This question describes two new instructions we might consider adding to the Y86-64 processor. Give the actions that a SEQ-style Y86-64 implementation would take in each stage to execute the instruction. For each instruction, fill out the table below, with a row for Fetch, Decode, Execute, Memory, Write Back, and PC update. Use signal names like valA, and R[...] and M[...] to represent access to the register file and memory respectively. The leave instruction is used to clean up a stack frame when a frame pointer is in use. It first copies the frame pointer %rbp into the stack pointer %rsp and then it pops the top entry of the stack into %rbp. In other words, it is equivalent to the two-instruction sequence: movq %rbp, %rsp popq %rbp The indirect jump instruction jmp *D(rA) jumps to a code address stored at the location D + rA, like the x86-64 instruction used to implement a jump table.
