-/* Function: push_arguments
-   Setup the function arguments for calling a function in the inferior.
-
-   On the Hitachi 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.
-
-   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.
-
-   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.   */

-/* On the sh4, the DRi pseudo registers are problematic if the target
-   is little endian. When the user writes one of those registers, for
-   instance with 'ser var $dr0=1', we want the double to be stored
-   like this: 
-   fr0 = 0x00 0x00 0x00 0x00 0x00 0xf0 0x3f 
-   fr1 = 0x00 0x00 0x00 0x00 0x00 0x00 0x00 
-
-   This corresponds to little endian byte order & big endian word
-   order.  However if we let gdb write the register w/o conversion, it
-   will write fr0 and fr1 this way:
-   fr0 = 0x00 0x00 0x00 0x00 0x00 0x00 0x00
-   fr1 = 0x00 0x00 0x00 0x00 0x00 0xf0 0x3f
-   because it will consider fr0 and fr1 as a single LE stretch of memory.
-   
-   To achieve what we want we must force gdb to store things in
-   floatformat_ieee_double_littlebyte_bigword (which is defined in
-   include/floatformat.h and libiberty/floatformat.c.
-
-   In case the target is big endian, there is no problem, the
-   raw bytes will look like:
-   fr0 = 0x3f 0xf0 0x00 0x00 0x00 0x00 0x00
-   fr1 = 0x00 0x00 0x00 0x00 0x00 0x00 0x00 
-
-   The other pseudo registers (the FVs) also don't pose a problem
-   because they are stored as 4 individual FP elements. */
