Module: Mesa Branch: 17.0 Commit: 9ab1704f42bbaca8c43af51fbc08532ab62c1026 URL: http://cgit.freedesktop.org/mesa/mesa/commit/?id=9ab1704f42bbaca8c43af51fbc08532ab62c1026
Author: Michel Dänzer <[email protected]> Date: Thu Feb 9 13:00:03 2017 +0900 configure.ac: Drop LLVM compiler flags more radically Drop all -m*, -W*, -O*, -g* and -f* flags, with the exception of -fno-rtti, which must be used if it's part of the llvm-config --cxxflags output. We don't want LLVM to dictate the flags we use, and it can even cause build failures, e.g. if LLVM and Mesa are built with different compilers. While we're at it, eat any whitespace preceding dropped flags as well.
