I am attempting to create a vector version of sincos for PPC64. The relevant discussion thread is on the GLIBC libc-alpha mailing list. Navigate it beginning at https://sourceware.org/ml/libc-alpha/2019-09/msg00334.html
The intention is to reuse as much as possible from the existing GCC implementation of other libmvec functions. My questions are: Which function(s) in GCC; 1. Gather scalar function input arguments, from multiple loop iterations, into a single vector input argument for the vector function version? 2. Distribute scalar function outputs, to appropriate loop iteration result, from the single vector function output result? I am referring especially to vectorization of sin and cos. Thanks. Bert Tenjy.
