2011-04-14	cheap trick to further optimize locking normal mutexes	Rich Felker	-1/+1

2011-03-30	cheap special-case optimization for normal mutexes	Rich Felker	-0/+4
	cycle-level benchmark on atom cpu showed typical pthread_mutex_lock call dropping from ~120 cycles to ~90 cycles with this change. benefit may vary with compiler options and version, but this optimization is very cheap to make and should always help some.
2011-03-17	implement robust mutexes	Rich Felker	-3/+3
	some of this code should be cleaned up, e.g. using macros for some of the bit flags, masks, etc. nonetheless, the code is believed to be working and correct at this point.
2011-03-17	unify lock and owner fields of mutex structure	Rich Felker	-2/+3
	this change is necessary to free up one slot in the mutex structure so that we can use doubly-linked lists in the implementation of robust mutexes.
2011-03-16	correct error returns for error-checking mutexes	Rich Felker	-1/+5

2011-02-17	reorganize pthread data structures and move the definitions to alltypes.h	Rich Felker	-1/+1
	this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test.
2011-02-12	initial check-in, version 0.5.0v0.5.0	Rich Felker	-0/+9
