# What's changed? * Fixed a bug in type cloning by maintaining persistent types. * We now parse imprecise integer literals to report the imprecision as a warning to developers. * Add a compiler flag to specify the name of the statistics output file. ### New type solver * Renamed `ConstraintGraphBuilder` to `ConstraintGenerator` * LValues now take into account the type being assigned during constraint generation. * Normalization performance has been improved by 33% by replacing the an internal usage of `std::unordered_set` with `DenseHashMap`. * Normalization now has a helper to identify types that are equivalent to `unknown`, which is being used to fix some bugs in subtyping. * Uses of the old unifier in the new type solver have been eliminated. * Improved error explanations for subtyping errors in `TypeChecker2`. ### Native code generation * Expanded some of the statistics recorded during compilation to include the number of instructions and blocks. * Introduce instruction and block count limiters for controlling what bytecode is translated into native code. * Implement code generation for byteswap instruction. ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com>
