[PATCH 9/9] perf tools: Add symbolic events support for parse_events_error

Jiri Olsa
2015-04-22T19:12:16Z

Allowing symbolic events processing to report back error.

$ perf record -e 'cycles/period=krava/' ls
event syntax error: '../period=krava/'
\___ expected numeric value

$ perf record -e 'cycles/name=1/' ls
event syntax error: '..es/name=1/'
\___ expected string value
