David Xu	d6e0eb0a48	Replace function _umtx_op with _umtx_op_err, the later function directly ... returns errno, because errno can be mucked by user's signal handler and most of pthread api heavily depends on errno to be correct, this change should improve stability of the thread library.	2008-04-02 07:41:25 +00:00

David Xu	d99f6dac14	- Remove variable _thr_scope_system, all threads are system scope. ... - Rename _thr_smp_cpus to boolean variable _thr_is_smp. - Define CPU_SPINWAIT macro for each arch, only X86 supports it.	2006-12-15 11:52:01 +00:00
David Xu	b7e118b1e0	Remove declaration of _thr_initial from MD header file, it is no longer ... needed.	2006-04-04 03:35:26 +00:00
David Xu	7bd761788d	Simplify _get_curthread() and _tcb_ctor because libc and rtld now ... already allocate thread pointer space in tls block for initial thread. Only i386 and amd64 have been done, others still have to be tested.	2006-04-04 03:26:06 +00:00
David Xu	a091d823ad	Import my recent 1:1 threading working. some features improved includes: ... 1. fast simple type mutex. 2. __thread tls works. 3. asynchronous cancellation works ( using signal ). 4. thread synchronization is fully based on umtx, mainly, condition variable and other synchronization objects were rewritten by using umtx directly. those objects can be shared between processes via shared memory, it has to change ABI which does not happen yet. 5. default stack size is increased to 1M on 32 bits platform, 2M for 64 bits platform. As the result, some mysql super-smack benchmarks show performance is improved massivly. Okayed by: jeff, mtm, rwatson, scottl	2005-04-02 01:20:00 +00:00
