I have a question about shufps instructions. So what kind of C code would usually generate shufps by the compiler?
Thank you for your help!
I'm sure we can't guess your target without hints. Code which gathers or scatters elements to and from a packed vector under SSE2 code option, possibly with the help of #pragma vector always. Setting SSE4 options would promote newer instructions for the same purpose.
Sorry for the confusion. I meant to ask what kind of C code could be possibly translated into shufps by the compiler. I think the problem has been solved. Thank you guys! :-)
