Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Yeah, before rnreg pass the fcmlt has p1 as destination and fsub/fsel use p0 (i.e. the parameter) while sel in between them uses p1. I see this behavior already in r10-5107-gb789efeae8c0620b8 and shortly before that it has been rejected with "variable-sized object may not be initialized" errors.
