--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 53438 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53438&action=edit gcc13-builtin-issignaling.patch Current WIP on the __builtin_issignaling. Still need to look at decimal arguments (if we need/want to deal with those) and add i386 issignalingxf2 optab so that it also handles pseudo numbers and add test coverage.
