Author: jakub Date: Thu Nov 20 21:35:03 2008 New Revision: 142061 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=142061 Log: 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.
