566 /* Function: push_dummy_call
567 Setup the function arguments for calling a function in the inferior.
568 In this discussion, a `word' is 16 bits on the H8/300s, and 32 bits
571 There are actually two ABI's here: -mquickcall (the default) and
572 -mno-quickcall. With -mno-quickcall, all arguments are passed on
573 the stack after the return address, word-aligned. With
574 -mquickcall, GCC tries to use r0 -- r2 to pass registers. Since
575 GCC doesn't indicate in the object file which ABI was used to
576 compile it, GDB only supports the default --- -mquickcall.
578 Here are the rules for -mquickcall, in detail:
580 Each argument, whether scalar or aggregate, is padded to occupy a
581 whole number of words. Arguments smaller than a word are padded at
582 the most significant end; those larger than a word are padded at
583 the least significant end.
585 The initial arguments are passed in r0 -- r2. Earlier arguments go in
586 lower-numbered registers. Multi-word arguments are passed in
587 consecutive registers, with the most significant end in the
588 lower-numbered register.
590 If an argument doesn't fit entirely in the remaining registers, it
591 is passed entirely on the stack. Stack arguments begin just after
592 the return address. Once an argument has overflowed onto the stack
593 this way, all subsequent arguments are passed on the stack.
595 The above rule has odd consequences. For example, on the h8/300s,
596 if a function takes two longs and an int as arguments:
597 - the first long will be passed in r0/r1,
598 - the second long will be passed entirely on the stack, since it
600 - and the int will be passed on the stack, even though it could fit
603 A weird exception: if an argument is larger than a word, but not a
604 whole number of words in length (before padding), it is passed on
605 the stack following the rules for stack arguments above, even if
606 there are sufficient registers available to hold it. Stranger
607 still, the argument registers are still `used up' --- even though
608 there's nothing in them.
610 So, for example, on the h8/300s, if a function expects a three-byte
611 structure and an int, the structure will go on the stack, and the
612 int will go in r2, not r0.
614 If the function returns an aggregate type (struct, union, or class)
615 by value, the caller must allocate space to hold the return value,
616 and pass the callee a pointer to this space as an invisible first
619 For varargs functions, the last fixed argument and all the variable
620 arguments are always passed on the stack. This means that calls to
621 varargs functions don't work properly unless there is a prototype
624 Basically, this ABI is not good, for the following reasons:
625 - You can't call vararg functions properly unless a prototype is in scope.
626 - Structure passing is inconsistent, to no purpose I can see.
627 - It often wastes argument registers, of which there are only three
