$ ~/perf stat -e 'slots,cycles,slots' true
WARNING: events were regrouped to match PMUs
Performance counter stats for 'true':
<not counted> cpu_core/slots/
<not supported> cpu_core/slots/
1,458,844 cpu_atom/cycles/
<not counted> cpu_core/cycles/ (0.00%)
0.001501970 seconds time elapsed
0.001621000 seconds user
0.000000000 seconds sys
Output is unexpected order.
I don't think there should be any reordering without a group.
