--- Comment #19 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:20ebcaf826c91ddaf2aac35417ec1e5e6d31ad50 commit r13-8695-g20ebcaf826c91ddaf2aac35417ec1e5e6d31ad50 Author: Richard Biener <rguent...@suse.de> Date: Fri Apr 26 15:47:13 2024 +0200 middle-end/114734 - wrong code with expand_call_mem_ref When expand_call_mem_ref looks at the definition of the address argument to eventually expand a &TARGET_MEM_REF argument together with a masked load it fails to honor constraints imposed by SSA coalescing decisions. The following fixes this. PR middle-end/114734 * internal-fn.cc (expand_call_mem_ref): Use get_gimple_for_ssa_name to get at the def stmt of the address argument to honor SSA coalescing constraints. (cherry picked from commit 4d3a5618de5a949c61605f545f90e81bc0000502)
