AstQuery.last_argument_function_call_type
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/597 (#1054) # New Type Solver - Implement bidirectional type inference for higher order functions so that we can provide a more precise type improving the autocomplete's human factors. - We seal all tables, so we changed the stringification to make it a little lighter on users. - Fixed a case of array-out-of-bound access. - Type families no longer depends on `TxnLog` and `Unifier`. - Type refinements now waits until the free types are sufficiently solved. # Native Code Generation - Remove cached slot lookup for `executeSETTABLEKS` function because it is a fallback in the event of a cache miss, making the cached slot lookup redundant. - Optimized repeated array lookups, e.g. `a[3]` in `a[3] = a[3] / 2` is done once. # Misc - On some platforms, it is necessary to use `gmtime_s` with the arguments reversed to get the current time. You can now define `DOCTEST_CONFIG_USE_GMTIME_S` to build and run unit tests on those platforms. --------- 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>

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/569 (#878) All of our changes this week have been focused on the new type solver and the JIT. As we march toward feature parity with the old solver, we've tightened up a bunch of lingering issues with overload resolution, unsealed tables, and type normalization. We've also fixed a bunch of crashes and assertion failures in the new solver. On the JIT front, we've started work on an A64 backend, improved the IR analysis in a bunch of cases, and implemented assembly generation for the builtin functions `type()` and `typeof()`. --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.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>

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>

TypeInfer.recursive_function_that_invokes_itself_with_a_refinement_of_its_parameter
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

TypeInferFunctions.dont_give_other_overloads_message_if_only_one_argument_matching_overload_exists
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/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>

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/630 (#1295) ### What's new * A bug in exception handling in GCC(11/12/13) on MacOS prevents our test suite from running. * Parser now supports leading `|` or `&` when declaring `Union` and `Intersection` types (#1286) * We now support parsing of attributes on functions as described in the [rfc](https://github.com/luau-lang/rfcs/pull/30) * With this change, expressions such as `local x = @native function(x) return x+1 end` and `f(@native function(x) return x+1 end)` are now valid. * Added support for `@native` attribute - we can now force native compilation of individual functions if the `@native` attribute is specified before the `function` keyword (works for lambdas too). ### New Solver * Many fixes in the new solver for crashes and instability * Refinements now use simplification and not normalization in a specific case of two tables * Assume that compound assignments do not change the type of the left-side operand * Fix error that prevented Class Methods from being overloaded ### VM * Updated description of Garbage Collector invariant --- ### 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: 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>

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/564 (#841) This week we only have updates to new type solver and JIT. Both projects are still in the process of being built out. Neither are ready for general use yet. In the new solver, we fixed issues with recursive type aliases. Duplicated type parameters are once again reported, exported types are being recorder and function argument names are placed inside function types. We also made improvements to restore parts of bidirectional type tracking. On native code generation side, namecall instruction lowering was fixed, we fixed inconsistencies in IR command definitions and added utility function to help with constant folding.

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/611 (#1160) # What's changed? ### Native Code Generation * Fixed an UAF relating to reusing a hash key after a weak table has undergone some GC. * Fixed a bounds check on arm64 to allow access to the last byte of a buffer. ### New Type Solver * Type states now preserves error-suppression, i.e. `local x: any = 5` and `x.foo` does not error. * Made error-suppression logic in subtyping more accurate. * Subtyping now knows how to reduce type families. * Fixed function call overload resolution so that the return type resolves to the correct overload. * Fixed a case where we attempted to reduce irreducible type families a few too many times, leading to duplicate errors. * Type checker needs to type check annotations in function signatures to be able to report errors relating to those annotations. * Fixed an UAF from a pointer to stack-allocated data in Subtyping's `explainReasonings`. ### Nonstrict Type Checker * Fixed a crash when calling a checked function of the form `math.abs` with an incorrect argument type. * Fixed a crash when calling a checked function with a number of arguments that did not exactly match the number of parameters required. --- ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@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>

TypeStatesTest.typestates_preserve_error_suppression_properties
Sync to upstream/release/599 (#1069) ## What's Changed - Improve POSIX compliance in `CLI/FileUtils.cpp` by @SamuraiCrow #1064 - `AstStat*::hasEnd` is deprecated; use `AstStatBlock::hasEnd` instead - Added a lint for common misuses of the `#` operator - Luau now issues deprecated diagnostics for some uses of `getfenv` and `setfenv` - Fixed a case where we included a trailing space in some error stringifications ### Compiler - Do not do further analysis in O2 on self functions - Improve detection of invalid repeat..until expressions vs continue ### New Type Solver - We now cache subtype test results to improve performance - Improved operator inference mechanics (aka type families) - Further work towards type states - Work towards [new non-strict mode](https://github.com/Roblox/luau/blob/master/rfcs/new-nonstrict.md) continues ### Native Codegen - Instruction last use locations should follow the order in which blocks are lowered - Add a bonus assertion to IrLoweringA64::tempAddr --- 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: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com>
