--- Comment #9 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-16 branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:004b053c4b60bdbf946168773d15f5971a28cd1b commit r16-9667-g004b053c4b60bdbf946168773d15f5971a28cd1b Author: Richard Biener <[email protected]> Date: Mon Aug 24 15:28:42 2026 +0200 tree-optimization/127000 - revise (T *)(ptr - ptr_cst) pattern The following revises the earlier fix which was avoiding build_fold_addr_expr_with_type. Instead the following applies the GENERIC simplification that this function should have done to the pattern directly, canonicalizing (T *)(ptr - ptr_cst) to (T *)ptr p+ cst. The pattern was originally added with r10-7127-gcb99630f254aae. PR tree-optimization/127000 * match.pd ((T *)(ptr - ptr_cst)): Canonicalize directly to (T *)ptr p+ cst. (cherry picked from commit c5d24759ba5e470f6fb75e251b84ec8fcb33db07)
