...ing operations. 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.

...and multiply. Bill Wendling is the one working on this, I forwarded your testcase to him so that he can focus on those operations first. > 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. Absolutely. Until now, there hasn't been anything pushing for MMX intrins...
