VIPS Assembly Language Design a. P&H(2.21). Provide a minimal set of MIPS instructions that may be used to implement the following pseudoinstruction [We've talked about pseudoinstructions before with mov. Effectively they are assembly instructions that aren't actually in the ISA of hardware, so the assembler has to translate them into another machine instruction or series of machine instructions.]: not $t1,$t2 / / bit-wise invert b. You are tasked with adding a new pseudoinstruction that takes the two's complement of a register's value: ttc \$t1 / / takes the two's complement of t1 Give a minimal implementation. Should this instruction produce any exceptions (i.e., can it produce any errors)? If so, what are they and does your implementation handle them? c. Why does MIPS not have add label_dst, label_src1, label_src2, instructions in its ISA (there are at least two reasons for this)? [Read this instruction's function as M [label_dst] =M[ label_src1] +M [label_src2].] Provide a concrete technical justification-you should have ideas both from lab and lecture
