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/562 (#828) * Fixed rare use-after-free in analysis during table unification A lot of work these past months went into two new Luau components: * A near full rewrite of the typechecker using a new deferred constraint resolution system * Native code generation for AoT/JiT compilation of VM bytecode into x64 (avx)/arm64 instructions Both of these components are far from finished and we don't provide documentation on building and using them at this point. However, curious community members expressed interest in learning about changes that go into these components each week, so we are now listing them here in the 'sync' pull request descriptions. --- New typechecker can be enabled by setting DebugLuauDeferredConstraintResolution flag to 'true'.

TableTests.nil_assign_doesnt_hit_no_indexer
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>

TypeInferModules.custom_require_global
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.

TypeSingletons.function_call_with_singletons_mismatch
TypeSingletons.indexing_on_union_of_string_singletons
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>
