From 058b4cc9af574c072988a38a7a5ee93df881e5aa Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 2 Apr 2012 12:59:01 -0300 Subject: [PATCH] perf annotate: Allow printing objdump line addr in different color And by default use "magenta" for it. Both the --stdio and --tui routines follow the same semantics.
