+ 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. */
