--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Uros Bizjak <u...@gcc.gnu.org>: https://gcc.gnu.org/g:72c68d7ad90221075102f08f22256d0b4a7631b3 commit r12-6081-g72c68d7ad90221075102f08f22256d0b4a7631b3 Author: Uros Bizjak <ubiz...@gmail.com> Date: Mon Dec 20 21:15:50 2021 +0100 i386: Fix <sse2p4_1>_pinsr<ssemodesuffix> and its splitters [PR103772] The clever trick to duplicate the value of the input operand into itself proved not so clever after all. The splitter should not clobber the input operand in any case, since the register can hold the value outside the HImode lowpart when accessed as subreg. Use the standard earlyclobber approach instead. The testcase fails with avx2 ISA, but I was not able to create the testcase that wouldn't require -mavx512fp16 compile flag. 2021-12-20 Uroš Bizjak <ubiz...@gmail.com> gcc/ChangeLog: PR target/103772 * config/i386/sse.md (<sse2p4_1>_pinsr<ssemodesuffix>): Add earlyclobber to (x,x,x,i) alternative. (<sse2p4_1>_pinsr<ssemodesuffix> peephole2): Remove. (<sse2p4_1>_pinsr<ssemodesuffix> splitter): Use output operand as a temporary register. Split after reload_completed.
