -1, then resume any-thread (not the current thread specifically). * thread.c (info_threads_command): don't initialize current_pid until after call to FIND_NEW_THREADS (which may change inferior_pid).
1999-01-05Cosmetic and indentation fixes.Michael Snyder1-23/+26
1998-12-31all remaining *.c *.h files from hp merge.David Taylor1-12/+116
1998-11-13 * remote.c (remote_get_threadinfo) : Support for remoteJohn Metzler1-6/+88
multithread debugging. (remote_get_threadlist) : get a partial list of threads (remote_threadlist_iterator) : Step through all the threads (init_remote_threadtests) : Optional builtin unit test commands. * thread.c (bind_target_thread_vector) : Implementa a more dynamic way of accessing target specific thread info functions than FIND_NEW_THREADS. (target_thread_info) : Function to get extended thread information. * gdbthread.h : Export internal data structures corresponding to external detailed thread info response. This is more like a 'ps' command than what might be expected of host based threads. This is for embedded systems.
1998-10-141998-10-14 Jason Molenda (jsm@bugshack.cygnus.com)Jason Molenda1-18/+15
* defs.h: Move _initialize_printcmd, _initialize_stack, _initialize_blockframe out of here and in to their respective .c files. * blockframe.c: Move _initialize_blockframe prototype to here. * printcmd.c: Move _initialize_printcmd prototype to here. * stack.c: Move _initialize_stack prototype to here. * source.c, symtab.h: Move _initialize_source prototype to the .c file. * values.c, value.h: Move _initialize_values prototype to the .c file. * gdbthread.h, thread.c: Move _initialize_thread prototype to the .c file. * breakpoint.c, breakpoint.h: Move _initialize_breakpoint prototype to the .c file. * abug-rom.c alpha-nat.c alpha-tdep.c annotate.c ax-gdb.c bcache.c: Standardize comments for the prototype section of these files. * configure.in: Look in libc for wctype before looking for it in libc. The last one is to fix the GNU ld (~2.9.1) + Solaris 2.6 interaction problem where an empty stub library (libw) causes a core dump when we call vasprintf (e.g. `info br') in the final linked gdb.
1998-10-141998-10-13 Jason Molenda (jsm@bugshack.cygnus.com)Jason Molenda1-2/+4
* blockframe.c (find_pc_sect_partial_function): Add braces to avoid possible nested-if confusion. * breakpoint.c (breakpoint_here_p): Ditto. (breakpoint_inserted_here_p): Ditto. (breakpoint_thread_match): Ditto. * gnu-regex.c: Define _REGEX_RE_COMP only if it isn't already defined. * gnu-regex.h: Define _REGEX_RE_COMP to pick up old compatability prototypes. * symtab.h: Add prototype for _initialize_source. * value.h: Add prototype for _initialize_value. * defs.h: Include sys/types.h or stddef.h to get size_t. (make_cleanup): Add make_cleanup_func typedef and switch to using a prototype for this function. (mfree): Add prototypes for mmalloc, mrealloc, mfree if we aren't using mmalloc. * ax-gdb.c breakpoint.c coffread.c corelow.c dbxread.c dwarf2read.c dwarfread.c elfread.c eval.c exec.c gdbtk-cmds.c gdbtk.c infcmd.c infrun.c mipsread.c nlmread.c os9kread.c parse.c printcmd.c symfile.c symmisc.c symtab.c thread.c top.c tracepoint.c typeprint.c valops.c: Cast parameters passed to make_cleanup to use the new make_cleanup_func typedef. More warning cleanups. There are still a bunch of places where the first argument to make_cleanup is not cast to (make_cleanup_func); these are either due to the function fitting the make_cleanup_func specification already (e.g. free()) or they are in files that weren't compiled when I did my make on a Linux native system. Bwahahaha. You can see them like this: grep make_cleanup\ * | grep -v make_cleanup_func I'll surely go back and clean up the remaining suspicious calls in GDB one of these days. :-)
1998-10-061998-10-06 Jason Molenda (jsm@bugshack.cygnus.com)Jason Molenda1-1/+4

1997-10-24fix for PR 13618 -- gdb incorrectly reports thread information.David Taylor1-0/+4
If other systems besides nm-sun4sol2 exhibit the problem, they may need definitions of FIND_NEW_THREADS and a corresponding support function.

Thu Jul 25 19:41:31 1996 Fred Fish <fnf@cygnus.com> for a rather huge set of changes. I was going to put them here, but it made cvs dump core. :-(
1996-05-09 * Makefile.in, breakpoint.c, corelow.c, fork-child.c, inflow.c,Stu Grossman1-1/+1
infrun.c, mac-nat.c, procfs.c, remote.c, sol-thread.c, thread.c, win32-nat.c, config/nm-lynx.h: Rename thread.h to gdbthread.h to avoid conflict with Solaris /usr/include/thread.h.

1994-10-08 The point of these changes is to avoid reading the frame pointerJim Kingdon1-2/+0
and stack pointer during stepping, to speed things up. A. Changes to not select a frame until we need a selected frame: * blockframe.c (flush_cached_frames): Call select_frame (NULL, -1). * infrun.c (wait_for_inferior): Move call to select_frame back to normal_stop. This reverts a change of 13 Apr 94 (it says Jeff Law, but the change was my idea); the only reason for that change was so we could save and restore the selected frame in wait_for_inferior, and now that flush_cached frames clears the selected frame, that should work OK now. B. Changes to not create a current_frame until we need one: * blockframe.c (get_current_frame): If current_frame is NULL, try to create an innermost frame. * sparc-tdep.c (sparc_pop_frame), infcmd.c (run-stack_dummy), infrun.c (wait_for_inferior), thread.c (thread_switch), convex-tdep.c (set_thread_command), a29k-tdep.c (pop_frame), alpha-tdep.c (alpha_pop_frame), convex-xdep.c (core_file_command), h8300-tdep.c (h8300_pop_frame), h8500-tdep.c (h8300_pop_frame), hppa-tdep.c (hppa_pop_frame), i386-tdep.c (i386_pop_frame), i960-tdep.c (pop_frame), m68k-tdep.c (m68k_pop_frame), mips-tdep.c (mips_pop_frame), rs6000-tdep.c (push_dummy_frame, pop_dummy_frame, pop_frame), sh-tdep.c (pop_frame), config/arm/tm-arm.h (POP_FRAME), config/convex/tm-convex.h (POP_FRAME), config/gould/tm-pn.h (POP_FRAME), config/ns32k/tm-merlin.h (POP_FRAME), config/ns32k/tm-umax.h (POP_FRAME), config/tahoe/tm-tahoe.h (POP_FRAME), config/vax/tm-vax.h (POP_FRAME): Don't call create_new_frame. * corelow.c (core_open), altos-xdep.c (core_file_command), arm-xdep.c (core_file_command), gould-xdep.c (core_file_command), m3-nat.c (select_thread), sun386-nat.c (core_file_command), umax-xdep.c (core_file_command): Don't call create_new_frame; do call flush_cached_frames. * blockframe.c (reinit_frame_cache): Don't call create_new_frame or select_frame. C. Changes to get rid of stop_frame_address and instead only fetch the frame pointer when we need it. * breakpoint.c (bpstat_stop_status): Remove argument frame_address; use FRAME_FP (get_current_frame ()). * infrun.c (wait_for_inferior): Don't pass frame pointer to bpstat_stop_status. * infrun.c (wait_for_inferior): Use FRAME_FP (get_current_frame ()) instead of stop_frame_address. * infrun.c (save_inferior_status, restore_inferior_status), inferior.h (struct inferior_status): Don't save and restore stop_frame_address. * inferior.h, infcmd.c, thread.c (thread_switch), m3-nat.c (select_thread): Remove stop_frame_address and uses thereof. D. Same thing for the stack pointer. * infrun.c (wait_for_inferior): Remove stop_sp and replace uses thereof with read_sp (). E. Change to eliminate one nasty little spot where we were wanting to know the frame pointer from before the current step (idea from GDB 3.5, which saved my ass, because my other ideas of how to fix it were very baroque). * infrun.c: Remove prev_frame_address. * infrun.c (wait_for_inferior, step_over_function): Use step_frame_address instead of prev_frame_address. F. Same basic idea for the stack pointer. * inferior.h, infcmd.c: New variable step_sp. * infcmd.c (step_1, until_next_command): Set it. * infrun.c: Remove prev_sp and replace uses by step_sp. * infrun.c (wait_for_inferior): If we get out of the step range, then set step_sp to the current stack pointer before we start going again.
1993-11-10 gcc -Wall lint:Jim Kingdon1-1/+2
* thread.c: Include "gdbcmd.h" and <ctype.h>. * Makefile.in: Update dependency. * thread.c (thread_command): Remove unused variable p. * values.c (unpack_double): Use len instead of TYPE_LENGTH (type). * valprint.c (print_floating): Correctly check sign bit now that we are using unsigned arithmetic. * symtab.c (find_pc_line_range): Remove unused variables exact_match, ind, and l.
