Sync to upstream/release/563 (#833) * Fix a bug where reading a property from an unsealed table caused inference to improperly infer the existence of that property. * Fix #827 We have also made a lot of progress on the new solver and the JIT. Both projects are still in the process of being built out. Neither are ready for general use yet. We are mostly working to tighten up how the new solver handles refinements and updates to unsealed tables to bring it up to the same level as the old solver. --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@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/565 (#845) We've made a few small changes to reduce the amount of stack we use when typechecking nested method calls (eg `foo:bar():baz():quux()`). We've also fixed a small bytecode compiler issue that caused us to emit redundant jump instructions in code that conditionally uses `break` or `continue`. On the new solver, we've switched to a new, better way to handle augmentations to unsealed tables. We've also made some substantial improvements to type inference and error reporting on function calls. These things should both be on par with the old solver now. The main improvements to the native code generator have been elimination of some redundant type tag checks. Also, we are starting to inline particular fastcalls directly to IR. --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/568 (#865) * A small subset of control-flow refinements have been added to recognize type options that are unreachable after a conditional/unconditional code block. (Fixes https://github.com/Roblox/luau/issues/356). Some examples: ```lua local function f(x: string?) if not x then return end -- x is 'string' here end ``` Throwing calls like `error` or `assert(false)` instead of 'return' are also recognized. Existing complex refinements like type/typeof and tagged union checks are expected to work, among others. To enable this feature, `LuauTinyControlFlowAnalysis` exclusion has to be removed from `ExperimentalFlags.h`. If will become enabled unconditionally in the near future. * Linter has been integrated into the typechecker analysis so that type-aware lint warnings can work in any mode `Frontend::lint` methods were deprecated, `Frontend::check` has to be used instead with `runLintChecks` option set. Resulting lint warning are located inside `CheckResult`. * Fixed large performance drop and increased memory consumption when array is filled at an offset (Fixes https://github.com/Roblox/luau/issues/590) * Part of [Type error suppression RFC](https://github.com/Roblox/luau/blob/master/rfcs/type-error-suppression.md) was implemented making subtyping checks with `any` type transitive. --- In our work on the new type-solver: * `--!nocheck` mode no longer reports type errors * New solver will not be used for `--!nonstrict` modules until all issues with strict mode typechecking are fixed * Added control-flow aware type refinements mentioned earlier In native code generation: * `LOP_NAMECALL` has been translated to IR * `type` and `typeof` builtin fastcalls have been translated to IR/assembly * Additional steps were taken towards arm64 support

Sync to upstream/release/570 (#885) Once again, all of our changes this week are for new type solver and the JIT. In the new type solver, we fixed cyclic type alias handling and multiple stability issues. In the JIT, our main progress was for arm64, where, after lowering 36% of instructions, we start seeing first Luau functions executing natively. For x64, we performed code cleanup and refactoring to allow for future optimizations.

Sync to upstream/release/568 (#865) * A small subset of control-flow refinements have been added to recognize type options that are unreachable after a conditional/unconditional code block. (Fixes https://github.com/Roblox/luau/issues/356). Some examples: ```lua local function f(x: string?) if not x then return end -- x is 'string' here end ``` Throwing calls like `error` or `assert(false)` instead of 'return' are also recognized. Existing complex refinements like type/typeof and tagged union checks are expected to work, among others.

Sync to upstream/release/570 (#885) Once again, all of our changes this week are for new type solver and the JIT. In the new type solver, we fixed cyclic type alias handling and multiple stability issues. In the JIT, our main progress was for arm64, where, after lowering 36% of instructions, we start seeing first Luau functions executing natively. For x64, we performed code cleanup and refactoring to allow for future optimizations.

Sync to upstream/release/565 (#845) We've made a few small changes to reduce the amount of stack we use when typechecking nested method calls (eg `foo:bar():baz():quux()`). We've also fixed a small bytecode compiler issue that caused us to emit redundant jump instructions in code that conditionally uses `break` or `continue`. On the new solver, we've switched to a new, better way to handle augmentations to unsealed tables. We've also made some substantial improvements to type inference and error reporting on function calls. These things should both be on par with the old solver now. The main improvements to the native code generator have been elimination of some redundant type tag checks. Also, we are starting to inline particular fastcalls directly to IR. --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/567 (#860) * Fix #817 * Fix #850 * Optimize math.floor/ceil/round with SSE4.1 * Results in a ~7-9% speedup on the math-cordic benchmark. * Optimized table.sort. * table.sort is now ~4.1x faster (when not using a predicate) and ~2.1x faster when using a simple predicate. Performance may improve further in the future. * Reorganize the memory ownership of builtin type definitions. * This is a small initial step toward affording parallel typechecking. The new type solver is coming along nicely. We are working on fixing crashes and bugs. A few major changes to native codegen landed this week: * Fixed lowering of Luau IR mod instruction when first argument is a constant * Added VM register data-flow/capture analysis * Fixed issues with optimizations in unreachable blocks --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

In the new type solver, we fixed cyclic type alias handling and multiple stability issues. In the JIT, our main progress was for arm64, where, after lowering 36% of instructions, we start seeing first Luau functions executing natively. For x64, we performed code cleanup and refactoring to allow for future optimizations.

Note that this change can be observable if `getfenv/setfenv` is used to substitute a builtin, especially if arity is different. Fastcall heavy tests show a 1-2% improvement. * Luau can now be built with clang-cl (Fixes https://github.com/Roblox/luau/issues/736) We also made many improvements to our experimental components. For our new type solver: * Overhauled data flow analysis system, fixed issues with 'repeat' loops, global variables and type annotations * Type refinements now work on generic table indexing with a string literal * Type refinements will properly track potentially 'nil' values (like t[x] for a missing key) and their further refinements * Internal top table type is now isomorphic to `{}` which fixes issues when `typeof(v) == 'table'` type refinement is handled * References to non-existent types in type annotations no longer resolve to 'error' type like in old solver * Improved handling of class unions in property access expressions * Fixed default type packs * Unsealed tables can now have metatables * Restored expected types for function arguments And for native code generation: * Added min and max IR instructions mapping to vminsd/vmaxsd on x64 * We now speculatively extract direct execution fast-paths based on expected types of expressions which provides better optimization opportunities inside a single basic block * Translated existing math fastcalls to IR form to improve tag guard removal and constant propagation

Sync to upstream/release/570 (#885) Once again, all of our changes this week are for new type solver and the JIT. In the new type solver, we fixed cyclic type alias handling and multiple stability issues. In the JIT, our main progress was for arm64, where, after lowering 36% of instructions, we start seeing first Luau functions executing natively. For x64, we performed code cleanup and refactoring to allow for future optimizations.

Sync to upstream/release/565 (#845) We've made a few small changes to reduce the amount of stack we use when typechecking nested method calls (eg `foo:bar():baz():quux()`). We've also fixed a small bytecode compiler issue that caused us to emit redundant jump instructions in code that conditionally uses `break` or `continue`. On the new solver, we've switched to a new, better way to handle augmentations to unsealed tables. We've also made some substantial improvements to type inference and error reporting on function calls. These things should both be on par with the old solver now. The main improvements to the native code generator have been elimination of some redundant type tag checks.

Sync to upstream/release/566 (#853) * Fixed incorrect lexeme generated for string parts in the middle of an interpolated string (Fixes https://github.com/Roblox/luau/issues/744) * DeprecatedApi lint can report some issues without type inference information * Fixed performance of autocomplete requests when suggestions have large intersection types (Solves https://github.com/Roblox/luau/discussions/847) * Marked `table.getn`/`foreach`/`foreachi` as deprecated ([RFC: Deprecate table.getn/foreach/foreachi](https://github.com/Roblox/luau/blob/master/rfcs/deprecate-table-getn-foreach.md)) * With -O2 optimization level, we now optimize builtin calls based on known argument/return count. Note that this change can be observable if `getfenv/setfenv` is used to substitute a builtin, especially if arity is different. Fastcall heavy tests show a 1-2% improvement. * Luau can now be built with clang-cl (Fixes https://github.com/Roblox/luau/issues/736) We also made many improvements to our experimental components. For our new type solver: * Overhauled data flow analysis system, fixed issues with 'repeat' loops, global variables and type annotations * Type refinements now work on generic table indexing with a string literal * Type refinements will properly track potentially 'nil' values (like t[x] for a missing key) and their further refinements * Internal top table type is now isomorphic to `{}` which fixes issues when `typeof(v) == 'table'` type refinement is handled * References to non-existent types in type annotations no longer resolve to 'error' type like in old solver * Improved handling of class unions in property access expressions * Fixed default type packs * Unsealed tables can now have metatables * Restored expected types for function arguments And for native code generation: * Added min and max IR instructions mapping to vminsd/vmaxsd on x64 * We now speculatively extract direct execution fast-paths based on expected types of expressions which provides better optimization opportunities inside a single basic block * Translated existing math fastcalls to IR form to improve tag guard removal and constant propagation

Sync to upstream/release/570 (#885) Once again, all of our changes this week are for new type solver and the JIT. In the new type solver, we fixed cyclic type alias handling and multiple stability issues. In the JIT, our main progress was for arm64, where, after lowering 36% of instructions, we start seeing first Luau functions executing natively. For x64, we performed code cleanup and refactoring to allow for future optimizations.

Sync to upstream/release/565 (#845) We've made a few small changes to reduce the amount of stack we use when typechecking nested method calls (eg `foo:bar():baz():quux()`). We've also fixed a small bytecode compiler issue that caused us to emit redundant jump instructions in code that conditionally uses `break` or `continue`. On the new solver, we've switched to a new, better way to handle augmentations to unsealed tables. We've also made some substantial improvements to type inference and error reporting on function calls. These things should both be on par with the old solver now. The main improvements to the native code generator have been elimination of some redundant type tag checks. Also, we are starting to inline particular fastcalls directly to IR. --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/570 (#885) Once again, all of our changes this week are for new type solver and the JIT. In the new type solver, we fixed cyclic type alias handling and multiple stability issues. In the JIT, our main progress was for arm64, where, after lowering 36% of instructions, we start seeing first Luau functions executing natively. For x64, we performed code cleanup and refactoring to allow for future optimizations.

Sync to upstream/release/567 (#860) * Fix #817 * Fix #850 * Optimize math.floor/ceil/round with SSE4.1 * Results in a ~7-9% speedup on the math-cordic benchmark. * Optimized table.sort. * table.sort is now ~4.1x faster (when not using a predicate) and ~2.1x faster when using a simple predicate. Performance may improve further in the future. * Reorganize the memory ownership of builtin type definitions. * This is a small initial step toward affording parallel typechecking. The new type solver is coming along nicely. We are working on fixing crashes and bugs. A few major changes to native codegen landed this week: * Fixed lowering of Luau IR mod instruction when first argument is a constant * Added VM register data-flow/capture analysis * Fixed issues with optimizations in unreachable blocks --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/568 (#865) * A small subset of control-flow refinements have been added to recognize type options that are unreachable after a conditional/unconditional code block.
