4 Subject: [PATCH 081/200] * config/i386/sse.md: Update copyright year.
5 (avx_cmp<ssescalarmodesuffix><mode>3): Add missing output
7 (*vec_concatv2sf_avx): Fix wrong register constraint in
8 alternative 3 of operand 1.
9 (*vec_set<mode>_0_avx): Avoid combining registers from different
10 units in a single alternative.
11 (*vec_set<mode>_0_sse4_1): Ditto.
12 (*vec_set<mode>_0_sse2): Ditto.
13 (vec_set<mode>_0): Ditto.
14 (sse2_storehpd): Ditto.
15 (sse2_loadhpd): Ditto.
16 (sse4_1_insertps): Use nonimmediate_operand for operand 2.
17 * config/i386/predicates.md (sse_comparison_operator): Do not
18 define as special predicate.
