2011-04-17	debloat: use __syscall instead of syscall where possible	Rich Felker	-1/+1
	don't waste time (and significant code size due to function call overhead!) setting errno when the result of a syscall does not matter or when it can't fail.
2011-04-14	cheap trick to further optimize locking normal mutexes	Rich Felker	-1/+1

2011-03-29	revert mutex "optimization" that turned out to be worse	Rich Felker	-1/+1

2011-03-20	global cleanup to use the new syscall interface	Rich Felker	-2/+2

2011-03-17	implement robust mutexes	Rich Felker	-3/+35
	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	-3/+2
	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.
2011-03-17	optimize contended normal mutex case; add int compare-and-swap atomic	Rich Felker	-1/+1

2011-03-16	simplify logic, slightly optimize contended case for non-default mutex types	Rich Felker	-4/+2

2011-03-16	correct error returns for error-checking mutexes	Rich Felker	-1/+1

2011-03-08	simplify and optimize pthread_mutex_trylock	Rich Felker	-17/+16

2011-03-08	fix and optimize non-default-type mutex behavior	Rich Felker	-15/+12
	problem 1: mutex type from the attribute was being ignored by pthread_mutex_init, so recursive/errorchecking mutexes were never being used at all. problem 2: ownership of recursive mutexes was not being enforced at unlock time.
2011-02-17	reorganize pthread data structures and move the definitions to alltypes.h	Rich Felker	-13/+13
	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/+28
