[PATCH 0/4] perf annotate: Fixes for line numbers and Introduce source_code
From: Taeung Song
Date: Wed Feb 22 2017 - 05:08:48 EST
Currently perf-annotate have several problems.
- Wrong line numbers on perf-annotate (both stdio and TUI)
- Wrong sum of overhead(percent) matching source lines
- It's so confusing that the output is mixed with
both source code and assembly code. (related to depending on 'objdump -S')
So fix them regarding wrong line numbers
and Introduce new source_code collecting actual code,
not depending on 'objdump -S'.
In near future, I have a plan for new reable annotate view
base on source code (per function(sym)) using the 'struct source_code'. :)
I'd appreciate some feedback.
(Current v1 don't consider improvement of performance of annotate
and don't make code of annotate more compact so I'll consider them in v2)
Taeung Song (4):
perf annotate: Remove needless regular expression for filename:linenr
perf annotate: Align filename:linenr and more correct summary
perf annotate: Change the method counting line numbers
perf annotate: Introduce source_code to collect actual code
