From 6745d8ea825966b0956c691cf7fccc13debedc39 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 12 Apr 2016 15:26:13 +0200 Subject: perf script: Add stackcollapse.py script Add stackcollapse.py script as an example of parsing call chains, and also of using optparse to access command line options. The flame graph tools include a set of scripts that parse output from various tools (including "perf script"), remove the offsets in the function and collapse each stack to a single line. The website also says "perf report could have a report style [...] that output folded stacks directly, obviating the need for stackcollapse-perf.pl", so here it is. This script is a Python rewrite of stackcollapse-perf.pl, using the perf scripting interface to access the perf data directly from Python.
