| H A D | evsel.h | 2cee77c4 Mon May 30 09:55:59 CDT 2011 David Ahern <dsahern@gmail.com> perf stat: clarify unsupported events from uncounted events
perf stat continues running even if the event list contains counters
that are not supported. The resulting output then contains <not counted>
for those events which gets confusing as to which events are supported,
but not counted and which are not supported.
