Could you also addAlthough mode in ix86_binary_operator_ok is ignored, V4SImode is less confusing. Also Operands 1 and 2 of sdot_prodv8hi must be register. Otherwise sse2_pmaddwd may fail when there are 2 memory operands.

PR target/31478 * config/i386/sse.md (sse2_umulv2siv2di3): Use V4SImode instead of V8HImode when calling ix86_binary_operator_ok. (sdot_prodv8hi): Operands 1 and 2 must be register.
Thanks, Uros.
