From 78f7defedbb4da73b9a07635c357c1afcaa55c8f Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 4 Feb 2011 09:45:46 -0200 Subject: perf annotate: Move annotate functions to util/ They will be used by perf top, so that we have just one set of routines to do annotation. Rename "struct sym_priv" to "struct annotation", etc, to clarify this code a bit. Rename "struct sym_ext" to "struct source_line", to give it a meaningful name, that clarifies that it is a the result of an addr2line call, that is sorted by percentage one particular source code line appeared in the annotation. And since we're moving things around also rename 'sym_hist->ip' to 'sym_hist->addr' as we want to do data structure annotation at some point.
