/* The ABI says:

   Aggregate types not bigger than 8 bytes that have the same size and
   alignment as one of the integer scalar types are returned in the
   same registers as the integer type they match.

   For example, a 2-byte aligned structure with size 2 bytes has the
   same size and alignment as a short int, and will be returned in R0.
   A 4-byte aligned structure with size 8 bytes has the same size and
   alignment as a long long int, and will be returned in R0 and R1.

   When an aggregate type is returned in R0 and R1, R0 contains the
   first four bytes of the aggregate, and R1 contains the
   remainder. If the size of the aggregate type is not a multiple of 4
   bytes, the aggregate is tail-padded up to a multiple of 4
   bytes. The value of the padding is undefined. For little-endian
   targets the padding will appear at the most significant end of the
   last element, for big-endian targets the padding appears at the
   least significant end of the last element.

   All other aggregate types are returned by address. The caller
   function passes the address of an area large enough to hold the
   aggregate value in R2. The called function stores the result in
   this location.

   To reiterate, structs smaller than 8 bytes could also be returned
   in memory, if they don't pass the "same size and alignment as an
   integer type" rule.

   For example, in

   struct s { char c[3]; } wibble;
   struct s foo(void) {  return wibble; }

   the return value from foo() will be in memory, not
   in R0, because there is no 3-byte integer type.

   Similarly, in 

   struct s { char c[2]; } wibble;
   struct s foo(void) {  return wibble; }

   because a struct containing two chars has alignment 1, that matches
   type char, but size 2, that matches type short.  There's no integer
   type that has alignment 1 and size 2, so the struct is returned in
   memory.

/* Function: push_dummy_call (formerly push_arguments)
   Setup the function arguments for calling a function in the inferior.

   On the Renesas SH architecture, there are four registers (R4 to R7)
   which are dedicated for passing function arguments.  Up to the first
   four arguments (depending on size) may go into these registers.
   The rest go on the stack.

   MVS: Except on SH variants that have floating point registers.
   In that case, float and double arguments are passed in the same
   manner, but using FP registers instead of GP registers.

   Arguments that are smaller than 4 bytes will still take up a whole
   register or a whole 32-bit word on the stack, and will be 
   right-justified in the register or the stack word.  This includes
   chars, shorts, and small aggregate types.

   Arguments that are larger than 4 bytes may be split between two or 
   more registers.  If there are not enough registers free, an argument
   may be passed partly in a register (or registers), and partly on the
   stack.  This includes doubles, long longs, and larger aggregates. 
   As far as I know, there is no upper limit to the size of aggregates 
   that will be passed in this way; in other words, the convention of 
   passing a pointer to a large aggregate instead of a copy is not used.

   MVS: The above appears to be true for the SH variants that do not
   have an FPU, however those that have an FPU appear to copy the
   aggregate argument onto the stack (and not place it in registers)
   if it is larger than 16 bytes (four GP registers).

   An exceptional case exists for struct arguments (and possibly other
   aggregates such as arrays) if the size is larger than 4 bytes but 
   not a multiple of 4 bytes.  In this case the argument is never split 
   between the registers and the stack, but instead is copied in its
   entirety onto the stack, AND also copied into as many registers as 
   there is room for.  In other words, space in registers permitting, 
   two copies of the same argument are passed in.  As far as I can tell,
   only the one on the stack is used, although that may be a function 
   of the level of compiler optimization.  I suspect this is a compiler
   bug.  Arguments of these odd sizes are left-justified within the 
   word (as opposed to arguments smaller than 4 bytes, which are 
   right-justified).

   If the function is to return an aggregate type such as a struct, it 
   is either returned in the normal return value register R0 (if its 
   size is no greater than one byte), or else the caller must allocate
   space into which the callee will copy the return value (if the size
   is greater than one byte).  In this case, a pointer to the return 
   value location is passed into the callee in register R2, which does 
   not displace any of the other arguments passed in via registers R4
   to R7.   */
