From 09c0211c0bb0e40231e6ee9a35041d467ed72f16 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 4 May 2012 11:32:54 -0700 Subject: [PATCH] perf: Turn off compiler warnings for flex and bison generated files We don't know what types of warnings different versions of flex and bison combined with different versions of gcc is going to generate, so just punt and don't warn about anything. This fixes the build of perf for me on an openSUSE 12.1 system.
