[root@mica ~]# perf stat -x, -a -A -- sleep 1 -B option not supported with -x
usage: perf stat [<options>] [<command>]
-e, --event <event> event selector. use 'perf list' to list available events -i, --no-inherit child tasks do not inherit counters -p, --pid <n> stat events on existing process id
Guess we'll have to disable big_num automatically when -x is specified, but at the same time notice if the user _explicitely_ asked for -B.
I'll fix this now.
