In this discussion, a `word' is 16 bits on the H8/300s, and 32 bits
on the H8/300H.
There are actually two ABI's here: -mquickcall (the default) and
-mno-quickcall. With -mno-quickcall, all arguments are passed on
the stack after the return address, word-aligned. With
-mquickcall, GCC tries to use r0 -- r2 to pass registers. Since
GCC doesn't indicate in the object file which ABI was used to
compile it, GDB only supports the default --- -mquickcall.
Here are the rules for -mquickcall, in detail:
Each argument, whether scalar or aggregate, is padded to occupy a
whole number of words. Arguments smaller than a word are padded at
the most significant end; those larger than a word are padded at
the least significant end.
The initial arguments are passed in r0 -- r2. Earlier arguments go in
lower-numbered registers. Multi-word arguments are passed in
consecutive registers, with the most significant end in the
lower-numbered register.
If an argument doesn't fit entirely in the remaining registers, it
is passed entirely on the stack. Stack arguments begin just after
the return address. Once an argument has overflowed onto the stack
this way, all subsequent arguments are passed on the stack.
The above rule has odd consequences. For example, on the h8/300s,
if a function takes two longs and an int as arguments:
- the first long will be passed in r0/r1,
- the second long will be passed entirely on the stack, since it
doesn't fit in r2,
- and the int will be passed on the stack, even though it could fit
in r2.
A weird exception: if an argument is larger than a word, but not a
whole number of words in length (before padding), it is passed on
the stack following the rules for stack arguments above, even if
there are sufficient registers available to hold it. Stranger
still, the argument registers are still `used up' --- even though
there's nothing in them.
So, for example, on the h8/300s, if a function expects a three-byte
structure and an int, the structure will go on the stack, and the
int will go in r2, not r0.
If the function returns an aggregate type (struct, union, or class)
by value, the caller must allocate space to hold the return value,
and pass the callee a pointer to this space as an invisible first
argument, in R0.
For varargs functions, the last fixed argument and all the variable
arguments are always passed on the stack. This means that calls to
varargs functions don't work properly unless there is a prototype
in scope.
Basically, this ABI is not good, for the following reasons:
- You can't call vararg functions properly unless a prototype is in scope.
- Structure passing is inconsistent, to no purpose I can see.
- It often wastes argument registers, of which there are only three
to begin with. */
