re PR middle-end/17258 (gcc.c-torture/compile/20030224-1.c:16: internal compiler error: in expand_expr_addr_expr, at expr.c:6157)
PR middle-end/17258
* calls.c (initialize_argument_information): Tighten pass-through
conditions for pass-by-reference. Remove dead TARGET_EXPR code.
Use build_fold_addr_expr.
(emit_library_call_value_1): Use build_fold_addr_expr. Remove code
that assumes ADDR_EXPR allocates stack space.
* fold-const.c (build_fold_addr_expr_with_type): Look through
WITH_SIZE_EXPR.
