--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> --- Created attachment 37741 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37741&action=edit Patch draft I've tried to sketch-up a simple patch that can do that. As the original source of the modified code is in LLVM project (which is merged to GCC), please create a PR in LLVM and I'll try to apply to patch to current LLVM trunk. The patch can be send eventually. Martin
