Hello! Attached patch fixes PR 64688. Operand constraints were wrong for reg-to-vec targets. The patch also fixes PR 64477. 2015-22-01 Uros Bizjak <ubizjak@gmail.com> PR target/64688 PR target/64477 * config/i386/sse.md (vec_set<mode>_0): Use (Yi/r/C) constraints for alternative 3. testsuite/ChangeLog: 2015-22-01 Uros Bizjak <ubizjak@gmail.com> PR target/64688 * g++.dg/pr64688.C: New test. Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}. Committed to mainline, will be backported to release branches. Uros.
