Introduce a new option to print trace output to files named by the
monitored events and update perf-script documentation accordingly.
Shown below is output of perf script command with the newly introduced
option.
$perf record -e cycles -e context-switches -ag -- sleep 10
$perf script --per-event-dump
$ls /
cycles.stacks context-switches.stacks
Without per-event-dump support, drawing flamegraphs for different events
is really hard. You can only monitor one event at a time for perf record.
Using this option, we can get the trace output files named by the monitored
events, and could draw flamegraphs according to the event's name.
yuzhoujian (3):
Add a new element for the struct perf_tool, and add the
--per-event-dump option for perf script
Makes all those related functions receive the FILE pointer
Replace printf with fprintf for all the output functions

Not going to argue for or against this patch, but I think the reasoning you
give in your commit message is outdated:
https://github.com/brendangregg/FlameGraph/commit/
4b7b3169ed303d33fb710e1b9de235b84cc119d3
I.e. with a recent FlameGraph, you can generate flame graphs for different
events just fine, without any intermediate step.
Cheers

That change should be dropped. I recall Arnaldo saying this feature does
not need a short option and the above is not how it should done anyways.

The subject of this patch is replacing printf and stdout with fprintf
and a given fp. Please keep it to that one change. Meaning the above
setting of fp something other than stdout should be a separate patch.
And it would be best to have the fp selection in a helper, versus the
same change in so many places.
