From f1cf602c16e9a93fd16705621f3430ec7ffe2c44 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 18 Oct 2011 14:37:34 -0200 Subject: perf hists: Don't format the percentage on hist_entry__snprintf We can't have color correctly set there because in libslang (and in a future GUI) the colors must be set on a separate function call, so move that part to a separate function and make the stdio fprintf function call it.
