--- Comment #3 from Martin Jambor <jamborm at gcc dot gnu.org> --- (In reply to Richard Biener from comment #2) > It seems to me this is a task for SRA (again...) which should be more > forgiving to select stmts requiring address-taking of locals but only > when they are not rewritten plus analyzing memcpy, memset (and other > select builtins) as to their effect. With https://gcc.gnu.org/pipermail/gcc-patches/2023-November/636836.html SRA is more forgiving to address-taken candidates like this but indeed it also needs to understand memcpy and similar builtins, which it does not. Representing it in GIMPLE might almost work, though we probably need to handle that case in build_ref_for_offset to create MEM_REFs with the appropriate alias access type.
