1999-05-29 Roland McGrath <roland@baalperazim.frob.com>
* cthreads.h (mutex_clear): Change again, to call mutex_init.
* cthreads.h (mutex_clear): Change from syntax error to no-op (with
warning avoidance).
1998-11-12 Mark Kettenis <kettenis@phys.uva.nl>
* cthreads.c (cthread_init): Move cthread_alloc call before
cproc_init call, since cthread_alloc uses malloc, and malloc won't
work between initializing the new stack and switching over to it.
1998-07-20 Roland McGrath <roland@baalperazim.frob.com>
* i386/csw.S (cproc_prepare): Take address of cthread_body as third
arg, so we don't have to deal with PIC magic to find its address
without producing a text reloc.
* cprocs.c (cproc_create): Pass &cthread_body to cproc_prepare.
Tue Jun 9 13:50:09 1998 Thomas Bushnell, n/BSG <tb@mit.edu>
* cthreads.c (cthread_fork_prepare): Don't call
malloc_fork_prepare since we are no longer providing our own
malloc in this library.
(cthread_fork_parent): Likewise, for malloc_fork_parent.
(cthread_fork_child): Likewise, for malloc_fork_child.
Wed Aug 20 15:39:44 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* cthreads.c (cthread_body): Wire self before calling user work
function. This way all cthreads will be wired, which the ports
library (and hurd_thread_cancel, etc.) depend on.
Fri Aug 8 13:21:17 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* Makefile (SRCS): Delete malloc.c; libc now has a thread safe
malloc.
(malloc.c): Delete file.
Mon Jun 9 21:18:46 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* cthreads.c (cthread_fork): Delete debugging oddity that crept
into source.
Thu Apr 3 20:29:27 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* i386/csw.S: Define __ELF__ too.
Wed Feb 19 23:29:55 1997 Miles Bader <miles@gnu.ai.mit.edu>
* stack.c (__hurd_threadvar_stack_mask,
__hurd_threadvar_stack_offset, __hurd_threadvar_max): Make extern.
Tue Feb 18 16:28:36 1997 Miles Bader <miles@gnu.ai.mit.edu>
* i386/thread.c (cproc_setup): Correctly leave space at top of
stack for GNU per-thread variables.
Mon Nov 18 16:36:56 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* cprocs.c (cproc_create): Cast CHILD in assignment.
Mon Oct 21 22:05:48 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* i386/csw.S (CALL_MCOUNT): New macro.
(cproc_swtich, cproc_start_wait, cproc_prepare): Use CALL_MCOUNT.
* rwlock.h: Change extern inline protection to use new canonical
method.
* rwlock.c: Rewritten.
Wed Sep 4 09:06:09 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* Makefile (VPATH): Look in $(asm_syntax) instead of old
$(machine); Hurd configure now folds equivalent CPU types into
asm_syntax.
Thu Aug 29 12:50:37 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* i386/csw.S: Include <mach/i386/asm.h> instead of <i386/asm.h>.
Define ELF before inclusion.
Sat Jul 20 15:47:24 1996 Michael I. Bushnell, p/BSG <mib@gnu.ai.mit.edu>
* Makefile (lndist-i386-files): Look for I386SRCS and I386HDRS in
$(srcdir).
Thu Jun 6 07:29:31 1996 Miles Bader <miles@gnu.ai.mit.edu>
* malloc.c (more_memory): Use assert_perror instead of MACH_CALL.
"cthread_internals.h": Include removed.
Thu May 9 11:13:42 1996 Michael I. Bushnell, p/BSG <mib@gnu.ai.mit.edu>
* Makefile (installhdrs, installhdrsubdir): Install headers using
the generic technique, now that installhdrsubdir is available.
* rwlock.h: If _RWLOCK_DEFINE_FUNCTIONS is defined, then clear
_EXTERN_INLINE, but *after* header files have been included.
* rwlock.c (_RWLOCK_DEFINE_FUNCTIONS): New macro; use in place of
clearing _EXTERN_INLINE, which conflicts with machine-sp.h.
Sat May 4 05:33:57 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* cthreads.h [lint] (NEVER): Spurious global variable removed.
[!lint] (NEVER): Useless macro removed.

(LCLHDRS): Add rwlock.h.
(install): Depend on $(includedir)/rwlock.h.
($(includedir)/%.h: %.h): New rule.
($(includedir)/cthreads.h): Target removed, obviated by that rule.
* rwlock.h: Moved to libthreads from libshouldbeinlibc.
(_EXTERN_INLINE): New macro.
Use it for all the inline defns.
* rwlock.c: New file.
Thu Apr 11 17:55:24 1996 Michael I. Bushnell, p/BSG <mib@gnu.ai.mit.edu>
* Makefile (CFLAGS): Turn off -Wall.
* Makefile (VPATH): Fix up for new configure reality.
Thu Mar 7 15:52:38 1996 Miles Bader <miles@gnu.ai.mit.edu>
* malloc.c (realloc): Use LOG2_MIN_SIZE.
(LOG2_MIN_SIZE): New macro.
* malloc.c (realloc): Don't bother allocating a new block if the
new size request fits in the old one and doesn't waste any space.
Only free the old block if we successfully got a new one.
Wed Mar 6 18:05:57 1996 Miles Bader <miles@gnu.ai.mit.edu>
* malloc.c [MCHECK] (struct header): New type.
(union header): Only define if !MCHECK.
(HEADER_SIZE, HEADER_NEXT, HEADER_FREE, HEADER_CHECK): New macros.
[MCHECK] (MIN_SIZE): Add correct definition for this case.
(more_memory, malloc, free, realloc): Use above macros, and add
appropiate checks & frobs in MCHECK case.
Wed Jan 31 20:05:57 1996 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* cancel-cond.c: Add assert to check for signal bug.
Wed Jan 24 13:38:11 1996 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* cthreads.h: Use prototypes for functions of zero args.
Sun Dec 10 08:41:36 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* stack.c (addr_range_check, probe_stack): Functions #if 0'd out.
(stack_init): Don't call probe_stack or frob old stack at all.
Default cthread_stack_size to 16 pages if it is zero.
Wed Dec 6 14:48:37 1995 Michael I. Bushnell, p/BSG <mib@gnu.ai.mit.edu>

Use it in place of EXT.
* Makefile (csw_pic.o): Bogus braindead target from hell removed.
Bushnell will be shot.
Fri Sep 22 13:51:22 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* cprocs.c: Include hurd/threadvar.h.
Sat Sep 16 13:42:02 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* Makefile (CPPFLAGS): Variable removed.
(lndist-i386-files): Use $(top_srcdir) in place of $(srcdir).
Wed Sep 13 15:49:17 1995 Michael I. Bushnell, p/BSG <mib@duality.gnu.ai.mit.edu>

Thu Jul 6 13:39:25 1995 Michael I Bushnell <mib@duality.gnu.ai.mit.edu>
