2014-07-19	fix missing barrier instructions in powerpc atomic asm	Rich Felker	-1/+4

2014-07-19	fix build breakage from ppc asm constraints change	Rich Felker	-3/+3
	due to a mistake in my testing procedure, the changes in the previous commit were not correctly tested and wrongly assumed to be valid. the lwarx and stwcx. instructions do not accept general ppc memory address expressions and thus the argument associated with the memory constraint cannot be used directly. instead, the memory constraint can be left as an argument that the asm does not actually use, and the address can be provided in a separate register constraint.
2014-07-19	fix broken constraints for powerpc atomic cas asm	Rich Felker	-1/+1
	the register constraint for the address to be accessed did not convey that the asm can access the pointed-to object. as far as the compiler could tell, the result of the asm was just a pure function of the address and the values passed in, and thus the asm could be hoisted out of loops or omitted entirely if the result was not used.
2013-08-11	add missing a_or_l to atomic.h for non-x86 archs	Rich Felker	-0/+5
	this is needed for recently committed sigaction code
2012-11-14	fix powerpc atomic compare-and-swap function	Rich Felker	-6/+7
	previous version did not compare at all; it was just a fancy atomic write. untested. further atomic fixes may be needed.
2012-11-14	update ppc atomic code to match the endian-agnostic version on other archs	Rich Felker	-14/+6

2012-11-13	PPC port cleaned up, static linking works well now.	rofl0r	-0/+124
