Its not 'diff' specific and will be useful for other use cases, like bucketizing multiple events in a single session.

We want to match more than two hists, so that we can match more than two perf.data files and moreover, match hist_entries (buckets) in multiple events in a group. So the "baseline"/"leader" will instead of a ->pair pointer, use a list_head, that will link to the pairs and hists__match use it. Following that perf_evlist__link will link the hists in its evsel groups.

Arnaldo reported that annotation during perf top resulted in a segfault. It was because the env->arch was NULL and we don't set it for a live session. In fact, no need to look up objdump in this case since we can use system's default (native) objdump. Reported-by:

Output of /proc/<pid>/maps contains helpful information to anonymous mappings like stack, heap, ...

David reported that current perf report refused to run on a data file captured from a different machine because of objdump. Since the objdump tools won't be used unless annotation was requested, checking its presence at init time doesn't make sense. Reported-by:

Currently various hist browser functions receive 3 arguments for refreshing histogram but only used from a few places. Also it's only for perf top command so that it can be NULL for other (and probably most) cases. Pack them into a struct in order to reduce number of those unused arguments. This is a mechanical change and does not intend a functional change. Signed-off-by:

David reported that perf report for i686 target data on x86_64 host failed to work because it tried to find out cross-compiled objdump. However objdump for x86_64 is compatible to i686 so that it doesn't need to do it at all. To prevent similar artifacts, normalize arch name when comparing host and file architectures. Reported-by:

The idea is run perf session with kidnapping sys_perf_event_open function. For each sys_perf_event_open call we store the perf_event_attr data to the file to be checked later against what we expect. You can run this by: $ python ./tests/attr.py -d ./tests/attr/ -p ./perf -v v2 changes: - preserve errno value in the hook Signed-off-by:
