Summary: The accumulator-based (HI/LO) multiplies and divides from earlier ISA's have been removed and replaced with GPR-based equivalents. For example: div $1, $2 mflo $3 is now: div $3, $1, $2 This patch disables the accumulator-based multiplies and divides for MIPS32r6/MIPS64r6 and uses the GPR-based equivalents instead. Renamed expandPseudoDiv to insertDivByZeroTrap to better describe the behaviour of the function. MipsDelaySlotFiller now invalidates the liveness information when moving instructions to the delay slot. Without this, divrem.ll will abort since %GP ends up used before it is defined.
