NewABIConfig returns a new ABI configuration for an architecture with iRegsCount integer/pointer registers and fRegsCount floating point registers.

RegisterTypes returns a slice of the types of the registers corresponding to a slice of parameters.

ABIConfig captures the number of registers made available by the ABI rules for parameter passing and result returning.

ABIParamAssignment holds information about how a specific param or result will be passed: in registers (in which case 'Registers' is populated) or on the stack (in which case 'Offset' is set to a non-negative stack offset).

ABIParamResultInfo stores the results of processing a given function type to compute stack layout and register assignments.

RegAmounts holds a specified number of integer/float registers.

RegIndex stores the index into the set of machine registers used by the ABI on a specific architecture for parameter passing.
