2014-03-18perf symbols: Record the reason for filtering an address_locationNamhyung Kim
By turning the addr_location->filtered member from a boolean to a u8 bitmap, reusing (and extending) the hist_filter enum for that. This patch doesn't change the logic at all, as it keeps the meaning of al->filtered !0 to mean that the entry _was_ filtered, so no change in how this value is interpreted needs to be done at this point. This will be soon used in upcoming patches.

Those functions need evsel to investigate event group and it's passed via hpp->ptr. However as it can be missed easily so it's better to pass it via an argument IMHO.

2012-11-08perf hists: Introduce hists__linkArnaldo Carvalho de Melo
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.

Create a script browser, so that user can check all the available scripts for current perf data file and run them inside the main perf report or annotation browsers, for all perf samples or for samples belong to one thread/symbol. Please be noted: current script browser is only for report use, and doesn't cover the record phase, IOW it must run against one existing perf data file. The work flow is, users can use function key to list all the available scripts for current perf data file in system and chose one, which will be executed with popen("perf script -s xxx.xx",) and all the output lines are put into one ui browser, pressing 'q' or left arrow key will make it return to previous browser.
