Yi Yang da4687923b cmd/compile: add rewrite rules for arithmetic operations ... Add the following common local transformations (t + x) - (t + y) == x - y (t + x) - (y + t) == x - y (x + t) - (y + t) == x - y (x + t) - (t + y) == x - y (x - t) + (t + y) == x + y (x - t) + (y + t) == x + y The compiler itself matches such patterns many times. This also aligns with other popular compilers.
