--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:4f9a9c26da2fe429d11dc96939dcb135b20d67d7 commit r16-6994-g4f9a9c26da2fe429d11dc96939dcb135b20d67d7 Author: Richard Biener <[email protected]> Date: Fri Jan 23 09:58:50 2026 +0100 middle-end/123775 - add missing expand_vec_cond_expr_p to patterns This adds a missing check on supportability of a VEC_COND_EXPR to a match.pd pattern. The existing conditions, in particular known_eq of TYPE_VECTOR_SUBPARTS, is not enough to distinguish VNx4SImode from V4SImode with -msve-vector-bits=128. PR middle-end/123775 * match.pd ((view_convert (vec_cond ...))): Make sure the resulting vec_cond can be expanded. * gcc.target/aarch64/sve2/pr123775.c: New testcase.
