From 68d807586ba83d9cb77f12c8fb7c97ea438d34ad Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 2 Nov 2012 14:50:06 +0900 Subject: [PATCH] perf report: Postpone objdump check until annotation requested David reported that current perf report refused to run on a data file captured from a different machine because of objdump. Since the objdump tools won't be used unless annotation was requested, checking its presence at init time doesn't make sense.
