PR middle-end/29215
* builtins.c (SLOW_UNALIGNED_ACCESS): Define if not defined.
(fold_builtin_memory_op): Handle even the case where just one
of src and dest is an address of a var decl component, using
TYPE_REF_CAN_ALIAS_ALL pointers. Remove is_gimple_min_invariant
and readonly_data_expr src check.
* tree-ssa-sccvn.c (DFS): Use clear_and_done_ssa_iter to shut
up warnings.
* trans-array.c (trans_array_constructor_value,
gfc_build_constant_array_constructor): Fill in TREE_PURPOSE.
* gfortran.dg/array_memcpy_3.f90: Adjust pattern to match even
memcpy optimized into ref-all store.
* gcc.dg/pr29215.c: New test.
