1999-12-13 Michael Snyder <msnyder@cleaver.cygnus.com>
* breakpoint.h (enum bptype): add new BP type bp_thread_event.
This will be used when a target needs to set an invisible
breakpoint to detect events such as thread creation.
* breakpoint.c (interlan_breakpoint_number): remove ifdefs.
(create_thread_event_breakpoint): new function.
(remove_thread_event_breakpoints): new function.
(bpstat_what): don't stop at invisible thread_event breakpoints.
(update_breakpoints_after_exec): if bp_thread_event breakpoins
still exist after an exec, delete them. They'll need to be
found and installed anew anyway.
(print_it_typical): don't announce bp_thread_event breakpoints.
(print_one_breakpoint): account for new breakpoint type.
(mention): don't mention invisible bp_thread_event breakpoints.
(delete_command): don't delete invisible bp_thread_event bp's.
(breakpoint_re_set_one): don't touch bp_thread_event bp's.
Mon Dec 13 11:10:59 1999 Jimmy Guo <guo@cup.hp.com>
* language.h (longest_raw_hex_string, longest_local_hex_string,
longest_local_hex_string_custom): Declare.
* language.c: New functions, and misc. fixes.
(longest_raw_hex_string, longest_local_hex_string,
longest_local_hex_string_custom): New functions.
* c-typeprint.c
(c_type_print_varspec_prefix,c_type_print_varpsec_suffix): Add
TYPE_CODE_TEMPLATE case and default case.
(c_type_print_base): Revise how demangled_no_class is found;
print '}' before printing local file:line info.
* c-valprint.c (c_value_print): print reference type to class.
* valarith.c (value_binop): Add support for exponentiation,
equal, not equal.
(my_strcmp): New function.
(value_equal,value_less): Add string equality comparison support.
* m2-exp.y (lex): add default case statement to capture
unhandled token and call error().
1999-12-13 Elena Zannoni <ezannoni@kwikemart.cygnus.com>
* main.c (main): Remove unused variable.
From Hubert VERSTRAETE (hubertV@bigfoot.com):
* main.c (captured_main): Disambiguate command line option '-d' by
preferring --directory over --dbx.
* top.c (return_to_top_level): Do not do exec cleanups if the
target is executing. Those cleanups are supposed to be done when
the target has stopped.
Mon Dec 13 20:52:37 1999 Andrew Cagney <cagney@b1.cygnus.com>
* breakpoint.c (do_captured_breakpoint_query,
gdb_breakpoint_query): New functions. Implement a breakpoint
query.

ep_type_description.
Mon Dec 13 12:38:31 1999 Andrew Cagney <cagney@b1.cygnus.com>
* top.h: Delete #include <setjmp.h>. Moved to top.c.
(SIGJMP_BUF, SIGSETJMP, SIGLONGJMP, SIGJMP_BUF, SIGSETJMP,
SIGLONGJMP): Delete. Moved to top.c
(error_return, quit_return): Delete extern declarations.
* top.c: #include <setjmp.h>.
(error_return, quit_return): Make static.
(SIGJMP_BUF, SIGSETJMP, SIGLONGJMP, SIGJMP_BUF, SIGSETJMP,
SIGLONGJMP): Define.
Mon Dec 13 11:54:12 1999 Andrew Cagney <cagney@b1.cygnus.com>
* tracepoint.c (trace_start_command, tracepoints_info): Print
step_count using %ld.
* Makefile.in (tracepoint.o): Compile tracepoint.o with -Werror.
1999-12-12 Elena Zannoni <ezannoni@kwikemart.cygnus.com>
* target.h (enum target_waitkind): Add new enumeration value
TARGET_WAITKIND_IGNORE. For inferior events that we should do
nothing about.
* remote.c (remote_async_wait): After each character of console
output from the inferior, return to the event loop with an event
kind of TARGET_WAITKIND_IGNORE instead of looping here.
* infrun.c (handle_inferior_event): In case of
TARGET_WAITKIND_IGNORE, return immediately, and set things up so
that we are still waiting for the inferior.
1999-12-12 Elena Zannoni <ezannoni@kwikemart.cygnus.com>
* event-loop.c (handle_timer_event): When calling the timer
procedure, use the saved_timer data, not the timer_ptr data,
because the latter has been already freed.
Fri Dec 10 12:01:43 1999 Andrew Cagney <cagney@b1.cygnus.com>
* eval.c (evaluate_subexp): Only inline when GNUC and not STDC.
Sat Dec 11 17:52:03 1999 Andrew Cagney <cagney@b1.cygnus.com>
* breakpoint.c (print_one_breakpoint): New function. Move
breakpoint print code to here.
(breakpoint_1): From here.
Mon Dec 6 20:31:28 1999 Andrew Cagney <cagney@b1.cygnus.com>
* gdbarch.sh: Replace field init_p with invalid_p.
(TARGET_BFD_VMA_BIT): New architecture vector method. Defaults to
architecture bits_per_address.

file_frame_chain_valid. Rename alternate_frame_chain_valid to
func_frame_chain_valid.
* config/sparc/tm-sparclite.h, config/mips/tm-mipsv4.h,
config/m88k/tm-delta88v4.h, config/m68k/tm-m68kv4.h,

* blockframe.c (alternate_frame_chain_valid,
default_frame_chain_valid): Swap implementations. The change Mon
Nov 30 11:18:48 1998 Andrew Cagney <cagney@chook> which converted
several macros to functions was backwards.
* mips-tdep.c (mips_gdbarch_init): Update. Call
alternate_frame_chain_valid and not default_frame_chain_valid.
Wed Dec 8 15:29:48 1999 Andrew Cagney <cagney@b1.cygnus.com>
* infptrace.c: Simplify handling of <sys/wait.h>. Always include
"wait.h" from the ../include/wait.h directory. #include
<sys/wait.h> was added as part of Mon Nov 29 12:14:10 1999 Andrew
Cagney <cagney@b1.cygnus.com> but the ChangeLog was omitted.
1999-12-07 Jim Blandy <jimb@cygnus.com>
