1996-03-04 * From Peter Schauer:Jeff Law1-2/+16
* infrun.c (wait_for_inferior): Remove breakpoints and switch terminal settings before calling SOLIB_ADD. * solib.c (enable_break, SVR4 variant): Don't map in symbols for the dynamic linker, the namespace pollution causes real problems.
1996-01-23 * symfile.c (auto_solib_add): Renamed from auto_solib_add_at_startup.Jeff Law1-3/+83
All references changed. * breakpoint.c (bpstat_what): Add shlib_event to the class types. Update state table. Reformat so that it's still readable. When we hit the shlib_event breakpoint, set the calss of shlib_event. (breakpoint_1): Add "shlib events" as a breakpoint type. Print the shlib_event breakpoint like other breakpoints. (create_solib_event_breakpoint): New function. (breakpoint_re_set_one): Handle solib_event breakpoints. * breakpoint.h (enum bytype): Add bp_shlib_event breakpoint type. (enum bpstat_what_main_action): Add BPSTAT_WHAT_CHECK_SHLIBS action. (create_solib_event_breakpoint): Declare. * infrun.c (wait_for_inferior): Handle CHECK_SHLIBS bpstat. (normal_stop): Inform the user when the inferior stoped due to a shared library event. (_initialize_infrun): Add new set/show variable "stop_on-solib-events" to control whether or not gdb continues the inferior or stops it when a shared library event occurs. * minsyms.c (lookup_minimal_symbol_solib_trampoline): New function. * somsolib.c (TODO list): Update. (som_solib_create_inferior_hook): Arrange for gdb to be notified when significant shared library events occur. * hppa-tdep.c (find_unwind_entry): No longer static. First cut at the machine independent changes for 7363. Also includes code to automatically track shl_load/shl_unload calls on hpux.
1995-10-24 * infrun.c (wait_for_inferior): Disable questionable code nearStu Grossman1-6/+20
the step range test. Replace call detection test with much simpler (and more efficient) test that doesn't require prologue examination (as often). * symtab.c symtab.h (in_prologue): New function that indicates whether or not we are in a function prologue. This uses the symbol table, and then falls back to prologue examination if that fails. It's much more efficient for remote debugging because it avoids examining memory, which is very slow. This is used in wait_for_inferior to determine if we've made a function call that needs to be skipped over (for next/nexti). * mips-tdep.c (after_prologue): New function, returns the PC after the prologue. Uses PDRs and the symbol table. (mips_find_saved_regs): Use in_prologue() to avoid costly prologue examination if possible. (mips_skip_prologue): Use after_prologue() if possible to avoid costly prologue examination.

Correctly choose between the single and multi-threaded step and continue ptrace calls. Some of the lynx-6100 single stepping fixes.
1995-05-15 * infrun.c: Add #ifdef HP_OS_BUG to all references toStu Grossman1-75/+48
trap_expected_after_continue. * (wait_for_inferior): Fix for remote watchpoints. Don't try to insert breakpoints while target is running (this only works on *some* native targets). This may also speed up native watchpoints considerably.

(bpstat_what_main_action): New code BPSTAT_WHAT_THROUGH_SIGTRAMP. * breakpoint.c (bpstat_what): Return BPSTAT_WHAT_THROUGH_SIGTRAMP if we hit a bp_through_sigtramp breakpoint. Remove kludge which ignored bs->stop for a bp_step_resume breakpoint. * infrun.c (wait_for_inferior): Make a through_sigtramp_breakpoint which performs one (the check_sigtramp2 one) of the functions which had been handled by the step_resume_breakpoint. For each use of the step_resume_breakpoint, make it still use the step_resume_breakpoint, use the through_sigtramp_breakpoint, or operate on both. Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what. When setting the frame address of the step resume breakpoint, set it to the address for frame *before* the call instruction is executed, not after.

1993-12-30 * infrun.c (wait_for_inferior): Enable code which assumes that ifJim Kingdon1-10/+15
we jump into the prologue from another function, then it was a subroutine call. #if 0 AT_FUNCTION_START; the above code should take care of this case.
1993-12-26Sun Dec 26 16:59:39 1993 Jim Kingdon (kingdon@lioth.cygnus.com)Jim Kingdon1-23/+47
* infrun.c (wait_for_inferior): Remove confusing and inaccurate stuff about subroutine calls, return, etc., from comment which says "We've wandered out of the step range.". Sun Dec 26 09:18:10 1993 Peter Schauer (pes@regent.e-technik.tu-muenchen.de) * infrun.c (wait_for_inferior): When checking whether the line has changed, check the symtab as well.
1993-11-01Change the stream argument to _filtered to GDB_FILE *.Thomas Lord1-18/+11
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.
1993-10-25 * infrun.c (wait_for_inferior): Fix PC out of subroutine boundsStu Grossman1-6/+8
check to use prev_func_start/end instead of stop_func_start/end. * remote-udi.c (store_register): Invalidate NPC/PC_REGNUM after changing PC.

1993-10-17 * infrun.c (wait_for_inferior): Clean up comments which were atJim Kingdon1-92/+41
the top of the file, making them more concise and moving them with the code (Sorry, Randy, but these stream-of-consciousness comments really have to go). Switch the order of the "&&", which makes things clearer and turns out to be an improvement with respect to side effects and speed.

Also, define FLAGS_REGNUM for access to the `flags' pseudo-reg. * (REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Use memcpy, not bcopy. * (CANNOT_STORE_REGISTER): New from Utah.
