2012-11-08perf hists: Introduce hists__linkArnaldo Carvalho de Melo2-0/+61
That given two hists will find the hist_entries (buckets) in the second hists that are for the same bucket in the first and link them, then it will look for all buckets in the second that don't have a counterpart in the first and will create a dummy counterpart that will then be linked to the entry in the second. For multiple events this will be done pairing the leader with all the other events in the group, so that in the end the leader will have all the buckets in all the hists in a group, dummy or not while the other hists will be left untouched.

2012-11-05perf tools: Introduce struct hist_browser_timerNamhyung Kim8-67/+58
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.

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.
