* Pass correct parameter size.davidxu2006-09-051-2/+2

* Remove unused file.davidxu2006-08-291-59/+0

* pthread_sigmask is in thr_sig.c, remove this file.davidxu2006-08-281-52/+0

* Kill unused files.davidxu2006-08-282-187/+0

* Use umutex APIs to implement pthread_mutex, member pp_mutexq is addeddavidxu2006-08-284-73/+116
| | | | | | into pthread structure to keep track of locked PTHREAD_PRIO_PROTECT mutex, no real mutex code is changed, the mutex locking and unlocking code should has same performance as before.
* Add umutex APIs.davidxu2006-08-282-0/+92

* 1. Don't override underscore version of aio_suspend(), system(),davidxu2006-07-253-78/+169
| | | | | | | | | | wait(), waitpid() and usleep(), they are internal versions and should not be cancellation points. 2. Make wait3() as a cancellation point. 3. Move raise() and pause() into file thr_sig.c. 4. Add functions _sigsuspend, _sigwait, _sigtimedwait and _sigwaitinfo, remove SIGCANCEL bit in wait-set for those functions, the signal is used internally to implement thread cancellation.

* - Use same priority range returned by kernel's sched_get_priority_min()davidxu2006-04-276-55/+57
| | | | | and sched_get_priority_max() syscalls. - Remove unused fields from structure pthread_attr.

* Do not check validity of timeout if a mutex can be acquired immediately.davidxu2006-04-083-80/+103
| | | | | Completly drop recursive mutex in pthread_cond_wait and restore recursive after resumption. Reorganize code to make gcc to generate better code.

* Remove priority mutex code because it does not work correctly,davidxu2006-03-277-1199/+200
| | | | | | | | | to make it work, turnstile like mechanism to support priority propagating and other realtime scheduling options in kernel should be available to userland mutex, for the moment, I just want to make libthr be simple and efficient thread library. Discussed with: deischen, julian

* Add some more pthread stubs so that librt can use them.deischen2006-03-051-4/+35
| | | | | | | The thread jump table has been resorted, so you need to keep libc, libpthread, and libthr in sync. Submitted by: xu

* Increase the number of spinlocks, since libc's malloc implementation isjasone2006-01-131-1/+1

* In preparation for a new malloc implementation:jasone2006-01-121-10/+4
| | | | | | | | | | | | | * Add posix_memalign(). * Move calloc() from calloc.c to malloc.c. Add a calloc() implementation in rtld-elf in order to make the loader happy (even though calloc() isn't used in rtld-elf). * Add _malloc_prefork() and _malloc_postfork(), and use them instead of directly manipulating __malloc_lock.
