574 | Setup the function arguments for calling a function in the inferior. | |
575 | In this discussion, a `word' is 16 bits on the H8/300s, and 32 bits | |
576 | on the H8/300H. | |
577 | ||
578 | There are actually two ABI's here: -mquickcall (the default) and | |
579 | -mno-quickcall. With -mno-quickcall, all arguments are passed on | |
580 | the stack after the return address, word-aligned. With | |
581 | -mquickcall, GCC tries to use r0 -- r2 to pass registers. Since | |
582 | GCC doesn't indicate in the object file which ABI was used to | |
583 | compile it, GDB only supports the default --- -mquickcall. | |
584 | ||
585 | Here are the rules for -mquickcall, in detail: | |
586 | ||
587 | Each argument, whether scalar or aggregate, is padded to occupy a | |
588 | whole number of words. Arguments smaller than a word are padded at | |
589 | the most significant end; those larger than a word are padded at | |
590 | the least significant end. | |
591 | ||
592 | The initial arguments are passed in r0 -- r2. Earlier arguments go in | |
593 | lower-numbered registers. Multi-word arguments are passed in | |
594 | consecutive registers, with the most significant end in the | |
595 | lower-numbered register. | |
596 | ||
597 | If an argument doesn't fit entirely in the remaining registers, it | |
598 | is passed entirely on the stack. Stack arguments begin just after | |
599 | the return address. Once an argument has overflowed onto the stack | |
600 | this way, all subsequent arguments are passed on the stack. | |
601 | ||
602 | The above rule has odd consequences. For example, on the h8/300s, | |
603 | if a function takes two longs and an int as arguments: | |
604 | - the first long will be passed in r0/r1, | |
605 | - the second long will be passed entirely on the stack, since it | |
606 | doesn't fit in r2, | |
607 | - and the int will be passed on the stack, even though it could fit | |
608 | in r2. | |
609 | ||
610 | A weird exception: if an argument is larger than a word, but not a | |
611 | whole number of words in length (before padding), it is passed on | |
612 | the stack following the rules for stack arguments above, even if | |
613 | there are sufficient registers available to hold it. Stranger | |
614 | still, the argument registers are still `used up' --- even though | |
615 | there's nothing in them. | |
616 | ||
617 | So, for example, on the h8/300s, if a function expects a three-byte | |
618 | structure and an int, the structure will go on the stack, and the | |
619 | int will go in r2, not r0. | |
620 | ||
621 | If the function returns an aggregate type (struct, union, or class) | |
622 | by value, the caller must allocate space to hold the return value, | |
623 | and pass the callee a pointer to this space as an invisible first | |
624 | argument, in R0. | |
625 | ||
626 | For varargs functions, the last fixed argument and all the variable | |
627 | arguments are always passed on the stack. This means that calls to | |
628 | varargs functions don't work properly unless there is a prototype | |
629 | in scope. | |
630 | ||
631 | Basically, this ABI is not good, for the following reasons: | |
632 | - You can't call vararg functions properly unless a prototype is in scope. | |
633 | - Structure passing is inconsistent, to no purpose I can see. | |
634 | - It often wastes argument registers, of which there are only three | |
635 | to begin with. */ | |
