From a64489c56c307bf0955f0489158c5ecf6aa10fe2 Mon Sep 17 00:00:00 2001 From: Jin Yao Date: Sun, 26 Mar 2017 04:34:26 +0800 Subject: perf report: Find the inline stack for a given address It would be useful for perf to support a mode to query the inline stack for a given callgraph address. This would simplify finding the right code in code that does a lot of inlining. The srcline.c has contained the code which supports to translate the address to filename:line_nr. This patch just extends the function to let it support getting the inline stacks. It introduces the inline_list which will store the inline function result (filename:line_nr and funcname). If BFD lib is not supported, the result is only filename:line_nr.
