/* PA has a downward growing stack, which looks like this:
Offset
[ Variable args ]
SP = (4*(n+9)) arg word N
...
SP-52 arg word 4
[ Fixed args ]
SP-48 arg word 3
SP-44 arg word 2
SP-40 arg word 1
SP-36 arg word 0
[ Frame marker ]
...
SP-20 RP
SP-4 previous SP
The first four argument words on the stack are reserved for use by
the callee. Instead, the general and floating registers replace
the first four argument slots. Non FP arguments are passed solely
in the general registers. FP arguments are passed in both general
and floating registers when using libffi.
Non-FP 32-bit args are passed in gr26, gr25, gr24 and gr23.
Non-FP 64-bit args are passed in register pairs, starting
on an odd numbered register (i.e. r25+r26 and r23+r24).
FP 32-bit arguments are passed in fr4L, fr5L, fr6L and fr7L.
FP 64-bit arguments are passed in fr5 and fr7.
The registers are allocated in the same manner as stack slots.
This allows the callee to save its arguments on the stack if
necessary:
arg word 3 -> gr23 or fr7L
arg word 2 -> gr24 or fr6L or fr7R
arg word 1 -> gr25 or fr5L
arg word 0 -> gr26 or fr4L or fr5R
Note that fr4R and fr6R are never used for arguments (i.e.,
doubles are not passed in fr4 or fr6).
The rest of the arguments are passed on the stack starting at SP-52,
but 64-bit arguments need to be aligned to an 8-byte boundary
This means we can have holes either in the register allocation,
or in the stack. */
/* ffi_prep_args is called by the assembly routine once stack space
has been allocated for the function's arguments
The following code will put everything into the stack frame
(which was allocated by the asm routine), and on return
the asm routine will load the arguments that should be
passed by register into the appropriate registers
NOTE: We load floating point args in this function... that means we
assume gcc will not mess with fp regs in here. */
