Paul Murphy fadd2ad9cc powerpc: Optimize lock elision for pthread_mutex_t ... With TLE enabled, the adapt count variable update incurs an 8% overhead before entering the critical section of an elided mutex. Instead, if it is done right after leaving the critical section, this serialization can be avoided. This alters the existing behavior of __lll_trylock_elision as it will only decrement the adapt_count if it successfully acquires the lock. * sysdeps/unix/sysv/linux/powerpc/elision-lock.c (__lll_lock_elision): Remove adapt_count decrement... * sysdeps/unix/sysv/linux/powerpc/elision-trylock.c (__lll_trylock_elision): Likewise. * sysdeps/unix/sysv/linux/powerpc/elision-unlock.c (__lll_unlock_elision): ... to here. And utilize new adapt_count parameter. * sysdeps/unix/sysv/linux/powerpc/lowlevellock.h (__lll_unlock_elision): Update to include adapt_count parameter. (lll_unlock_elision): Pass pointer to adapt_count variable.		2015-10-15 18:56:10 -03:00
