/* The purpose of this test is to catch edge cases when arguments are passed
   in regs and on the stack.  We test 16 cases, trying to catch multiple
   targets (some use 3 regs for argument passing, some use 12, etc.).
   We test both the arguments and the `lastarg' (the argument to va_start).  */
