[LLVMdev] A few inline assembly questions
...tions. llvm-gcc doesn't seem to support mmx intrinsics which makes Qt compiled with llvm-gcc quite a bit slower when it comes to graphics. test2.cpp shows in essence what we're doing in Qt. we basically have a very simple class that defines simple static methods like negate/add/byte_mul/interpolate_pixel. now the question is if there is any way of getting code like this to utilize vector instructions with llvm-gcc. i wouldn't mind having llvm specific path there as long as it works.
