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