lowpart_subreg might fail in some cases when trying to create paradoxical SUBREGs. Use force_reg on input operand, use new temporary output operand and emit move into the destination afterwards. Also, replace simplify_gen_subreg (Mx, op, My, 0) with equivalent lowpart_subreg (Mx, op, My). 2021-12-29 Uroš Bizjak <ubizjak@gmail.com> gcc/ChangeLog: * config/i386/sse.md (vec_pack<floatprefix>_float_<mode>): Perform gen_avx512dq_float<floatunssuffix>v2div2sf2 into a pseudo and emit move insn into operands[0].
