--- Comment #13 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:a5453c659bce698d80f5aebdab5ab0eba39b1ed6 commit r12-9153-ga5453c659bce698d80f5aebdab5ab0eba39b1ed6 Author: Andrew Pinski <apin...@marvell.com> Date: Thu Feb 9 16:03:54 2023 +0100 match.pd: When simplifying BFR of an insert, require a mode precision integral type [PR108688] The same problem as PR 88739 has crept in but this time in match.pd when simplifying bit_field_ref of an bit_insert. That is we are generating a BIT_FIELD_REF of a non-mode-precision integral type. PR tree-optimization/108688 * match.pd (bit_field_ref [bit_insert]): Avoid generating BIT_FIELD_REFs of non-mode-precision integral operands. * gcc.c-torture/compile/pr108688-1.c: New test. (cherry picked from commit 44f308e59bfa0f93ae05b17e257d8563c12399fd)
