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
