We currently don't support storing multiple session in perf.data,
so we can't allow -r option in stat record.
$ perf stat -e cycles -r 2 record ls
Cannot use -r option with perf stat record.
Committer note:
Before this patch we would a perf.data file such as:
$ perf stat -e cycles -r 2 record ls
<SNIP>
Performance counter stats for 'ls' (2 runs):
3,935,236 cycles
0.002353261 seconds time elapsed ( +- 4.76% )
$ perf report -D | grep PERF_RECORD | grep ROUND
0xf0 [0]: failed to process type: 16
Error:
