Review the following MIPS assembly code. a. Write code that the assembler will assemble after macro expansion of the code. [5pts] b. Show the symbol table for this code using relative index of instruction starting at 1. [5pts] .macro macl ($argl) add $arg1, $argl, $argl addi arg1, $arg1, -1 .end_macro .macro mac2 ($argl, $arg2) macl ($arg2) sub $arg1, $argl, $arg2 .end_macro .text L1: addi $t1, $zero, 10 addi $t2, $zero, 5 L2: macl ($t2) mac2 ($t1, $t2) beq $t1, $t2, L4 L3: mac2 ($t1, $t2) L4: macl ($t2) L5: bne $t2, $t1, L2
