Basic Block Optimizations

Common Sub-Expression Elimination a = (x+y)+z; b = x+y; t = x+y; a = t+z; b = t; Constant Propagation x = 5; b = x+y; b = 5+y; Algebraic Identities a = x * 1; a = x;. Copy Propagation a = x+y; b = a; c = b+z; a = x+y; b = a; c = a+z; Dead Code Elimination a = x+y; b = a; c = a+z;
