Notes

The expression should result in a 32-bit integer value in the range -2 ³¹ to 2 ³² - 1. There are four possible machine instruction representations of this macro instruction, depending on the value of the expression:

ori rC, $0, IMM32	if IMM32 is in the range 0 to 216 - 1 (i.e. from `0000_0000h` to `0000_FFFFh)`
addiu rC, $0, IMM32	if IMM32 is in the range -215 to -1 (i.e. from `FFFF_8000h` to `FFFF_FFFFh`)
lui rC, @MSH(IMM32)	if IMM32 is a multiple of 216 (i.e. of the form `xxxx_0000h`)
lui $at, @MSH(IMM32) ori rC, $at, @LSH(IMM32)	for all other values of IMM32

Relocatable expressions are not allowed.
