For floats: When const >= function.max, comparisons of function > const always yield FALSE. When const < function.min, comparisons of function > const always yield TRUE. When const > function.max, comparisons of function < const always yield TRUE. When const <= function.min, comparisons of function < const always yield FALSE. For integers: When min = -1, cond(function > -1) is the same as cond(!~function). When min = -1, cond(function < 0) is the same as cond(~function). To implement the above, we got rid of the cond(x < 0) -> cond(x & 0x80000000) optimization, which has caused more trouble than it has solved for just 1 byte gain. When min = 0, cond(function > 0) is the same as cond(function). When min = 0, cond(function < 1) is the same as cond(!function). Similar expressions can be obtained for max in [-1, 0], but it's not worth it, as there are no functions with -1 as maximum, and the ones with max=0 also have min=0 (always return 0). |
