--- Comment #11 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:a9a425df628ab80374cc6a132d39e470bc78c8bc commit r13-8480-ga9a425df628ab80374cc6a132d39e470bc78c8bc Author: Richard Biener <rguent...@suse.de> Date: Fri Feb 23 16:06:05 2024 +0100 middle-end/114070 - folding breaking VEC_COND expansion The following properly guards the simplifications that move operations into VEC_CONDs, in particular when that changes the type constraints on this operation. This needed a genmatch fix which was recording spurious implicit fors when tcc_comparison is used in a C expression. PR middle-end/114070 * genmatch.cc (parser::parse_c_expr): Do not record operand lists but only mark operators used. * match.pd ((c ? a : b) op (c ? d : e) --> c ? (a op d) : (b op e)): Properly guard the case of tcc_comparison changing the VEC_COND value operand type. * gcc.dg/torture/pr114070.c: New testcase.
