* Peter Zijlstra <peterz@infradead.org> wrote: > $ perf record --branch-filter u,any -e cycles:p ./branches 27 > $ perf annotate branches Btw., I'd really like to use this feature all the time, so could we please simplify this somewhat via a subcommand, via something like: perf record branches ./branches 27 or if 'record' subcommands are not possible anymore: perf record --branches ./branches 27 and in this case 'perf annotate' should automatically pick up the fact that the perf.data was done with --branches - i.e. the highlighting should be automagic. I.e. the only thing a user has to remember to use all this is a single '--branches' option to perf record - instead of a complex sequence for perf record and another sequence for perf annotate. It would also be nice to have 'perf top --branches', with the built-in annotation showing the highlighted branch heat map information and highlighting. Thanks, Ingo
