    Subject[PATCH v18 17/19] perf, tools: Make alias matching case-insensitive
    Date
    From: Andi Kleen <ak@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
