Sync to upstream/release/600 (#1076) ### What's Changed - Improve readability of unions and intersections by limiting the number of elements of those types that can be presented on a single line (gated under `FFlag::LuauToStringSimpleCompositeTypesSingleLine`) - Adds a new option to the compiler `--record-stats` to record and output compilation statistics - `if...then...else` expressions are now optimized into `AND/OR` form when possible. ### VM - Add a new `buffer` type to Luau based on the [buffer RFC](https://github.com/Roblox/luau/pull/739) and additional C API functions to work with it; this release does not include the library. - Internal C API to work with string buffers has been updated to align with Lua version more closely ### Native Codegen - Added support for new X64 instruction (rev) and new A64 instruction (bswap) in the assembler - Simplified the way numerical loop condition is translated to IR ### New Type Solver - Operator inference now handled by type families - Created a new system called `Type Paths` to explain why subtyping tests fail in order to improve the quality of error messages. - Systematic changes to implement Data Flow analysis in the new solver (`Breadcrumb` removed and replaced with `RefinementKey`) --- 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> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com>

Sync to upstream/release/616 (#1184) # What's Changed * Add a compiler hint to improve Luau memory allocation inlining ### New Type Solver * Added a system for recommending explicit type annotations to users in cases where we've inferred complex generic types with type families. * Marked string library functions as `@checked` for use in new non-strict mode. * Fixed a bug with new non-strict mode where we would incorrectly report arity mismatches when missing optional arguments. * Implement an occurs check for unifications that would produce self-recursive types. * Fix bug where overload resolution would fail when applied to non-overloaded functions. * Fix bug that caused the subtyping to report an error whenever a generic was instantiated in an invariant context. * Fix crash caused by `SetPropConstraint` not blocking properly. ### Native Code Generation * Implement optimization to eliminate dead stores * Optimize vector ops for X64 when the source is computed (thanks, @zeux!) * Use more efficient lowering for UNM_* (thanks, @zeux!) --- ### 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: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Vighnesh <vvijay@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/623 (#1236) # What's changed? ### New Type Solver - Unification of two fresh types no longer binds them together. - Replaced uses of raw `emplace` with `emplaceType` to catch cyclic bound types when they are created. - `SetIndexerConstraint` is blocked until the indexer result type is not blocked. - Fix a case where a blocked type got past the constraint solver. - Searching for free types should no longer traverse into `ClassType`s. - Fix a corner case that could result in the non-testable type `~{}`. - Fix incorrect flagging when `any` was a parameter of some checked function in nonstrict type checker. - `IterableConstraint` now consider tables without `__iter` to be iterables. ### Native Code Generation - Improve register type info lookup by program counter. - Generate type information for locals and upvalues --- ### 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: James McNellis <jmcnellis@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Vighnesh <vvijay@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/607 (#1131) # What's changed? * Fix up the `std::iterator_traits` definitions for some Luau data structures. * Replace some of the usages of `std::unordered_set` and `std::unordered_map` with Luau-provided data structures to increase performance and reduce overall number of heap allocations. * Update some of the documentation links in comments throughout the codebase to correctly point to the moved repository. * Expanded JSON encoder for AST to support singleton types. * Fixed a bug in `luau-analyze` where exceptions in the last module being checked during multithreaded analysis would not be rethrown. ### New type solver * Introduce a `refine` type family to handle deferred refinements during type inference, replacing the old `RefineConstraint`. * Continued work on the implementation of type states, fixing some known bugs/blockers. * Added support for variadic functions in new non-strict mode, enabling broader support for builtins and the Roblox API. ### 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: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Vighnesh <vvijay@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/607 (#1131) # What's changed? * Fix up the `std::iterator_traits` definitions for some Luau data structures. * Replace some of the usages of `std::unordered_set` and `std::unordered_map` with Luau-provided data structures to increase performance and reduce overall number of heap allocations. * Update some of the documentation links in comments throughout the codebase to correctly point to the moved repository. * Expanded JSON encoder for AST to support singleton types. * Fixed a bug in `luau-analyze` where exceptions in the last module being checked during multithreaded analysis would not be rethrown. ### New type solver * Introduce a `refine` type family to handle deferred refinements during type inference, replacing the old `RefineConstraint`. * Continued work on the implementation of type states, fixing some known bugs/blockers. * Added support for variadic functions in new non-strict mode, enabling broader support for builtins and the Roblox API. ### 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: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Vighnesh <vvijay@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/607 (#1131) # What's changed? * Fix up the `std::iterator_traits` definitions for some Luau data structures. * Replace some of the usages of `std::unordered_set` and `std::unordered_map` with Luau-provided data structures to increase performance and reduce overall number of heap allocations. * Update some of the documentation links in comments throughout the codebase to correctly point to the moved repository. * Expanded JSON encoder for AST to support singleton types. * Fixed a bug in `luau-analyze` where exceptions in the last module being checked during multithreaded analysis would not be rethrown. ### New type solver * Introduce a `refine` type family to handle deferred refinements during type inference, replacing the old `RefineConstraint`. * Continued work on the implementation of type states, fixing some known bugs/blockers. * Added support for variadic functions in new non-strict mode, enabling broader support for builtins and the Roblox API. ### 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: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Vighnesh <vvijay@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
