From 66bd8424cc05e800db384053bf7ab967e4658468 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 28 Oct 2009 21:51:21 -0200 Subject: perf tools: Delay loading symtabs till we hit a map with it So that we can have a quicker start on perf top and even speedups in the other tools, as we can have maps with no hits, so no need to load its symtabs.
