Q. 30 Consider a new instruction named branch-on-bit-set (mnemonic bbs). The instruction “bbs reg, pos, labbel” jumps to label if bit in position pos of register operand reg is one. a register is 32 bits wide and the bits are numbered 0 to 31, bit in position 0 being the least significant. Consider the following emulation of this instruction on a processor that does not have bbs implemented.
temp←reg&mask
Branch to label if temp is non-zero The variable temp is a temporary register. For correct emulation the variable mask must be generated by
