perf bench: Modify builtin-pipe.c for processing common options
This patch modifies builtin-pipe.c for processing common options. The first option added is "--format". Users of perf bench will be able to specify output style by --format. Usage example: % ./perf bench sched pipe # with no style specify (executing 1000000 pipe operations between two tasks) Total time:5.855 sec 5.855061 usecs/op 170792 ops/sec % ./perf bench --format=simple sched pipe # specified simple 5.988 Signed-off-by: Hitoshi Mitake <mitake@dcl.info.waseda.ac.jp> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> LKML-Reference: <1257808802-9420-5-git-send-email-mitake@dcl.info.waseda.ac.jp> Signed-off-by: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org>
