For things that don't work, do you have a small example program that shows what's wrong? Peter

Meaning one LLVM compiler cannot generate both

Now, I realize that __vector_size__ is a GCC extens...

Hi, I want to be able to write a function like this define <2 x double> @add(<2 x double> %a, <2 x double> %b) nounwind { %c = add <2 x double> %a, %b ret <2 x double> %c } and then call it from C code. What is the appropriate translation of the <2 x double> vector type into C? I've tried packed structs and "typedef double vec_double

Looking through the archives I have seen talk of making CPU specific optimisations for Vorbis, a la MMX/3DNow!/SSE. The feeling I gather is to wait until something is working well in C before committing to any kind of specific optimisation. What if oft used and needed DSP functions were identified and standardised DSP functionality be written for Vorbis? This would seperate the basically
