Christophe Lyon <clyon at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |clyon at gcc dot gnu.org --- Comment #1 from Christophe Lyon <clyon at gcc dot gnu.org> --- Looks like a similar problem to PR99724 and PR98849. IIUC, iwmmxt only supports mult:V4HI (see mulv4hi3_iwmmxt in iwmmxt.md), so the condition ARM_HAVE_<MODE>_ARITH on define_expand "mul<mode>3" in vec-common.md is not strict enough.
