perf diff: Fix -o/--order option behavior (again)

2017-02-14T23:25:42+00:00

commit a1c9f97f0b64e6337d9cfcc08c134450934fdd90 upstream.

Commit 21e6d8428664 ("perf diff: Use perf_hpp__register_sort_field
interface") changed list_add() to perf_hpp__register_sort_field().

This resulted in a behavior change since the field was added to the tail
instead of the head.  So the -o option is mostly ignored due to its
order in the list.

This patch fixes it by adding perf_hpp__prepend_sort_field().

perf hists: Add support for header span

2016-08-23T18:37:33+00:00

Add span argument for header callback function.

The handling of this argument is completely in the hands of the
callback. The only thing the caller ensures is it's zeroed on the
beginning.

Omitting span skipping in hierarchy headers and gtk code.

The c2c code use this to span header lines based on the entries span
configuration.

2016-06-22T13:02:16+00:00

And do nothing, just like free(), to avoid having to test it in callers,
usually in error paths.

perf hists: Replace perf_evsel arg perf_hpp_fmt's header callback

2016-06-15T13:49:18+00:00

Replacing perf_evsel arg perf_hpp_fmt's header callback with hists
object.

None of the actual callbacks actually use evsel object, also this will
be helpful in future for non evsel related hist browsers.

perf tools: Set buildid dir under symfs when --symfs is provided

2016-05-20T14:43:58+00:00

This patch moves the reference of buildid dir to 'symfs/.debug' and
skips the local buildid dir when '--symfs' is given, so that every
single file opened by perf is relative to symfs directory now.
