* win32nat.c (handle_exceptions): Handle various arithmetic exceptions.
|
||||
* configure.in: Add an additional library to cygwin link.
|
||||
* configure: Regenerate.
|
||||
|
||||
Patch from Egor Duda <deo@logos-m.ru>:
|
||||
* coffread.c (coff_symfile_read): Reinstate ability to recognize "pe"
|
||||
type.
|
||||
|
||||
2000-01-07 Michael Snyder <msnyder@cleaver.cygnus.com>
|
||||
|
||||
* uw-thread.c: New file to support UnixWare user-mode threads:
|
||||
contributed by Nickolas Duffek <nsd@cygnus.com>.
|
||||
* target.h (struct target_ops): New vector, to_extra_thread_info,
|
||||
allows back-ends to give extra details in info thread display.
|
||||
(target_extra_thread_info): define new macro.
|
||||
(target_find_new_threads): simplify macro. Cleanup comments.
|
||||
* target.c (to_extra_thread_info): default and inherit new vector.
|
||||
(cleanup_target): eliminate PARAMS, break up long lines,
|
||||
provide default definition for to_extra_thread_info, and
|
||||
to_find_new_threads. Default to_thread_alive and to_query
|
||||
to return_zero, not target_ignore (they each return int not void).
|
||||
(debug_to_find_new_threads): new debug entry.
|
||||
(setup_target_debug): add debug_to_find_new_threads.
|
||||
* gdbthread.h: export struct thread_info, find_thread_pid, and
|
||||
iterate_over_threads. Add comments. Eliminate PARAMS. Update
|
||||
copyright. Add new private data pointer for use by target back-ends.
|
||||
* thread.c (struct thread_info): move definition to gdbthread.h.
|
||||
(find_thread_pid): new exported function for thread lookup.
|
||||
(iterate_over_threads): new exported function for applying
|
||||
arbitrary operations to threads. Update copyright to 2000.
|
||||
(info_threads_command): use new target_extra_thread_info vector
|
||||
to display extra information about each thread (if implemented).
|
||||
* config/i386/tm-i386v42mp.h: remove obsolete #defines for procfs.
|
||||
Add defines for PIDGET, etc.
|
||||
* config/i386/tm-i386sol2.h: ditto.
|
||||
* config/sparc/tm-sun4sol2.h: ditto.
|
||||
* config/i386/i386v42mp.mh: add uw-thread.o to NATDEPFILES.
|
||||
* testsuite/gdb.threads/pthreads.exp: Try to link with -lthread
|
||||
if -lpthread and -lpthreads fail.
|
||||
|
||||
* procfs.c: (PIDGET, TIDGET, MERGEPID): change default to no-op.
|
||||
(proc_flags): combine flags that UnixWare splits into two locations.
|
||||
(proc_modify_flag): add support for PR_KLC (kill on last close).
|
||||
(proc_[un]set_kill_on_last_close): new functions.

|
||||
2000-01-06 Fernando Nasser <fnasser@totem.to.cygnus.com>
|
||||
|
||||
* remote.c (remote_open_1): Fix message so it does not imply a
|
||||
specific syntax for serial ports, as it is OS dependent.
|
||||
(remote_async_open_1): Ibid.
|
||||
(init_remote_ops): Ibid.
|
||||
|
||||
2000-01-06 Fernando Nasser <fnasser@totem.to.cygnus.com>
|
||||
|
||||
* rdi-share/serdrv.c (SerialOpen): Use speed from "-b" argument or
|
||||
"set remotebaud" command (if set) when no speed is specified on
|
||||
the "target rdi" command.
|
||||
|
||||
2000-01-06 Fernando Nasser <fnasser@totem.to.cygnus.com>
|
||||
|
||||
* rdi-share/serdrv.c (find_baud_rate): Add entries for 57600 and
|
||||
115200.
|
||||
(baud_options[]): Ibid.
|
||||
|
||||
2000-01-06 Fernando Nasser <fnasser@totem.to.cygnus.com>
|
||||
|
||||
* rdi-share/unixcomm.c: Fix SERIAL_PREFIX so it matches the prefix
|
||||
used by each operating system.
|
||||
|
||||
2000-01-06 Elena Zannoni <ezannoni@kwikemart.cygnus.com>
|
||||
|
||||
* breakpoint.c (until_break_command): Add an argument for the
|
||||
continuation, the beginning of the cleanups set up by this
|
||||
command.
|
||||
(until_break_command_continuation): Do cleanups until the one
|
||||
passed in as argument instead of doing all of them.
|
||||
|
||||
* infcmd.c (finish_command_continuation): Expect a new argument,
|
||||
which indicates up to where to do cleanups. Update calls to
|
||||
do_exec_cleanups to use this marker, instead of ALL_CLEANUPS.
|
||||
(finish_command): Add another argument for the continuation: the
|
||||
starting cleanup for this command.
