Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rguenth at gcc dot gnu.org --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- You can try if match.pd is "preprocessed enough" to make use of macros. vec_perm:c cannot be done, "selective" :c on a for iterator is also not possible. If you have an idea for a syntax to express the "iteration" please share it.
