--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:4e3d3e40726e1b68bf52fa205c68495124ea60b8 commit r10-7237-g4e3d3e40726e1b68bf52fa205c68495124ea60b8 Author: Richard Biener <rguent...@suse.de> Date: Wed Mar 18 09:13:17 2020 +0100 middle-end/94188 fix fold of addr expression generation This adds a missing type conversion to build_fold_addr_expr and adjusts fallout - build_fold_addr_expr was used as a convenience to build an ADDR_EXPR but some callers do not expect the result to be simplified to something else. 2020-03-18 Richard Biener <rguent...@suse.de> PR middle-end/94188 * fold-const.c (build_fold_addr_expr): Convert address to correct type. * asan.c (maybe_create_ssa_name): Strip useless type conversions. * gimple-fold.c (gimple_fold_stmt_to_constant_1): Use build1 to build the ADDR_EXPR which we don't really want to simplify. * tree-ssa-dom.c (record_equivalences_from_stmt): Likewise. * tree-ssa-loop-im.c (gather_mem_refs_stmt): Likewise. * tree-ssa-forwprop.c (forward_propagate_addr_expr_1): Likewise. (simplify_builtin_call): Strip useless type conversions. * tree-ssa-strlen.c (new_strinfo): Likewise. * gcc.dg/pr94188.c: New testcase.
