Vy Nguyen 0724050861 Reland [llvm-exegesis] Add benchmark latency option on X86 that uses LBR for more precise measurements. ... Starting with Skylake, the LBR contains the precise number of cycles between the two consecutive branches. Making use of this will hopefully make the measurements more precise than the existing methods of using RDTSC. Differential Revision: https://reviews.llvm.org/D77422 New change: check for existence of field `cycles` in perf_branch_entry before enabling this mode. This should prevent compilation errors when building for older kernel whose headers don't support it.		2020-07-27 12:38:05 -04:00
