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