928e48af CV |
568 | In this discussion, a `word' is 16 bits on the H8/300s, and 32 bits |
569 | on the H8/300H. | |
570 | ||
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. | |
577 | ||
578 | Here are the rules for -mquickcall, in detail: | |
579 | ||
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. | |
584 | ||
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. | |
589 | ||
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. | |
594 | ||
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 | |
599 | doesn't fit in r2, | |
600 | - and the int will be passed on the stack, even though it could fit | |
601 | in r2. | |
602 | ||
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. | |
609 | ||
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. | |
613 | ||
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 | |
617 | argument, in R0. | |
618 | ||
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 | |
622 | in scope. | |
623 | ||
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 | |
628 | to begin with. */ | |
