[PATCH] ARC: perf: map 'ijmptak' to generic 'branches' event

2018-12-17 Thread Eugeniy Paltsev
Map 'ijmptak' event (all jump instructions that are taken) instead of 'ijmp' event (all jump and branch instructions) to generic 'branches' event as taken jump is more interesting metric for us due to the possible significantly greater overhead of taken jumps. 'ijmptak' event is available on both
