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. */ - -static CORE_ADDR -h8300_push_dummy_call (struct gdbarch *gdbarch, struct value *function, - struct regcache *regcache, CORE_ADDR bp_addr, int nargs, - struct value **args, CORE_ADDR sp, int struct_return, - CORE_ADDR struct_addr) -{ - int stack_alloc = 0, stack_offset = 0; - int wordsize = BINWORD; - int reg = E_ARG0_REGNUM; - int argument; - - /* First, make sure the stack is properly aligned. */ - sp = align_down (sp, wordsize); - - /* Now make sure there's space on the stack for the arguments.
