4100 * combine.c (distribute_notes): If i3 is a noreturn call,
4101 allow old_size to be equal to args_size and make sure the
4102 noreturn call gets REG_ARGS_SIZE note.
4103 * expr.c (fixup_args_size_notes): Put REG_ARGS_SIZE notes
4104 on noreturn calls even when the delta is 0.
4106 2012-01-11 Nathan Sidwell <nathan@acm.org>

4116 * gimple.h (gimplify_body): Remove first argument.

4118 pointer set here, instead just pass DATA to walk_tree.
4119 (unshare_body): Remove BODY_P argument and adjust. Create the pointer
4120 set here and invoke copy_if_shared on the size trees of DECL_RESULT.
4121 (unvisit_body): Likewise, but with unmark_visited.
4122 (gimplify_body): Remove BODY_P argument and adjust.
4123 (gimplify_function_tree): Adjust call to gimplify_body.

4132 (build_function_decl_skip_args): Add SKIP_RETURN parameter and
4133 pass it to build_function_type_skip_args.
4134 * cgraph.h (cgraph_function_versioning): Add boolean parameter.
4135 (tree_function_versioning): Likewise.
4136 * cgraph.c (cgraph_create_virtual_clone): Adjust call to
4137 build_function_decl_skip_args.
