hi,
this is v2 of diff command changes proposed in here:
https://lkml.org/lkml/2012/9/6/344
It's now rebased on new hists hpp* interface plus few
more additional changes.
I'm still testing/using it to come up with some proved
usability, but would be nice to have it in anyway.
v2 changes:
- based on hpp* interface
- patch 13/14 includes samples with no symbol in diff output
makes diff numbers looks the same as in report
- patch 14/14 displays empty space instead of zeros for
non paired samples makes the output more clear
Attached patches:
01/14 perf hists: Add struct hists pointer to struct hist_entry
02/14 perf diff: Refactor diff displacement possition info
03/14 perf hists: Separate overhead and baseline columns
04/14 perf tools: Removing hists pair argument from output path
05/14 perf diff: Add -b option for perf diff to display paired entries only
06/14 perf tool: Add hpp interface to enable/disable hpp column
07/14 perf diff: Add ratio computation way to compare hist entries
08/14 perf diff: Removing the total_period argument from output code
09/14 perf diff: Add option to sort entries based on diff computation
10/14 perf diff: Add weighted diff computation way to compare hist entries
11/14 perf diff: Add -p option to display period values for hist entries
12/14 perf diff: Add -F option to display formula for computation
13/14 perf diff: Include samples without symbol in overall stats
14/14 perf diff: Display empty space for non paired samples
