Re: __simd_sto confusion

That's a shame. I've read that each compiler has his own quirks and not support everything dmd supports. I do want to keep the code as portable as possible. Guess I'll try using inline assembler and runtime checks for the right cpu architecture. Thanks for the help people.

Re: __simd_sto confusion

This is a bug in overload resolution when __vector(void[16]) is involved. You can go around it by changing float4 to void16, only to run into an internal compiler error: backend/gother.c 988 So file a bug for both @ issues.dlang.org Also it looks like DMD wants you to use the return value of the
