* to the register number)
*
* Each field in a register has the following definitions:
*
* S_rrrfff The shift count required to right-justify
* the field. This corresponds to the bit
* number of the right-most bit in the field.
* M_rrrfff The Mask required to isolate the field.
*
* Register diagrams included below as comments correspond to the
* MIPS32 and MIPS64 architecture specifications. Refer to other
* sources for register diagrams for older architectures.
