--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alex Coplan <acop...@gcc.gnu.org>: https://gcc.gnu.org/g:277e1f30a5e4e634304a7b8a532825119f0ea47f commit r13-5718-g277e1f30a5e4e634304a7b8a532825119f0ea47f Author: Alex Coplan <alex.cop...@arm.com> Date: Mon Feb 6 14:32:21 2023 +0000 aarch64: Fix up bfmlal lane pattern [PR104921] As the testcase shows, this pattern had an incorrect constraint leading to GCC's output getting rejected by the assembler. This patch fixes the constraint accordingly. The test is split into two: one that can run without bf16 support from the assembler and another that checks that the output actually assembles when such support is available. Bootstrapped/regtested on aarch64-linux-gnu. OK for GCC 13? Or better to wait for next stage 1? What about backports? Thanks, Alex gcc/ChangeLog: PR target/104921 * config/aarch64/aarch64-simd.md (aarch64_bfmlal<bt>_lane<q>v4sf): Use correct constraint for operand 3. gcc/testsuite/ChangeLog: PR target/104921 * gcc.target/aarch64/pr104921-1.c: New test. * gcc.target/aarch64/pr104921-2.c: New test. * gcc.target/aarch64/pr104921.x: Include file for new tests.
