Hi Steve, Thank you for your feedback! Are you going to mentor this specific Fortran GSoC project? You mentioned having a draft patch, and I would like to refine it as a starting point for the project!

First, some operating systems provide half-cycle trig functions in their libm. The initial patch tries to use libm functions if found, but in hindsight I think gfortran should simply provide its own implementations. Second, the patch needs to be cleaned up and rigorously tested. I haven't had time to do this. If you are looking for a relatively small and well-defined project, I'll suggest looking at implementations for the new intrinsic subprograms SPLIT() and TOKENIZE(). As far as I know, no one is working on these routines. -- steve On Mon, Mar 24, 2025 at 04:45:06PM +0000, Yuao Ma wrote: > Hello GCC Community, > > I hope this message finds you well.
