From 9f5a5d541d5c1ff2e440791ba8ff44d0233daeb4 Mon Sep 17 00:00:00 2001 From: Chad Versace Date: Thu, 9 Aug 2012 12:59:22 -0700 Subject: [PATCH] mesa: Remove C++11 narrowing warnings Add -Wno-narrowing to CXXFLAGS for gcc. It is safe to add this flag even for versions of gcc that don't recognize it. From the GCC Manual [1]: "[GCC] allows the use of new -Wno- options with old compilers". This removes warnings of the form warning: narrowing conversion of X from 'int' to 'float' inside { } is ill-formed in C++11 [-Wnarrowing] in ff_fragment_shader.cpp and gen6_blorp.cpp of the form. When building i965, I observed no other difference in the build output.
