commit 6740a4e70e5d1b9d8e7fe41fd46dd5656d65dadf upstream.
perf report fails to add valid additional fields with -F when
used with branch or mem modes. Fix it.
Before patch:
$ perf record -b
$ perf report -b -F +srcline_from --stdio
Error:
Invalid --fields key: `srcline_from'
After patch:
$ perf report -b -F +srcline_from --stdio
# Samples: 8K of event 'cycles'
# Event count (approx.): 8784
...
Committer notes:
There was an inversion: when looking at branch stack dimensions (keys)
it was checking if the sort mode was 'mem', not 'branch'.
Fixes: aa6b3c9923 ("perf report: Make -F more strict like -s")
