/*
For mac, the first 8 integral and the first 13 f.p. parameters arrive
in a separate chunk of data that has been loaded from the registers. The
args pointer has been set to the start of the parameters BEYOND the ones
arriving in registers
*/
/* Under the Mac OS X PowerPC ABI, the first 8 integer and 13 floating point
* parameters are delivered in registers and are not on the stack, although
* stack space is allocated for them. The integer parameters are delivered
* in GPRs r3 through r10. The first 8 words of the parameter area on the
* stack shadow these registers. A word will either be in a register or on
* the stack, but not in both. Although the first floating point parameters
* are passed in floating point registers, GPR space and stack space is
* reserved for them as well.
*
* SharedStub has passed pointers to the parameter section of the stack
* and saved copies of the GPRs and FPRs used for parameter passing. We
* don't care about the first parameter (which is delivered here as the self
* pointer), so SharedStub pointed us past that. argsGPR thus points to GPR
* r4 (corresponding to the first argument after the self pointer) and
* argsStack points to the parameter section of the caller's stack frame
* reserved for the same argument. This way, it is possible to reference
* either argsGPR or argsStack with the same index.
*
* Contrary to the assumption made by the previous implementation, the
* Mac OS X PowerPC ABI doesn't impose any special alignment restrictions on
* parameter sections of stacks. Values that are 64 bits wide appear on the
* stack without any special padding.
*
* See also xptcstubs_asm_ppc_darwin.s.m4:_SharedStub.
