From: Andi Kleen <a...@linux.intel.com>
Make alias matching the events parser case-insensitive. This is useful
with the JSON events. perf uses lower case events, but the CPU manuals
generally use upper case event names. The JSON files use lower
case by default too. But if we search case insensitively then
users can cut-n-paste the upper case event names.
So the following works:
% perf stat -e BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL true
Performance counter stats for 'true':
305 BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL
0.000492799 seconds time elapsed
