From 3780f4883b2f3319afe88bf3ddc73ef426851d49 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 29 May 2012 13:22:57 +0900 Subject: perf tools: Convert critical messages to ui__error() There were places where use ui__warning (or even fprintf) to show critical messages. This patch converts them to ui__error so that the front-end code can implement appropriate behavior.
