a != -1 is now optimized to ~a in conditions. a == 1, a != 1, etc. are all optimized. a||b -> a|b is done. a^0, a^-1 are optimized. a&&b is transformed to !(!a|!b), but not yet into a&b when possible.
The output module adds parentheses where necessary, depending on the evaluation order in the tree. Or that's the idea. Prone to bugs, let's see how it bodes.
- Fix a bunch of bugs found during the debut of the LSL calculator.
- Add infrastructure for functions to be able to produce a result or not depending on arguments. Fixes the llBase64ToInteger/llXorBase64/llXorBase64StringsCorrect cases where they are not deterministic, and allows for the addition of some extra functions whose value can be determined in some cases (e.g. llDetectedType(-1) is always 0). Added several such functions in a new module.
- Add the constant folding option to the help and the default options.
