* Work toward affording parallel type checking * The interface to `LazyType` has changed: * `LazyType` now takes a second callback that is passed the `LazyType&` itself. This new callback is responsible for populating the field `TypeId LazyType::unwrapped`. Multithreaded implementations should acquire a lock in this callback. * Modules now retain their `humanReadableNames`. This reduces the number of cases where type checking has to call back to a `ModuleResolver`. * https://github.com/Roblox/luau/pull/902 * Add timing info to the Luau REPL compilation output We've also fixed some bugs and crashes in the new solver as we march toward readiness. * Thread ICEs (Internal Compiler Errors) back to the Frontend properly * Refinements are no longer applied to lvalues * More miscellaneous stability improvements Lots of activity in the new JIT engine: * Implement register spilling/restore for A64 * Correct Luau IR value restore location tracking * Fixed use-after-free in x86 register allocator spill restore * Use btz for bit tests * Finish branch assembly support for A64 * Codesize and performance improvements for A64 * The bit32 library has been implemented for arm and x64 --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
