Adhemerval Zanella	4b45943a6f	powerpc: Add adaptive elision to rwlocks ... This patch adds support for lock elision using ISA 2.07 hardware transactional memory for rwlocks. The logic is similar to the one presented in pthread_mutex lock elision.	2015-01-12 06:30:54 -05:00
Adhemerval Zanella	8d2c0a593b	powerpc: Add the lock elision using HTM ... This patch adds support for lock elision using ISA 2.07 hardware transactional memory instructions for pthread_mutex primitives. Similar to s390 version, the for elision logic defined in 'force-elision.h' is only enabled if ENABLE_LOCK_ELISION is defined. Also, the lock elision code should be able to be built even with a compiler that does not provide HTM support with builtins. However I have noted the performance is sub-optimal due scheduling pressures.	2015-01-12 06:30:19 -05:00
