Description Filip Pizlo 2014-01-08 11:56:11 PST 
Yes, disable the disabling.  Why?  Because LLVM's default is to use AVX if it's available, and WebKit can merely just ask LLVM to always avoid AVX even if it's available.  Hence WebKit can disable AVX, and we can disable the disabling of AVX to allow LLVM do just do its default.
