* i386/cygmon.ld: Add entry for .gcc_except_table.
2000-10-25 Mark Salter <msalter@redhat.com>
* i386/cygmon-crt0.S: Use __USER_LABEL_PREFIX__ for symbols. Always
use __start for start symbol.
* i386/cygmon-salib.c: Don't build __do_global_[cd]tors for AOUT.
Disable file I/O extensions to make Plum Hall happy.
* i386/cygmon.ld: Set __start as entry point.
* i386/Makefile.in: Support IS_AOUT.
* i386/configure.in: Support IS_AOUT.
* i386/configure: Regenerated.
* i386/cygmon-salib.c:
* i386/cygmon-gmon.c (_mcount): It's _etext.
(cygthread::initialized): Delete.
(cygthread::stub): Use exiting variable to determine when to exit.
(cygthread::runner): Delete.
(cygthread_protect): New variable.
(cygthread::init): Don't start runner thread. Initialize muto for list
protection.
(cygthread::freerange): Return pointer to cygthread.
(cygthread::operator new): Change logic to start threads on an as-needed basis.
(cygthread::detach): Don't zero id.
(cygthread::terminate): Don't kill any executing threads. Just set exiting
flag.
* cygthread.h (cygthread): Reflect above changes.
* dcrt0.cc (dll_crt0_1): Move cygthread initialization later.
* fork.cc (fork_child): Do fdtab fixup after dll fixup or (apparently) winsock
may allocate memory in dll load address.
cygheap->user, return the uid or gid from myself.
* security.cc (alloc_sd): If gid == myself->gid, return the group sid from
cygheap->user. Remove the test for uid == original_uid, which is
counter-productive.
(init_cheap): Ditto for declaration.
* fork.cc (fork_parent): Use user_heap element in cygheap.
* heap.h (inheap): Ditto.
* heap.cc (sbrk): Ditto.
(heap_init): Ditto. Reorganize to shrink heap chunk as required and record new
value in cygheap.
* dcrt0.cc (dll_crt0_1): More "move the cygthread init" games.
* shared.cc (open_shared): Rework memory protection to properly deal with
relocated shared segment.
(shared_info::heap_chunk_size): Rename element to 'heap_chunk'.
* shared_info.h (shared_info): Ditto for declaration.
* strace.cc (strace::hello): Report on heap chunk size from cygheap since it
may shrink.
* cygwin.din: Remove last vestiges (?) of newlib wrappers.
* cygthread.cc (cygthread::detach): Always wait for event or suffer an
apparently inavoidable race.
* dcrt0.cc (dll_crt0_1): Allocate threads after stack has been relocated.
* debub.cc (lock_debug): Don't acquire lock on exit.
* fork.cc (fork_child): Recreate mmaps before doing anything else since Windows
has a habit of using blocks of memory in the child that could previously have
been occupied by shared memory in the parent.
* mmap.cc (fhandler_disk_file::fixup_mmap_after_fork): Issue error here and
provide some details about what went wrong.
(fixup_mmaps_after_fork): Remove error message.
* shared.cc (open_shared): Move warning message so that more detail is
possible.
* sigproc.cc (sigproc_init): Initialize sync_proc_subproc to avoid a race.
(sigproc_terminate): Specifically wait for process thread to terminate.
* crt1.c: Define new macro __IN_MINGW_RUNTIME before including
stdlib.h. Comment on reason.
Define WIN32_MEAN_AND_LEAN before including windows.h
* include/stdlib.h (_fmode): Protect declaration as dllimported
variable with __IN_MINGW_RUNTIME.
2002-10-19 Igor Pechtchanski <pechtcha@cs.nyu.edu>
* crt1.c: Include stdlib.h.
Rename _pid() to pid() throughout.
* Makefile.in: Compile some objects with -fomit-frame-pointer.
* cygwin.din: Reverse aliasing for _kill.
* syscalls.cc (_getpid_r): New function, implemented for newlib compatibility.
* shared.cc (open_shared): Remove reserving of memory since previous change
eliminate the need for this hack.
* fork.cc (fork_child): Initialize cygwin thread later in process to avoid
allocating memory for thread stacks.
* shared.cc (open_shared): Issue warning if NT and shared segment is relocated.
* shared.cc (shared_info::heap_chunk_size): Store info as megabytes. Search
HKEY_LOCAL_MACHINE as well as HKEY_CURRENT_USER.
* shared_info.h (shared_info::initial_heap_size): Change element name to
reflect new functionality.
* strace.cc (strace::hello): Report on initial heap size.
* testsuite/include/check.h: New header file to use with
test cases.
* testsuite/lib/newlib.exp: Add testsuite/include directory
to list of header files to use.
* testsuite/newlib.wctype/twctype.c: New test case for iswctype fns.
* testsuite/newlib.wctype/wctype.exp: New file.
* dtable.h (dtable::set_file_pointers_for_exec): Declare new function.
* spawn.cc (spawn_guts): Call dtable::set_file_pointers_for_exec to set
pointers to EOF when execing non-cygwin applications.
(child_info_fork::mount_table): Remove.
(child_info_fork::myself_addr): Remove.
* fork.cc (fork_child): Don't set either of the above.
* dcrt0.cc (dll_crt0_1): Call memory_init as early as possible.

(pinfo::init): Get myself address from open_shared.
* pinfo.h (myself_addr): Remove declaration.

protected. Take shared memory type as fifth argument.

* shared_info.h (shared_locations): New enum.
(console_state): Move here.
(open_shared): Reflect open_shared arg change in declaration.
