ISA may support different flavors of conditional branch instructions such as BZ (branch on Zero), BN (branch on negative), and BEQ (branch on equal). Figure out the predicate expressions in an “if” statement that may be best served by these different flavors of conditional branch instructions. Give examples of such predicates in “if” statement, and how you will compile them using these different flavors of branch instructions.
What will be an ideal response?
BZ: if (a == 0)
BEQ: if (a == b)
BN: if (a < 0) or if (a < b) which becomes if (a-b < 0)
BP: if (a > 0) or if (a>b) which becomes if(a-b > 0)
