Sync to upstream/release/588 (#992) Type checker/autocomplete: * `Luau::autocomplete` no longer performs typechecking internally, make sure to run `Frontend::check` before performing autocomplete requests * Autocomplete string suggestions without "" are now only suggested inside the "" * Autocomplete suggestions now include `function (anonymous autofilled)` key with a full suggestion for the function expression (with arguments included) stored in `AutocompleteEntry::insertText` * `AutocompleteEntry::indexedWithSelf` is provided for function call suggestions made with `:` * Cyclic modules now see each other type exports as `any` to prevent memory use-after-free (similar to module return type) Runtime: * Updated inline/loop unroll cost model to better handle assignments (Fixes https://github.com/Roblox/luau/issues/978) * `math.noise` speed was improved by ~30% * `table.concat` speed was improved by ~5-7% * `tonumber` and `tostring` now have fastcall paths that execute ~1.5x and ~2.5x faster respectively (fixes #777) * Fixed crash in `luaL_typename` when index refers to a non-existing value * Fixed potential out of memory scenario when using `string.sub` or `string.char` in a loop * Fixed behavior of some fastcall builtins when called without arguments under -O2 to match original functions * Support for native code execution in VM is now enabled by default (note: native code still has to be generated explicitly) * `Codegen::compile` now accepts `CodeGen_OnlyNativeModules` flag. When set, only modules that have a `--!native` hot-comment at the top will be compiled to native code In our new typechecker: * Generic type packs are no longer considered to be variadic during unification * Timeout and cancellation now works in new solver * Fixed false positive errors around 'table' and 'function' type refinements * Table literals now use covariant unification rules. This is sound since literal has no type specified and has no aliases * Fixed issues with blocked types escaping the constraint solver * Fixed more places where error messages that should've been suppressed were still reported * Fixed errors when iterating over a top table type In our native code generation (jit): * 'DebugLuauAbortingChecks' flag is now supported on A64 * LOP_NEWCLOSURE has been translated to IR

Sync to upstream/release/577 (#934) Lots of things going on this week: * Fix a crash that could occur in the presence of a cyclic union. We shouldn't be creating cyclic unions, but we shouldn't be crashing when they arise either. * Minor cleanup of `luau_precall` * Internal change to make L->top handling slightly more uniform * Optimize SETGLOBAL & GETGLOBAL fallback C functions. * https://github.com/Roblox/luau/pull/929 * The syntax to the `luau-reduce` commandline tool has changed. It now accepts a script, a command to execute, and an error to search for. It no longer automatically passes the script to the command which makes it a lot more flexible. Also be warned that it edits the script it is passed **in place**. Do not point it at something that is not in source control! New solver * Switch to a greedier but more fallible algorithm for simplifying union and intersection types that are created as part of refinement calculation. This has much better and more predictable performance. * Fix a constraint cycle in recursive function calls. * Much improved inference of binary addition. Functions like `function add(x, y) return x + y end` can now be inferred without annotations. We also accurately typecheck calls to functions like this. * Many small bugfixes surrounding things like table indexers * Add support for indexers on class types. This was previously added to the old solver; we now add it to the new one for feature parity. JIT * https://github.com/Roblox/luau/pull/931 * Fuse key.value and key.tt loads for CEHCK_SLOT_MATCH in A64 * Implement remaining aliases of BFM for A64 * Implement new callinfo flag for A64 * Add instruction simplification for int->num->int conversion chains * Don't even load execdata for X64 calls * Treat opcode fallbacks the same as manually written fallbacks --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/610 (#1154) # What's changed? * Check interrupt handler inside the pattern match engine to eliminate potential for programs to hang during string library function execution. * Allow iteration over table properties to pass the old type solver. ### Native Code Generation * Use in-place memory operands for math library operations on x64. * Replace opaque bools with separate enum classes in IrDump to improve code maintainability. * Translate operations on inferred vectors to IR. * Enable support for debugging native-compiled functions in Roblox Studio. ### New Type Solver * Rework type inference for boolean and string literals to introduce bounded free types (bounded below by the singleton type, and above by the primitive type) and reworked primitive type constraint to decide which is the appropriate type for the literal. * Introduce `FunctionCheckConstraint` to handle bidirectional typechecking for function calls, pushing the expected parameter types from the function onto the arguments. * Introduce `union` and `intersect` type families to compute deferred simplified unions and intersections to be employed by the constraint generation logic in the new solver. * Implement support for expanding the domain of local types in `Unifier2`. * Rework type inference for iteration variables bound by for in loops to use local types. * Change constraint blocking logic to use a set to prevent accidental re-blocking. * Add logic to detect missing return statements in functions. ### 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: 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/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/577 (#934) Lots of things going on this week: * Fix a crash that could occur in the presence of a cyclic union. We shouldn't be creating cyclic unions, but we shouldn't be crashing when they arise either. * Minor cleanup of `luau_precall` * Internal change to make L->top handling slightly more uniform * Optimize SETGLOBAL & GETGLOBAL fallback C functions. * https://github.com/Roblox/luau/pull/929 * The syntax to the `luau-reduce` commandline tool has changed. It now accepts a script, a command to execute, and an error to search for. It no longer automatically passes the script to the command which makes it a lot more flexible. Also be warned that it edits the script it is passed **in place**. Do not point it at something that is not in source control! New solver * Switch to a greedier but more fallible algorithm for simplifying union and intersection types that are created as part of refinement calculation. This has much better and more predictable performance. * Fix a constraint cycle in recursive function calls. * Much improved inference of binary addition. Functions like `function add(x, y) return x + y end` can now be inferred without annotations. We also accurately typecheck calls to functions like this. * Many small bugfixes surrounding things like table indexers * Add support for indexers on class types. This was previously added to the old solver; we now add it to the new one for feature parity.

Sync to upstream/release/617 (#1204) # What's Changed * Fix a case where the stack wasn't completely cleaned up where `debug.info` errored when passed `"f"` option and a thread. * Fix a case of uninitialized field in `luaF_newproto`. ### New Type Solver * When a local is captured in a function, don't add a new entry to the `DfgScope::bindings` if the capture occurs within a loop. * Fix a poor performance characteristic during unification by not trying to simplify an intersection. * Fix a case of multiple constraints mutating the same blocked type causing incorrect inferences. * Fix a case of assertion failure when overload resolution encounters a return typepack mismatch. * When refining a property of the top `table` type, we no longer signal an unknown property error. * Fix a misuse of free types when trying to infer the type of a subscript expression. * Fix a case of assertion failure when trying to resolve an overload from `never`. ### Native Code Generation * Fix dead store optimization issues caused by partial stores. --- ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@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> --------- 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/614 (#1173) # What's changed? Add program argument passing to scripts run using the Luau REPL! You can now pass `--program-args` (or shorthand `-a`) to the REPL which will treat all remaining arguments as arguments to pass to executed scripts. These values can be accessed through variadic argument expansion. You can read these values like so: ``` local args = {...} -- gets you an array of all the arguments ``` For example if we run the following script like `luau test.lua -a test1 test2 test3`: ``` -- test.lua print(...) ``` you should get the output: ``` test1 test2 test3 ``` ### Native Code Generation * Improve A64 lowering for vector operations by using vector instructions * Fix lowering issue in IR value location tracking! - A developer reported a divergence between code run in the VM and Native Code Generation which we have now fixed ### New Type Solver * Apply substitution to type families, and emit new constraints to reduce those further * More progress on reducing comparison (`lt/le`)type families * Resolve two major sources of cyclic types in the new solver ### Miscellaneous * Turned internal compiler errors (ICE's) into warnings and errors ------- 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: Vyacheslav Egorov <vegorov@roblox.com> --------- 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: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

When set, only modules that have a `--!native` hot-comment at the top will be compiled to native code In our new typechecker: * Generic type packs are no longer considered to be variadic during unification * Timeout and cancellation now works in new solver * Fixed false positive errors around 'table' and 'function' type refinements * Table literals now use covariant unification rules. This is sound since literal has no type specified and has no aliases * Fixed issues with blocked types escaping the constraint solver * Fixed more places where error messages that should've been suppressed were still reported * Fixed errors when iterating over a top table type In our native code generation (jit): * 'DebugLuauAbortingChecks' flag is now supported on A64 * LOP_NEWCLOSURE has been translated to IR

Sync to upstream/release/577 (#934) Lots of things going on this week: * Fix a crash that could occur in the presence of a cyclic union. We shouldn't be creating cyclic unions, but we shouldn't be crashing when they arise either. * Minor cleanup of `luau_precall` * Internal change to make L->top handling slightly more uniform * Optimize SETGLOBAL & GETGLOBAL fallback C functions. * https://github.com/Roblox/luau/pull/929 * The syntax to the `luau-reduce` commandline tool has changed. It now accepts a script, a command to execute, and an error to search for. It no longer automatically passes the script to the command which makes it a lot more flexible. Also be warned that it edits the script it is passed **in place**. Do not point it at something that is not in source control! New solver * Switch to a greedier but more fallible algorithm for simplifying union and intersection types that are created as part of refinement calculation. This has much better and more predictable performance. * Fix a constraint cycle in recursive function calls. * Much improved inference of binary addition. Functions like `function add(x, y) return x + y end` can now be inferred without annotations. We also accurately typecheck calls to functions like this. * Many small bugfixes surrounding things like table indexers * Add support for indexers on class types. This was previously added to the old solver; we now add it to the new one for feature parity. JIT * https://github.com/Roblox/luau/pull/931 * Fuse key.value and key.tt loads for CEHCK_SLOT_MATCH in A64 * Implement remaining aliases of BFM for A64 * Implement new callinfo flag for A64 * Add instruction simplification for int->num->int conversion chains * Don't even load execdata for X64 calls * Treat opcode fallbacks the same as manually written fallbacks --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/591 (#1012) * Fix a use-after-free bug in the new type cloning algorithm * Tighten up the type of `coroutine.wrap`. It is now `<A..., R...>(f: (A...) -> R...) -> ((A...) -> R...)` * Break `.luaurc` out into a separate library target `Luau.Config`. This makes it easier for applications to reason about config files without also depending on the type inference engine. * Move typechecking limits into `FrontendOptions`. This allows embedders more finely-grained control over autocomplete's internal time limits. * Fix stability issue with debugger onprotectederror callback allowing break in non-yieldable contexts New solver: * Initial work toward [Local Type Inference](https://github.com/Roblox/luau/blob/0e1082108fd6fb3a32dfdf5f1766ea3fc1391328/rfcs/local-type-inference.md) * Introduce a new subtyping test. This will be much nicer than the old test because it is completely separate both from actual type inference and from error reporting. Native code generation: * Added function to compute iterated dominance frontier * Optimize barriers in SET_UPVALUE when tag is known * Cache lua_State::global in a register on A64 * Optimize constant stores in A64 lowering * Track table array size state to optimize array size checks * Add split tag/value store into a VM register * Check that spills can outlive the block only in specific conditions --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

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/622 (#1232) # What's changed? * Improved the actual message for the type errors for `cannot call non-function` when attempting to call a union of functions/callable tables. The error now correctly explains the issue is an inability to determine the return type of the call in this situation. * Resolve an issue where tables and metatables were not correctly being cloned during instantiation (fixes #1176). * Refactor `luaM_getnextgcopage` to `luaM_getnextpage` (generally removing `gco` prefix where appropriate). * Optimize `table.move` between tables for large ranges of elements. * Reformat a bunch of code automatically using `clang-format`. ### New Type Solver * Clean up minimally-used or unused constraints in the constraint solver (`InstantiationConstraint`, `SetOpConstraint`, `SingletonOrTopTypeConstraint`). * Add a builtin `singleton` type family to replace `SingletonOrTopTypeConstraint` when inferring refinements. * Fixed a crash involving type path reasoning by recording when type family reduction has taken place in the path. * Improved constraint ordering by blocking on unreduced types families that are not yet proven uninhabitable. * Improved the handling of `SetIndexerConstraints` for both better inference quality and to resolve crashes. * Fix a crash when normalizing cyclic unions of intersections. * Fix a crash when normalizing an intersection with the negation of `unknown`. * Fix a number of crashes caused by missing `follow` calls on `TypeId`s. * Changed type family reduction to correctly use a semantic notion of uninhabited types, rather than checking for `never` types specifically. * Refactor the `union` and `intersect` type families to be variadic. ### Native Code Generation * Improve translation for userdata key get/set and userdata/vector namecall. * Provide `[top level]` and `[anonymous]` as function names to `FunctionStats` as appropriate when no function name is available. * Disable unwind support on Android platforms since it is unsupported. * --- ### 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: Vighnesh Vijay <vvijay@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>
