* builtins.c (expand_builtin_memcpy): Call force_operand on
expressions and use simplify_gen_binop to create the addition.
* gcc.c-torture/compile/20030504-1.c: New test case.
The test case - now called 20030518-1.c - fails on sh-elf with an
ICE.
simplify_gen_binary is called with mode=VOIDmode, which is eventually
passed down to trunc_int_for_mode.
