perf_counter tools: Introduce alias member in event_symbol
By introducing alias member in event_symbol : 1. duplicate lines are removed, like: cpu-cycles and cycles branch-instructions and branches context-switches and cs cpu-migrations and migrations 2. We can also add alias for another events. Now ./perf list looks like : List of pre-defined events (to be used in -e): cpu-cycles OR cycles [Hardware event] instructions [Hardware event] cache-references [Hardware event] cache-misses [Hardware event] branch-instructions OR branches [Hardware event] branch-misses [Hardware event] bus-cycles [Hardware event] cpu-clock [Software event] task-clock [Software event] page-faults [Software event] faults [Software event] minor-faults [Software event] major-faults [Software event] context-switches OR cs [Software event] cpu-migrations OR migrations [Software event] rNNN [raw hardware event descriptor] Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> LKML-Reference: <1245669268.17153.8.camel@localhost.localdomain> Signed-off-by: Ingo Molnar <mingo@elte.hu>
