--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:e2e01a893c1770e23ec1a573403688198c321b0e commit r16-3583-ge2e01a893c1770e23ec1a573403688198c321b0e Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Sep 4 18:52:47 2025 +0200 aarch64: Adjust aarch64/spaceship_1.C testcase for recent changes [PR121732] In r16-3414 libstdc++ changed ABI for (still experimental C++20) and uses unordered value -128 instead of 2. Generally the change improved code generation on all targets tested, see https://gcc.gnu.org/pipermail/gcc-patches/2025-August/693534.html for details. In r16-3474 I've adjusted the middle-end and backends to use that value. This apparently broke the spaceship_1.C test on aarch64 which scans the exact function bodies which are now different. The following patch adjusts the full body patterns to match. On these 2 routines, the generated code is 1 insn longer than in the past, so if you have ideas how to change the code generation for the common case of -1, 0, 1, -128 value, maybe it could be improved. 2025-09-04 Jakub Jelinek <ja...@redhat.com> PR testsuite/121732 PR target/117013 * g++.target/aarch64/spaceship_1.C: Adjust expected fn bodies for _Z8ss_floatff and _Z9ss_doubledd.
