From 004d88ff2b05758947ea1d1f4919e7bb2192b880 Mon Sep 17 00:00:00 2001 From: ariel Date: Fri, 6 Mar 2026 15:35:49 -0800 Subject: [PATCH 01/61] Sync to upstream/release/711 (#2280) Hi there, folks! We're back with another weekly Luau release! # Language * Adds the `const` keyword for defining constant bindings that are statically forbidden to be reassigned to. This implements [luau-lang/rfcs#166](https://github.com/luau-lang/rfcs/pull/166). * Adds a collection of new math constants to Luau's `math` library per [luau-lang/rfcs#169](https://github.com/luau-lang/rfcs/pull/169). # Analysis * Fixes a class of bugs where Luau would not retain reasonable upper or lower bounds on free types, resulting in types snapping to `never` or `unknown` despite having bounds. ```luau --!strict -- `lines` will be inferred to be of `{ string }` now, and prior -- was local lines = {} table.insert(lines, table.concat({}, "")) print(table.concat(lines, "\n")) ``` ```luau --!strict -- `buttons` will be inferred to be of type `{ { a: number } }` local buttons = {} table.insert(buttons, { a = 1 }) table.insert(buttons, { a = 2, b = true }) table.insert(buttons, { a = 3 }) ``` * Disables the type error from `string.format` when called with a dynamically-determined format string (i.e. a non-literal string argument with the type `string`) in response to user feedback about it being too noisy. * Resolves an ICE that could occur when type checking curried generic functions. Fixes #2061! * Fixes false positive type errors from doing equality or inequality against `nil` when indexing from a table * In #2256, adds a state parameter to the `useratom` callback for consistency with other callbacks. # Compiler - Improves the compiler's type inference for vector component access, numerical for loops, function return types and singleton type annotations, fixing #2244 #2235 and #2255. # Native Code Generation - Fixes a bug where some operations on x86_64 would produce integers that would take up more than 32-bits when a 32-bit integer is expected. We resolve these issues by properly truncating to 32-bits in these situations. - Improves dead store elimination for conditional jumps and fastcalls arguments, improving overall native codegen performance by about 2% on average in benchmarks, with some benchmarks as high as 25%. --------- Co-authored-by: Vyacheslav Egorov --- Analysis/include/Luau/ConstraintGenerator.h | 11 + Analysis/include/Luau/Frontend.h | 4 +- Analysis/include/Luau/Generalization.h | 11 +- Analysis/include/Luau/InferPolarity.h | 19 -

This helps to avoid pathalogical misoptimizations that could result in the compiling bytecode growing very large. * fix constant placement into the CHECK_BUFFER_LEN 'double source' argument --------- Co-authored-by: Vyacheslav Egorov Co-authored-by: Ariel Weiss --- Analysis/include/Luau/ExpectedTypeVisitor.h | 12 + Analysis/include/Luau/Generalization.h | 10 +- Analysis/include/Luau/TypeChecker2.h | 4 +- Analysis/include/Luau/TypeFunction.h | 13 +- Analysis/include/Luau/Unifier2.h | 4 +- Analysis/src/AstQuery.cpp | 139 +-- Analysis/src/BuiltinDefinitions.cpp | 36 +- Analysis/src/BuiltinTypeFunctions.cpp | 29 +- Analysis/src/ConstraintGenerator.cpp | 40 +- Analysis/src/ConstraintSolver.cpp | 229 +++-- Analysis/src/DataFlowGraph.cpp | 21 +- Analysis/src/EmbeddedBuiltinDefinitions.cpp | 31 +- Analysis/src/Error.cpp | 42 +- Analysis/src/ExpectedTypeVisitor.cpp | 35 +- Analysis/src/FragmentAutocomplete.cpp | 189 +--- Analysis/src/Frontend.cpp | 36 +- Analysis/src/Generalization.cpp | 213 +---- Analysis/src/Linter.cpp | 66 +- Analysis/src/Module.cpp | 12 +- Analysis/src/Normalize.cpp | 2 +- Analysis/src/StructuralTypeEquality.cpp | 19 +- Analysis/src/Substitution.cpp | 27 +- Analysis/src/Subtyping.cpp | 43 +- Analysis/src/ToDot.cpp | 22 +- Analysis/src/ToString.cpp | 452 +++------ Analysis/src/Type.cpp | 31 +- Analysis/src/TypeChecker2.cpp | 6 +- Analysis/src/TypeFunction.cpp | 28 +- Analysis/src/TypeFunctionRuntime.cpp | 69 +- Analysis/src/TypeFunctionRuntimeBuilder.cpp | 6 +- Analysis/src/TypePath.cpp | 19 +- Analysis/src/TypeUtils.cpp | 27 +- Analysis/src/Unifier.cpp | 11 +- Analysis/src/Unifier2.cpp | 62 +- Ast/include/Luau/Ast.h | 10 +- Ast/src/Parser.cpp | 41 +- CodeGen/src/BytecodeAnalysis.cpp | 13 +- CodeGen/src/EmitCommonX64.h | 2 +- CodeGen/src/IrLoweringA64.cpp | 5 +- CodeGen/src/IrLoweringX64.cpp | 54 +- CodeGen/src/IrRegAllocA64.cpp | 63 +- CodeGen/src/IrRegAllocA64.h | 3 +- CodeGen/src/IrRegAllocX64.cpp | 8 +- CodeGen/src/IrTranslateBuiltins.cpp | 64 +- CodeGen/src/IrTranslation.cpp | 40 +- CodeGen/src/IrUtils.cpp | 3 +- CodeGen/src/OptimizeConstProp.cpp | 12 +- Compiler/src/BytecodeBuilder.cpp | 38 +- Compiler/src/Compiler.cpp | 67 +- Compiler/src/ConstantFolding.cpp | 167 ++-- Compiler/src/CostModel.cpp | 47 +- VM/include/lua.h | 6 +- fuzz/linter.cpp | 2 - fuzz/proto.cpp | 1 - tests/AstQuery.test.cpp | 11 +- tests/Autocomplete.test.cpp | 64 ++ tests/Compiler.test.cpp | 86 +- tests/Conformance.test.cpp | 6 - tests/Error.test.cpp | 20 +- tests/Fixture.cpp | 2 + tests/Fixture.h | 7 + tests/FragmentAutocomplete.test.cpp | 198 +++- tests/Frontend.test.cpp | 6 +- tests/Generalization.test.cpp | 35 +- tests/IrBuilder.test.cpp | 2 - tests/IrLowering.test.cpp | 30 +- tests/Linter.test.cpp | 3 +- tests/Normalize.test.cpp | 18 +- tests/Parser.test.cpp | 37 +- tests/ToDot.test.cpp | 6 +- tests/ToString.test.cpp | 35 +- tests/TypeFunction.test.cpp | 50 +- tests/TypeFunction.user.test.cpp | 39 +- tests/TypeInfer.aliases.test.cpp | 11 +- tests/TypeInfer.anyerror.test.cpp | 1 - tests/TypeInfer.builtins.test.cpp | 118 +-- tests/TypeInfer.cfa.test.cpp | 19 +- tests/TypeInfer.classes.test.cpp | 121 +-- tests/TypeInfer.functions.test.cpp | 390 ++++---- tests/TypeInfer.generics.test.cpp | 100 +- tests/TypeInfer.intersectionTypes.test.cpp | 986 ++++++-------------- tests/TypeInfer.loops.test.cpp | 6 +- tests/TypeInfer.modules.test.cpp | 51 +- tests/TypeInfer.operators.test.cpp | 6 +- tests/TypeInfer.primitives.test.cpp | 12 +- tests/TypeInfer.provisional.test.cpp | 77 +- tests/TypeInfer.refinements.test.cpp | 16 +- tests/TypeInfer.singletons.test.cpp | 67 +- tests/TypeInfer.tables.test.cpp | 515 +++++----- tests/TypeInfer.test.cpp | 20 +- tests/TypeInfer.typeInstantiations.test.cpp | 24 +- tests/TypeInfer.typePacks.test.cpp | 57 +- tests/TypeInfer.typestates.test.cpp | 6 +- tests/TypeInfer.unionTypes.test.cpp | 188 ++-- tests/TypePath.test.cpp | 2 - 95 files changed, 2381 insertions(+), 3698 deletions(-) diff --git a/Analysis/include/Luau/ExpectedTypeVisitor.h b/Analysis/include/Luau/ExpectedTypeVisitor.h index 4b195359..19ce46ca 100644 --- a/Analysis/include/Luau/ExpectedTypeVisitor.h +++ b/Analysis/include/Luau/ExpectedTypeVisitor.h @@ -21,6 +21,16 @@ struct ExpectedTypeVisitor : public AstVisitor NotNull rootScope ); + explicit ExpectedTypeVisitor( + NotNull> astTypes, + NotNull> astExpectedTypes, + NotNull> astResolvedTypes, + NotNull> astOverloadResolvedTypes, + NotNull arena, + NotNull builtinTypes, + NotNull rootScope + ); + // When we have an assignment, we grab the type of the left-hand-side // and we use it to inform what the type of the right-hand-side ought // to be.

Another week another Luau release 🙂 # Analysis * `InsertionOrderedMap` has been moved from the `Analysis` library to `Common`. * Subtyping has been rewritten to avoid extra allocations: there should be no behavioral change from this effort, only somewhat lower memory pressure. * Fixed a bug where analyzing comparing a value that is too complex to type check against `nil` may cause the type checker to crash. * `pcall` now handles functions that return no values, for example: ```luau local mod = require('mymodule') -- Previously, we would error claiming that we only expect one value on the left-hand-side. -- Now, there is no error and `result` is typed as `unknown`. local success, result = pcall(function() mod.dothething() end) ``` # Compiler * Fixed a bug in `const` where function statements were excluded from const checks. Fixes #2282 ```luau const a = 42 -- The following will now fail to compile. function a() end ``` * Table literal "shapes" can now encorporate constant values at bytecode compile time. We store the shape of constant tables if all their keys are constants, which allows slightly faster insertion when building said literals (we can preallocate a table in a particular shape). Now, we can also store constant values, making construction a single bytecode. For example: ```luau -- This snippet ... return { x = 1, y = 2 } ``` ```luau -- ... used to compile to bytecode like ... DUPTABLE R0 2 LOADN R1 1 SETTABLEKS R1 R0 K0 ['x'] LOADN R1 2 SETTABLEKS R1 R0 K1 ['y'] RETURN R0 1 ``` ```luau -- ... and now compiles to something like ... DUPTABLE R0 4 RETURN R0 1 ``` # Runtime * Introduced a `@debugnoinline` attribute behind a debug flag. We do not actively plan to ship this but have added it to help test compiler and runtime optimizations. * Fixed a bug where setting a breakpoint in a natively compiled function could crash on ARM64. * NCG: The data section of generated code is no longer allocated as executable, preventing a class of potential exploits. --- Co-authored-by: Andy Friesen Co-authored-by: Ariel Weiss Co-authored-by: David Cope Co-authored-by: Hunter Goldstein Co-authored-by: Ilya Rezvov Co-authored-by: Tom Schollenberger Co-authored-by: Vighnesh Vijay Co-authored-by: Karim Mouline --- Analysis/include/Luau/OverloadResolution.h | 81 ---- Analysis/include/Luau/Subtyping.h | 21 +- Analysis/src/AstJsonEncoder.cpp | 11 +- Analysis/src/BuiltinDefinitions.cpp | 50 ++ Analysis/src/BuiltinTypeFunctions.cpp | 94 +--- Analysis/src/Instantiation.cpp | 41 +- Analysis/src/Normalize.cpp | 2 +- Analysis/src/OverloadResolution.cpp | 429 ------------------ Analysis/src/Subtyping.cpp | 229 +++++----- Analysis/src/TypeChecker2.cpp | 19 +- Ast/include/Luau/Ast.h | 1 + Ast/src/Parser.cpp | 46 +- Ast/src/PrettyPrinter.cpp | 8 + CodeGen/include/Luau/CodeAllocator.h | 3 + CodeGen/src/CodeAllocator.cpp | 155 +++++-- CodeGen/src/CodeGenUtils.cpp | 4 +- Common/include/Luau/Bytecode.h | 4 +- .../include/Luau/InsertionOrderedMap.h | 0 Compiler/include/Luau/BytecodeBuilder.h | 4 + Compiler/src/BytecodeBuilder.cpp | 50 +- Compiler/src/Compiler.cpp | 99 +++- Sources.cmake | 2 +- VM/src/lvmload.cpp | 42 ++ tests/AstJsonEncoder.test.cpp | 24 +- tests/CodeAllocator.test.cpp | 97 ++++ tests/Compiler.test.cpp | 113 ++++- tests/OverloadResolver.test.cpp | 47 -- tests/Parser.test.cpp | 71 ++- tests/PrettyPrinter.test.cpp | 11 + tests/RuntimeLimits.test.cpp | 16 + tests/TypeInfer.builtins.test.cpp | 19 + tests/TypeInfer.provisional.test.cpp | 17 +- tests/TypeInfer.tables.test.cpp | 18 +- tests/conformance/tables.luau | 29 +- tools/lldb_formatters.lldb | 14 +- tools/lldb_formatters.py | 149 +++++- 36 files changed, 1081 insertions(+), 939 deletions(-) rename {Analysis => Common}/include/Luau/InsertionOrderedMap.h (100%) diff --git a/Analysis/include/Luau/OverloadResolution.h b/Analysis/include/Luau/OverloadResolution.h index 857cae58..9c88e67d 100644 --- a/Analysis/include/Luau/OverloadResolution.h +++ b/Analysis/include/Luau/OverloadResolution.h @@ -112,14 +112,6 @@ struct OverloadResolution struct OverloadResolver { - enum Analysis - { - Ok, - TypeIsNotAFunction, - ArityMismatch, - OverloadIsNonviable, // Arguments were incompatible with the overloads parameters but were otherwise compatible by arity - }; - OverloadResolver( NotNull builtinTypes, NotNull arena, @@ -141,13 +133,6 @@ struct OverloadResolver Subtyping subtyping; Location callLoc; - // Resolver results - std::vector ok; - std::vector nonFunctions; - std::vector> arityMismatches; - std::vector> nonviableOverloads; - InsertionOrderedMap> resolution; - // Given a (potentially overloaded) function and a set of arguments, test each overload.

Happy spring! 🌷 ### Analysis - Remove an incorrect assertion triggered when we fail to bind a generic pack. - Various miscellaneous fixes for bugs found by the fuzzer. ### Runtime - Fix `DUPTABLE` constant packing not respecting side-effects. - NCG: fix removal of stores that are still needed in VM exits. - NCG: fix a bug that caused buffer access ranges to be computed incorrectly. - Fix #2293. ### Miscellaneous - Various `Makefile` improvements. - Add lldb providers for `Proto`. - Add new `--dump-constants` flag to `luau-compile`. --- Co-authored-by: Andy Friesen Co-authored-by: Ariel Weiss Co-authored-by: David Cope Co-authored-by: Hunter Goldstein Co-authored-by: Sora Kanosue Co-authored-by: Thomas Schollenberger Co-authored-by: Vyacheslav Egorov --- Analysis/include/Luau/ConstraintGenerator.h | 3 + Analysis/src/BuiltinTypeFunctions.cpp | 5 +- Analysis/src/ConstraintGenerator.cpp | 71 +++++- Analysis/src/ConstraintSolver.cpp | 6 +- Analysis/src/DataFlowGraph.cpp | 4 - Analysis/src/Linter.cpp | 3 - Analysis/src/Module.cpp | 12 +- Analysis/src/Subtyping.cpp | 4 +- Analysis/src/TypeChecker2.cpp | 5 - Analysis/src/TypeInfer.cpp | 4 - Ast/include/Luau/Cst.h | 11 - Ast/src/Ast.cpp | 23 +- Ast/src/Cst.cpp | 10 - Ast/src/Parser.cpp | 92 +++----- Ast/src/PrettyPrinter.cpp | 52 +--- CLI/src/Compile.cpp | 25 +- CodeGen/include/Luau/IrUtils.h | 4 +- CodeGen/src/IrLoweringA64.cpp | 4 +- CodeGen/src/IrLoweringX64.cpp | 4 +- CodeGen/src/IrTranslateBuiltins.cpp | 4 +- CodeGen/src/IrTranslation.cpp | 4 +- CodeGen/src/IrUtils.cpp | 4 +- CodeGen/src/OptimizeConstProp.cpp | 9 +- CodeGen/src/OptimizeDeadStore.cpp | 48 +++- Compiler/include/Luau/BytecodeBuilder.h | 1 + Compiler/src/BytecodeBuilder.cpp | 129 +++++----- Compiler/src/Compiler.cpp | 27 ++- Compiler/src/ConstantFolding.cpp | 2 - Compiler/src/CostModel.cpp | 3 - Makefile | 28 ++- tests/Compiler.test.cpp | 67 +++--- tests/Conformance.test.cpp | 6 +- tests/IrBuilder.test.cpp | 14 +- tests/IrLowering.test.cpp | 249 ++++++++++++++------ tests/Linter.test.cpp | 4 - tests/NonStrictTypeChecker.test.cpp | 2 - tests/Parser.test.cpp | 16 -- tests/PrettyPrinter.test.cpp | 3 - tests/RuntimeLimits.test.cpp | 1 - tests/TypeFunction.test.cpp | 3 - tests/TypeInfer.builtins.test.cpp | 2 - tests/TypeInfer.functions.test.cpp | 24 ++ tests/TypeInfer.generics.test.cpp | 1 - tests/TypeInfer.oop.test.cpp | 1 - tests/TypeInfer.tables.test.cpp | 104 +------- tests/TypeInfer.test.cpp | 110 +++++++++ tests/TypeInfer.typeInstantiations.test.cpp | 24 -- tests/conformance/stringinterp.luau | 1 + tests/conformance/tables.luau | 14 ++ tools/lldb_formatters.lldb | 6 +- tools/lldb_formatters.py | 87 ++++++- 51 files changed, 785 insertions(+), 555 deletions(-) diff --git a/Analysis/include/Luau/ConstraintGenerator.h b/Analysis/include/Luau/ConstraintGenerator.h index 21c8a27b..c8ee75af 100644 --- a/Analysis/include/Luau/ConstraintGenerator.h +++ b/Analysis/include/Luau/ConstraintGenerator.h @@ -13,6 +13,7 @@ #include "Luau/NotNull.h" #include "Luau/Polarity.h" #include "Luau/Refinement.h" +#include "Luau/Set.h" #include "Luau/Symbol.h" #include "Luau/TypeFwd.h" #include "Luau/TypeIds.h" @@ -178,6 +179,8 @@ struct ConstraintGenerator std::vector unionsToSimplify; + Set uninitializedGlobals{nullptr}; + Polarity polarity = Polarity::None; DenseHashMap, TypeId, PairHash> propIndexPairsSeen{{nullptr, ""}}; diff --git a/Analysis/src/BuiltinTypeFunctions.cpp b/Analysis/src/BuiltinTypeFunctions.cpp index 15049539..6bda6060 100644 --- a/Analysis/src/BuiltinTypeFunctions.cpp +++ b/Analysis/src/BuiltinTypeFunctions.cpp @@ -22,6 +22,7 @@ LUAU_DYNAMIC_FASTINTVARIABLE(LuauStepRefineRecursionLimit, 64) LUAU_FASTFLAG(LuauOverloadGetsInstantiated) LUAU_FASTFLAGVARIABLE(LuauTypeFunctionsCaptureNestedInstances) +LUAU_FASTFLAGVARIABLE(LuauTypeFunctionsAddFreeTypePackWithPositivePolarity) namespace Luau { @@ -145,7 +146,9 @@ static std::optional solveFunctionCall(NotNull if (!selected.overload.has_value()) return std::nullopt; - TypePackId retPack = ctx->arena->freshTypePack(ctx->scope); + TypePackId retPack = FFlag::LuauTypeFunctionsAddFreeTypePackWithPositivePolarity + ? ctx->arena->freshTypePack(ctx->scope, Polarity::Positive) + : ctx->arena->freshTypePack(ctx->scope); TypeId prospectiveFunction = ctx->arena->addType(FunctionType{argsPack, retPack}); // FIXME: It's too bad that we have to bust out the Unifier here.

charset=UTF-8 Content-Transfer-Encoding: 8bit The Luau team has been cooking for this week's release! 🍳 We have implemented an initial version of the [64-bit Integer Type](https://rfcs.luau.org/type-long-integer.html)! Please keep in mind that although the RFC has been accepted, we are currently in the process of identifying and fixing bugs, which may require amending the original RFC. Additionally, we've been working on the following: ### Analysis - Fix crash reported in #2305. - Reword type-function error messages. - Fix various crashes found by fuzzer and in unit tests. - Rework how we track generalizable free types. ### Runtime - NCG: Propagate register tags across block chains. - NCG: Fix a bug in how register information was set up when entering a new block. - NCG: Fix a bug where register tag information for non-live registers was incorrectly propagated. - NCG: Remove duplicate stores of doubles and integers. - NCG: Unconditionally provide tags to read/write functions for buffers. ### Miscellaneous - Various Makefile, lldb_formatter, and lldb-dap improvements. --- Co-authored-by: Ariel Weiss Co-authored-by: David Cope Co-authored-by: Hunter Goldstein Co-authored-by: James McNellis Co-authored-by: Sora Kanosue Co-authored-by: Thomas Schollenberger Co-authored-by: Vyacheslav Egorov --------- Co-authored-by: Vyacheslav Egorov Co-authored-by: Ariel Weiss Co-authored-by: Andy Friesen Co-authored-by: Hunter Goldstein Co-authored-by: Varun Saini <61795485+vrn-sn@users.noreply.github.com> --- Analysis/include/Luau/Constraint.h | 10 +- Analysis/include/Luau/ConstraintGenerator.h | 2 +- Analysis/include/Luau/ConstraintSolver.h | 34 +- Analysis/include/Luau/Error.h | 9 + Analysis/include/Luau/Instantiation2.h | 7 +- Analysis/include/Luau/Normalize.h | 28 +- Analysis/include/Luau/OrderedSet.h | 1 + Analysis/include/Luau/OverloadResolution.h | 1 -

Another week, another release 🌺 🐰 This week we've made some major performance boosts for property accesses, feature fixes, as well as our regular bug fixes and improvements! ### Analysis * `Luau/OverloadResolution.h` has been renamed to `Luau/OverloadResolver.h` (to match the struct name) * Added syntax highlighting for the `const` keyword! * Fixed an internal compiler error that could occur when type checking erroneous uses of `const`, for example: ```luau -- This is not a valid `const` declaration as we require that `const` declarations -- have values, as it is almost certainly a mistake if they don't (as you cannot assign -- to them later). Previously this _also_ caused an ICE in the new solver, which is not -- desirable. const foobar return foobar ``` * Fixed a bug that could result in function calls failing to type check due to ungeneralized free types: ```luau function add(a, b) return a + b end local vec2 = {} function vec2.new(x, y) return setmetatable({ x = x or 0, y = y or 0 }, { __add = function(v1, v2) return { x = v1.x + v2.x, y = v1.y + v2.y } end, }) end -- Prior, this would fail to type check and we'd get warnings -- about ungeneralized types (`number <: 'a` isn't a subtype of blah) local a = add(vec2.new(0, 0), vec2.new(1, 1)) ``` * Fixed a bug where `type(x) == "vector"` always refined `x` to `never`: ```luau local x: unknown if type(x) == "vector" then local y = x -- Prior, x would be `never` end ``` ### Compiler & Runtime * 10-30% performance improvement for Luau userdata property accesses via new property descriptor bytecode caching * Increased precision for `math.noise()` * Fixed a bug where generic `for` loops were incorrectly optimized when the global environment was modified ```luau local env = getfenv(1) env.next = {1, 2, 3} -- This will now disable `LOP_FORGPREP_NEXT` optimization, and run successfully local ok, err = pcall(function() for k, v in next, {} do end end) ``` * Added 64-bit Integer output to the AST Json Encoder, and fixed some bugs from the initial implementation * NCG: fixed an issue where certain fast-call sequences with multiple return values could cause incorrect register tracking * NCG: improved compiler performance by caching register tags and computing them only when consumed by an instruction ### Miscellaneous * Improved `lldb` debugger support by adding visualization for `lua_State`, including a new `set_userdata_type_name` method to configure the debugger for custom `userdata` structures. -------------------------------------- Thank you to all our contributors this week!

Sorry for the late release, but it's another week and another Luau release, though really more of a Luau VM release this time around 🙂 # Runtime * Added `FASTCALL` support for `buffer.writeinteger` and `buffer.readinteger` (#2326) * NCG: Fixed a bug in which `buffer` writes did not invalidate the heap data of buffers. In practice this did not occur due to this codepath mostly incuring a VM exit, but the bug was visible in the IR output. * NCG: Reworked how we track whether IR instructions return values, fixing a class of performance issues (increased register pressure from dead instructions) and potential correctness issues. * NCG: Avoid potentially spilling a register _onto_ the frame pointer on ARM, which could cause unwinding crashes or other issues while debugging. * NCG: Fixed a bug in the NCG integer implementation where optimizing a comparison to an integer would cause us to jump to a nonsense position (the arguments given to `JUMP` were erroneous). * NCG: Fixed a bug where writes to `userdata` would not invalidate the store cache, meaning we may incorrectly assume a read result has not changed. * NCG: Improved how values are passed between function calls on x86, opening up further optimization opportunities by avoiding some register spills. --- Co-authored-by: Ariel Weiss Co-authored-by: Sora Kanosue Co-authored-by: Thomas Schollenberger Co-authored-by: Vyacheslav Egorov --------- Co-authored-by: Vyacheslav Egorov Co-authored-by: Ariel Weiss Co-authored-by: Andy Friesen Co-authored-by: Varun Saini <61795485+vrn-sn@users.noreply.github.com> Co-authored-by: Sora Kanosue Co-authored-by: Annie Tang Co-authored-by: Annie Tang <98965493+annieetang@users.noreply.github.com> --- Analysis/src/ConstraintGenerator.cpp | 3 +- Analysis/src/EmbeddedBuiltinDefinitions.cpp | 123 +----------- Analysis/src/Error.cpp | 16 +- Analysis/src/TypeChecker2.cpp | 5 +- Analysis/src/TypeFunctionRuntime.cpp | 8 +- Ast/src/Parser.cpp | 4 +- CodeGen/include/Luau/IrCallWrapperX64.h | 6 + CodeGen/include/Luau/IrUtils.h | 10 +- CodeGen/src/BytecodeAnalysis.cpp | 11 ++ CodeGen/src/EmitCommonA64.h | 2 - CodeGen/src/EmitCommonX64.h | 10 +- CodeGen/src/IrCallWrapperX64.cpp | 27 +++ CodeGen/src/IrLoweringA64.cpp | 37 +++- CodeGen/src/IrLoweringX64.cpp | 199 ++++++++++++++------ CodeGen/src/IrRegAllocA64.cpp | 45 ++++- CodeGen/src/IrRegAllocX64.cpp | 16 +- CodeGen/src/IrUtils.cpp | 1 + CodeGen/src/OptimizeConstProp.cpp | 34 +++- CodeGen/src/OptimizeDeadStore.cpp | 6 + Common/include/Luau/Bytecode.h | 4 + Compiler/src/Builtins.cpp | 9 + Compiler/src/Types.cpp | 2 + Makefile | 5 +- VM/src/lbuiltins.cpp | 42 +++++ VM/src/lgc.cpp | 4 +- VM/src/lstate.cpp | 4 +- VM/src/lvmload.cpp | 4 +- tests/Compiler.test.cpp | 41 ++++ tests/Conformance.test.cpp | 53 ++++-- tests/IrBuilder.test.cpp | 154 +++++++++++++++ tests/IrLowering.test.cpp | 139 +++++++++++++- tests/Parser.test.cpp | 5 +- tests/TypeFunction.user.test.cpp | 3 +- tests/TypeInfer.classes.test.cpp | 37 +--- tests/TypeInfer.definitions.test.cpp | 12 +- tests/TypeInfer.refinements.test.cpp | 3 - tests/conformance/integers.luau | 38 ++++ 37 files changed, 815 insertions(+), 307 deletions(-) diff --git a/Analysis/src/ConstraintGenerator.cpp b/Analysis/src/ConstraintGenerator.cpp index d9c66192..7558f2ab 100644 --- a/Analysis/src/ConstraintGenerator.cpp +++ b/Analysis/src/ConstraintGenerator.cpp @@ -2074,7 +2074,8 @@ ControlFlow ConstraintGenerator::visit(const ScopePtr& scope, AstStatDeclareExte for (const AstDeclaredExternTypeProperty& externProp : declaredExternType->props) { Name propName(externProp.name.value);

Date: Mon, 27 Apr 2026 14:03:39 +0100 Subject: [PATCH 12/61] Avoid a redundant MOVE on some string interpolation setups (#2324) This fixes a discrepancy between string interpolation (local a = \`{xyz}\`) and the manually written equivilant version (`local a = ("%*"):format(xyz)`), where string interpolation would sometimes introduce a `MOVE` even when it didn't need to as the target register was marked as temporary

Bytecode difference Code: local f = \`{global}\` Before: ``` Function 0 (??): 1: local f = `{global}` LOADK R1 K0 ['%*'] GETGLOBAL R3 K1 ['global'] NAMECALL R1 R1 K2 ['format'] CALL R1 2 1 MOVE R0 R1 RETURN R0 0 ``` After: ``` Function 0 (??): 1: local f = `{global}` LOADK R0 K0 ['%*'] GETGLOBAL R2 K1 ['global'] NAMECALL R0 R0 K2 ['format'] CALL R0 2 1 RETURN R0 0 ```
This is also technically a performance improvement, though the difference is mostly unnoticeable in normal contexts (I'm seeing a 4-5% improvement on a 1e7 loop which is nothing but the optimisable string interp, so about as good as the case gets) I've not written a new test case as `InterpStringRegisterCleanup` already covers the unoptimisable case --- Compiler/src/Compiler.cpp | 10 +++++-- tests/Compiler.test.cpp | 57 ++++++++++++++++++++------------------- 2 files changed, 38 insertions(+), 29 deletions(-) diff --git a/Compiler/src/Compiler.cpp b/Compiler/src/Compiler.cpp index a6637463..c27afdb6 100644 --- a/Compiler/src/Compiler.cpp +++ b/Compiler/src/Compiler.cpp @@ -33,6 +33,7 @@ LUAU_FASTFLAGVARIABLE(LuauCompileDuptableConstantPack2) LUAU_FASTFLAGVARIABLE(LuauCompileVectorReveseMul) LUAU_FASTFLAG(LuauIntegerType) LUAU_FASTFLAGVARIABLE(LuauCompileStringInterpWithZero) +LUAU_FASTFLAGVARIABLE(LuauCompileStringInterpTargetTop) LUAU_FASTFLAGVARIABLE(LuauCompileNoOptNext) LUAU_FASTFLAG(DebugLuauNoInline) @@ -2009,7 +2010,11 @@ struct Compiler RegScope rs(this); - uint8_t baseReg = allocReg(expr, unsigned(2 + expr->expressions.size - skippedSubExpr)); + unsigned int regCount = unsigned(2 + expr->expressions.size - skippedSubExpr); + + // Optimization: have the format call place the result directly into the target to avoid an extra MOVE + bool targetTop = FFlag::LuauCompileStringInterpTargetTop && targetTemp && target == regTop - 1; + uint8_t baseReg = targetTop ?

We have another weekly release of Luau for you with updates in multiple areas. ### What's New * Added `lua_registeruserdatadirectfieldget` API to register fastcall-like handlers for tagged userdata property reads. Without call frame creation and Luau state interaction, simple values can be fetched up to 4x faster. ### Analysis * Fixed an issue where `any` when used as part of a table type was not correctly suppressing errors. Closes #2341 ```luau type Foo = { kind: "foo", foo: T } type Bar = { kind: "bar", bar: T } type FooBar = Foo | Bar local function f(x: Foo): FooBar -- This used to error prior, despite the `any` that should allow for error suppression. return x end ``` * Fixed one of the frequent cases for internal analysis errors related to cyclic types ### Compiler * Added constant propagation for table fields: ```luau local config = { a = 2, b = 4 } local function foo(x) return x * config.a -- config table is not captured and there is no runtime field lookup end ``` For the optimization to take place, table cannot be directly or indirectly modified. We expect that some of the restrictions will get lifted in the future. ### Runtime * Fixed an issue with `lua_registeruserdatadirectaccess` API when a `newproxy` object is encountered ### Native Code Generation * Added native lowering for `buffer.readinteger` and `buffer.writeinteger` * Added 'nopPadding' code generation option which inserts nop instructions to randomize code layout * Fixed handling of `integer.min/max/clamp` fastcalls which could produce an incorrect result before * Fixed buffer read/write operations with constant offsets incorrectly taking a VM assist when last byte is touched ### Miscellaneous * luau and luau-compile binaries now accept --codegen-cold option to natively compile all functions --- Co-authored-by: Andy Friesen Co-authored-by: Hunter Goldstein Co-authored-by: Karim Mouline Co-authored-by: Sora Kanosue Co-authored-by: Thomas Schollenberger Co-authored-by: Varun Saini Co-authored-by: Vyacheslav Egorov --- Analysis/include/Luau/Subtyping.h | 9 + Analysis/include/Luau/SubtypingUnifier.h | 3 +- Analysis/include/Luau/TypeFunction.h | 5 - Analysis/include/Luau/TypeUtils.h | 10 + Analysis/include/Luau/Unifier2.h | 12 +- Analysis/src/BuiltinDefinitions.cpp | 4 +- Analysis/src/BuiltinTypeFunctions.cpp | 15 +- Analysis/src/ConstraintGenerator.cpp | 25 +- Analysis/src/ConstraintSolver.cpp | 139 +++-- Analysis/src/EmbeddedBuiltinDefinitions.cpp | 62 +-- Analysis/src/Subtyping.cpp | 551 +++++++++----------- Analysis/src/SubtypingUnifier.cpp | 40 +- Analysis/src/TypeChecker2.cpp | 85 ++- Analysis/src/TypeFunction.cpp | 28 +- Analysis/src/TypeFunctionRuntime.cpp | 7 +- Analysis/src/TypeUtils.cpp | 27 + Analysis/src/Unifier2.cpp | 198 ++----- Bytecode/src/BytecodeGraph.cpp | 10 +- CLI/src/Compile.cpp | 8 +- CLI/src/Repl.cpp | 12 + CodeGen/include/Luau/AssemblyBuilderA64.h | 2 + CodeGen/include/Luau/CodeGenOptions.h | 4 + CodeGen/include/Luau/IrData.h | 14 + CodeGen/include/Luau/IrUtils.h | 1 + CodeGen/include/Luau/IrVisitUseDef.h | 25 +- CodeGen/src/AssemblyBuilderA64.cpp | 7 + CodeGen/src/CodeGen.cpp | 1 + CodeGen/src/CodeGenContext.cpp | 21 + CodeGen/src/CodeGenContext.h | 5 + CodeGen/src/CodeGenLower.h | 25 + CodeGen/src/CodeGenUtils.cpp | 31 ++ CodeGen/src/IrDump.cpp | 4 + CodeGen/src/IrLoweringA64.cpp | 38 +- CodeGen/src/IrLoweringX64.cpp | 39 +- CodeGen/src/IrTranslateBuiltins.cpp | 83 ++- CodeGen/src/IrUtils.cpp | 3 + CodeGen/src/IrValueLocationTracking.cpp | 15 +- CodeGen/src/OptimizeConstProp.cpp | 25 +- CodeGen/src/OptimizeDeadStore.cpp | 2 + Compiler/src/BuiltinFolding.cpp | 25 +- Compiler/src/Compiler.cpp | 35 +- Compiler/src/ConstantFolding.cpp | 505 +++++++++++++++++- Compiler/src/ConstantFolding.h | 2 + Compiler/src/CostModel.cpp | 8 +- Compiler/src/Types.cpp | 14 +- Sources.cmake | 1 + VM/include/lua.h | 24 + VM/src/lapi.cpp | 61 +++ VM/src/lgc.cpp | 14 +- VM/src/lmathlib.cpp | 25 +- VM/src/lperf.cpp | 1 + VM/src/lstate.cpp | 37 +- VM/src/lstate.h | 6 +- VM/src/ludata.h | 3 + VM/src/lvmexecute.cpp | 34 +- VM/src/lvmload.cpp | 4 +- tests/AssemblyBuilderA64.test.cpp | 41 ++ tests/Compiler.test.cpp | 252 ++++++++- tests/Conformance.test.cpp | 156 +++++- tests/DirectFieldAccess.test.cpp | 313 +++++++++++ tests/FragmentAutocomplete.test.cpp | 3 - tests/IrLowering.test.cpp | 86 ++- tests/NonstrictMode.test.cpp | 2 - tests/Normalize.test.cpp | 2 - tests/Subtyping.test.cpp | 5 - tests/TypeFunction.test.cpp | 3 - tests/TypeFunction.user.test.cpp | 2 - tests/TypeInfer.annotations.test.cpp | 10 +- tests/TypeInfer.builtins.test.cpp | 6 - tests/TypeInfer.classes.test.cpp | 13 +- tests/TypeInfer.functions.test.cpp | 23 +- tests/TypeInfer.intersectionTypes.test.cpp | 119 +---- tests/TypeInfer.provisional.test.cpp | 4 - tests/TypeInfer.singletons.test.cpp | 5 +- tests/TypeInfer.tables.test.cpp | 111 +++- tests/TypeInfer.test.cpp | 30 +- tests/TypeInfer.typeInstantiations.test.cpp | 8 +- tests/TypeInfer.unionTypes.test.cpp | 15 +- tests/conformance/buffers.luau | 51 ++ tests/conformance/integers.luau | 89 ++++ tests/conformance/native.luau | 77 +++ tests/conformance/tables.luau | 139 +++++ 82 files changed, 2787 insertions(+), 1172 deletions(-) create mode 100644 tests/DirectFieldAccess.test.cpp diff --git a/Analysis/include/Luau/Subtyping.h b/Analysis/include/Luau/Subtyping.h index 7036eec3..280179cc 100644 --- a/Analysis/include/Luau/Subtyping.h +++ b/Analysis/include/Luau/Subtyping.h @@ -304,6 +304,15 @@ struct Subtyping bool forceCovariantTest, NotNull scope );

From: ariel Date: Fri, 8 May 2026 13:41:30 -0700 Subject: [PATCH 16/61] Sync to upstream/release/720 (#2383) Howdy there, folks! We've got another Luau release this week, mainly focused on some pain points with type analysis! **Note**: For folks who are using definition files for providing type definitions for the runtime environment they're working in, we also wanted to highlight that the `declare class` syntax is being entirely cleaned up finally. We added syntax for `declare extern type` many months ago, and with the [Luau classes RFC](https://rfcs.luau.org/syntax-classes.html) accepted, it is particularly prudent that we finalize the cleanup of `declare class`. If you're still on the old syntax, please update to use `declare extern type Foo with ...` to avoid interruption when a future release removes `declare class` entirely. ## Language * The `const` keyword now correctly appears in autocomplete suggestions from Luau. ## Analysis - Fixes false positive `OptionalValueAccess` errors when iterating over a table with an optional indexer type. The VM's generalized iteration already guarantees non-nil values in the loop body, and the type checker now reflects that. Fixes [luau-lang/luau#2236](https://github.com/luau-lang/luau/issues/2236). ```luau --!strict type TypeA = { Value: any } local list = {} :: { [string]: TypeA? } for index, a in list do a.Value = 1 -- No longer incorrectly reported as 'TypeA?' could be nil end ``` - Improves bidirectional type inference for unions of tables and functions. Table literals that clearly match one branch of a union are no longer falsely rejected: ```luau --!strict type FnRecord = { handler: (number) -> string, label: string? } type StrRecord = { handler: string, label: string? } type Record = FnRecord | StrRecord -- Previously flagged as not a subtype of `Record`; now correctly accepted as a FnRecord local r: Record = { handler = function(input) return tostring(input) end, label = "test", } ``` - Fixes a crash that could occur when `typeof` is used inside the type arguments of an instantiated method call: ```luau local t = {} function t:f() end local x = 42 t:f<>() -- No longer crashes ``` - Fixes missing autocomplete suggestions for string singleton types when the expected type is an intersection containing a string singleton (e.g. `"Foo" & "Foo"` or `keyof & T`). ## Compiler - Fixes a discrepancy where string interpolation would sometimes emit a redundant `MOVE` instruction that an equivalent `string.format` call would not, when the target register was already correct.

We have a few nice new things to share: ## Language * Add support for read-only indexers using the syntax `{read T}` or `{read [K]: V}`. Read-only indexers are really useful for functions that accept an array, but don't modify it because calls to such a function can be tested covariantly rather than invariantly: ```luau function print_them_old(a: {Instance}) ... end function print_them_new(a: {read Instance}) ... end local players: {Players} = ... -- We have to reject this call because, for all we know, the -- function could insert non-Players into our Player array! print_them_old(players) -- This function is not allowed to write to the array so -- everything is fine. print_them_new(players) ``` * Fix a unification bug that would result in incorrect inference in cases like `'a <: T | nil` where `'a` is a free type and `T` is an instantiated generic. This would result in incorrect inferences in cases like the following: ```luau local function f(a: T & string): T return a end local b = f("hello") local c = f(("world" :: string)) ``` * First steps toward implementing classes. See [the RFC](https://github.com/luau-lang/rfcs/blob/master/docs/syntax-classes.md) for details. ## Analysis * Ensure that inferred arguments to functions are instantiated. This fixes a class of bugs that could cause type inference to hang and consume lots of memory. * Improve the error that's reported when two table types are only incompatible because of a read/write restriction. This fixes cases where we would report nonsense errors like "number is not a subtype of number." * We had an issue where passing a function type through a type function would cause type inference to discard the data about the parameters' names even if the type was returned verbatim. This is now fixed. ## Interpreter * Adjust the FASTCALL3 inlining cost model to line up with other fastcalls. * Reduce Luau VM interpreter loop stack pressure in Debug/NoOpt builds * Optimize the constant folding pass in the compiler ## Native Code Generation * Introduce ExitSync blocks to help avoid synchronizing the VM stack unnecessarily. * NCG VM exit sync cannot include register from blocks not in a chain. * Add CALLFB instruction and feedback vectors in proto. This will be used to help the runtime know which function calls can be inlined. * Handle repeated IrCmd::LOAD_ENV and switch from table RegisterLink information to SSA info. ## General * You can now pass `--solver=new` or `--solver=old` to `luau-analyze` tool to select the solver you'd like to use. It defaults to the new solver. ## Internal Contributors Co-authored-by: Andy Friesen Co-authored-by: Annie Tang Co-authored-by: Ariel Weiss Co-authored-by: Hunter Goldstein Co-authored-by: Ilya Rezvov Co-authored-by: Sora Kanosue Co-authored-by: Vighnesh Vijay Co-authored-by: Vyacheslav Egorov --------- Co-authored-by: Vyacheslav Egorov Co-authored-by: Ariel Weiss Co-authored-by: Hunter Goldstein Co-authored-by: Varun Saini <61795485+vrn-sn@users.noreply.github.com> Co-authored-by: Sora Kanosue Co-authored-by: Annie Tang Co-authored-by: Annie Tang <98965493+annieetang@users.noreply.github.com> Co-authored-by: Ilya Rezvov --- Analysis/include/Luau/ConstraintGenerator.h | 11 + Analysis/include/Luau/ConstraintSolver.h | 10 -

A somewhat small set of release notes for this week, but don't mistake it for being unexciting because ... ## Yielding iterators Luau now supports yielding within iterators! This affords code patterns such as being able to iterate over the results of an IO bound operation, e.g.: ```luau -- `net.serve` here could return a generator and the requisite initial state, -- and said generator can now yield to wait for IO! for request in net.serve(8080) do request.respondWith("Echo: " .. request.body) end ``` Note: yielding in metamethods is *still* unsupported, including `__iter`. Fixes https://github.com/luau-lang/luau/issues/838. ## Ast * Added concrete syntax tree support for expression groups and type groups ```luau -- In the CST, we will now preserve whitespace here ... local x = (1 + 2 ) -- ... and here ... type t = (number ) ``` ## Runtime * Introduced a new `CMPPROTO` bytecode instruction to be used with just-in-time bytecode inlining. * NCG: Fixed a bug where an optimization pass would cause us to treat a known `nil` value as potentially garbage collected. --- Co-authored-by: Andy Friesen Co-authored-by: Annie Tang Co-authored-by: Hunter Goldstein Co-authored-by: Ilya Rezvov Co-authored-by: Sora Kanosue Co-authored-by: Vighnesh Vijay Co-authored-by: Vyacheslav Egorov --- Analysis/include/Luau/Constraint.h | 1 -

e7500c93a7f78803baa4f14118fd95cd3a183cf0 Mon Sep 17 00:00:00 2001 From: Varun Saini <61795485+vrn-sn@users.noreply.github.com> Date: Fri, 29 May 2026 15:00:40 -0700 Subject: [PATCH 22/61] Sync to upstream/release/723 (#2419) Another week, another release! ### What's new? - Implement export semantics as described in https://github.com/luau-lang/rfcs/pull/179. ### Analysis - Use sentinel `Position`s in the CST rather than `std::optional` to reduce memory pressure. ### Runtime - Compiler: Improve dump output for Luau table constants (e.g. when using `luau-compile`). - NCG: Record block exit info for all blocks. - NCG: Reduce spill pressure by using dead VM register store locations. --- Co-authored-by: Andy Friesen Co-authored-by: Ariel Weiss Co-authored-by: Hunter Goldstein

<125769645+ActualMasterOogway@users.noreply.github.com> Date: Wed, 3 Jun 2026 15:12:15 +0200 Subject: [PATCH 23/61] Fix missing `prettyPrint` overloads in header and implementation (#2209) This PR fixes a discrepancy between `Ast/include/Luau/PrettyPrinter.h` and `Ast/src/PrettyPrinter.cpp`. The header declared `std::string prettyPrint(AstStatBlock& ast);` but the implementation was missing. The implementation had `std::string prettyPrint(AstStatBlock& block, const CstNodeMap& cstNodeMap)` but it was not declared in the header. Changes: - Added `std::string prettyPrint(AstStatBlock& block, const CstNodeMap& cstNodeMap);` to `PrettyPrinter.h`. - Implemented `std::string prettyPrint(AstStatBlock& block)` in `PrettyPrinter.cpp` (delegating to the 2-arg version). - Added a unit test to verify `prettyPrint(AstStatBlock&)` works correctly. --- Fixes #2206 --------- Co-authored-by: vegorov-rbx <75688451+vegorov-rbx@users.noreply.github.com> --- Ast/include/Luau/PrettyPrinter.h | 3 ++- Ast/src/PrettyPrinter.cpp | 5 +++++ tests/PrettyPrinter.test.cpp | 13 +++++++++++++ 3 files changed, 20 insertions(+), 1 deletion(-) diff --git a/Ast/include/Luau/PrettyPrinter.h b/Ast/include/Luau/PrettyPrinter.h index 6a28a47c..423c61e1 100644 --- a/Ast/include/Luau/PrettyPrinter.h +++ b/Ast/include/Luau/PrettyPrinter.h @@ -23,7 +23,8 @@ std::string toString(AstNode* node);

Check out what's new: ### Analysis * Fixes an error where Luau script analysis would sometimes incorrectly infer that `Library.table.unpack` returns `...unknown` * Writing a recursive generic type alias with the wrong number of generics now reports one more specific error rather than two. * Fixed a crash that could happen when normalizing an exceptionally large negated type. * Improved performance in constraint solving when reducing large nested type functions. * Fixed a crash that could happen when combining `export` and `class`. ### Compiler & Runtime * Luau C API will now auto-reserve required stack slots to reduce API errors, eliminating the need for manual stack management with `lua_checkstack` * Add support for yieldable protected C calls for custom Luau libraries via `luaL_pcallyieldable` * NCG: Remove the use of shared execution callback data for register spills * Updates the garbage collector to visit cached tagged userdata metatables, preventing premature collection and making the lua_setuserdatametatable API less error-prone. * Fixed two compiler crashes related to `export`. ----------------- As always, thanks to all our contributors, and happy pride and FIFA world cup!!! 🏳️‍🌈 ⚽️ 🏆 Co-authored-by: Andy Friesen Co-authored-by: Annie Tang Co-authored-by: Ariel Weiss Co-authored-by: Hunter Goldstein Co-authored-by: Sora Kanosue Co-authored-by: Thomas Schollenberger Co-authored-by: Varun Saini Co-authored-by: Vighnesh Vijay Co-authored-by: Vyacheslav Egorov --------- Co-authored-by: Vyacheslav Egorov Co-authored-by: Ariel Weiss Co-authored-by: Andy Friesen Co-authored-by: Hunter Goldstein Co-authored-by: Varun Saini <61795485+vrn-sn@users.noreply.github.com> Co-authored-by: Sora Kanosue Co-authored-by: Ilya Rezvov --- Analysis/include/Luau/ConstraintGenerator.h | 4 +- Analysis/include/Luau/SubtypingUnifier.h | 3 -

In practice this means messages that used to be multiple lines explaining why each element in the union did not relate to the other type are replaced with a single message. - Fix an error caused by improperly rebinding an erroneous type participating in a cyclic alias. Specifically: ``` type A = B type B = { x: C } type C = A ``` no longer triggers an assertion. - Requirers of a module will now see an error type instead of an erroneous type function, which will reduce the amount of cascading errors displayed. - Fixes a bug where nilable generic functions would erroneously claim there is a generic bounds mismatch. Fixes #2393 ## Runtime - General improvements to the Bytecode Graph, including better parsing, serialization, and inlining. ## Miscellaneous: - Reduce stack usage in Luau's parser - Adds support for attribute lists and parametrized attributes to the CST - OSS Contribution: Fixes how the CFG dumps refinement instructions --- Co-authored-by: Andy Friesen Co-authored-by: Hunter Goldstein Co-authored-by: Ilya Rezvov Co-authored-by: James McNellis Co-authored-by: Sora Kanosue Co-authored-by: Thomas Schollenberger Co-authored-by: Vighnesh Vijay --- Analysis/include/Luau/Subtyping.h | 1 + Analysis/src/ConstraintSolver.cpp | 11 +- Analysis/src/Module.cpp | 6 + Analysis/src/NonStrictTypeChecker.cpp | 19 +- Analysis/src/Subtyping.cpp | 57 ++++ Ast/include/Luau/Cst.h | 38 +++ Ast/include/Luau/Parser.h | 41 ++- Ast/src/Cst.cpp | 44 +++ Ast/src/Parser.cpp | 309 +++++++++++++++++--- Ast/src/PrettyPrinter.cpp | 150 +++++++++- Bytecode/include/Luau/BytecodeBuilder.h | 15 +- Bytecode/include/Luau/BytecodeCallInliner.h | 67 ++++- Bytecode/include/Luau/BytecodeGraph.h | 76 +++++ Bytecode/include/Luau/BytecodeOps.h | 13 + Bytecode/src/BytecodeBuilder.cpp | 241 +++++++++++---- Bytecode/src/BytecodeGraphParser.h | 42 +-- Bytecode/src/BytecodeGraphSerializer.h | 13 +- Common/include/Luau/Bytecode.h | 2 +- Compiler/src/Compiler.cpp | 85 ++---- extern/doctest.h | 4 + tests/BytecodeCallInliner.test.cpp | 28 +- tests/Compiler.test.cpp | 21 -- tests/Conformance.test.cpp | 2 + tests/NonstrictMode.test.cpp | 3 - tests/PrettyPrinter.test.cpp | 111 ++++++- tests/TypeFunction.test.cpp | 28 ++ tests/TypeInfer.aliases.test.cpp | 25 ++ tests/TypeInfer.externTypes.test.cpp | 20 +- tests/TypeInfer.intersectionTypes.test.cpp | 43 +-- tests/TypeInfer.singletons.test.cpp | 17 +- tests/TypeInfer.typeInstantiations.test.cpp | 15 +- tests/TypeInfer.unionTypes.test.cpp | 95 +++++- 32 files changed, 1298 insertions(+), 344 deletions(-) diff --git a/Analysis/include/Luau/Subtyping.h b/Analysis/include/Luau/Subtyping.h index b7693602..b85dcc16 100644 --- a/Analysis/include/Luau/Subtyping.h +++ b/Analysis/include/Luau/Subtyping.h @@ -284,6 +284,7 @@ struct Subtyping template SubtypingResult isInvariantWith(SubtypingEnvironment& env, const TryPair& pair, NotNull);

To activate it `Luau::JitInliner::setup` should be called on `lua_State`. To use it in conformance tests or luau CLI `--jit-inliner` flag should be passed. ## GC - fixed incorrect reporting of visited bytes for tables ## CodeGen - DSE hints should only be provided for full tag+value kills ## Typing - Variadic type annotations are now "pushed" into arguments ```luau local foo: { read bar: (...string) -> () } = { -- Prior, `foobar` would be of type `unknown`, but the clear intent is for `foobar` to be -- of type `string`. bar = function (foobar) print(foobar) end } ``` - Disallow `extern class` declaration syntax - When subtype testing a type like nil <: T?, don't bind the generic. ```luau local function createElement

(component: (P) -> any, props: P?): any return nil end local function MyComponent(props: { x: number, y: number? }) return nil end -- Prior, when inferring the instantiation of `createElement`, we'd end up -- collecting a bound of `nil` for `P` due to an interaction between generic -- inference and width subtyping, which ended up in incoherent bounds for -- `P`, ultimately preventing us from type checking it. createElement(MyComponent, { x = 1 }) ```l - Disable bidirectional function inference of return types if the function is ambiguous ```luau local function useEffect(callback: (() -> ()) | (() -> () -> ()), deps: {any}?): () end -- Both `() -> ()` and `() -> () -> ()` are valid options to push into this first lambda, -- but without inferring the _inner_ lambda we do not know that we need to push the -- second, so we opt to _not_ push the return type in at all. useEffect(function() return function() end end) ``` ## Misc - Makes Luau::Set pick the null tombstone by default when the key is a pointer type - Make DenseHashMap/Set optionally default initializable when the key is a pointer type Co-authored-by: Andy Friesen [afriesen@roblox.com](mailto:afriesen@roblox.com) Co-authored-by: Hunter Goldstein [hgoldstein@roblox.com](mailto:hgoldstein@roblox.com) Co-authored-by: Ilya Rezvov [irezvov@roblox.com](mailto:irezvov@roblox.com) Co-authored-by: James McNellis [jmcnellis@roblox.com](mailto:jmcnellis@roblox.com) Co-authored-by: Sora Kanosue [skanosue@roblox.com](mailto:skanosue@roblox.com) Co-authored-by: Thomas Schollenberger [tschollenberger@roblox.com](mailto:tschollenberger@roblox.com) Co-authored-by: Vighnesh Vijay [vvijay@roblox.com](mailto:vvijay@roblox.com) --------- Co-authored-by: Vyacheslav Egorov Co-authored-by: Ariel Weiss Co-authored-by: Andy Friesen Co-authored-by: Hunter Goldstein Co-authored-by: Varun Saini <61795485+vrn-sn@users.noreply.github.com> Co-authored-by: Sora Kanosue Co-authored-by: Annie Tang Co-authored-by: Annie Tang <98965493+annieetang@users.noreply.github.com> Co-authored-by: Vighnesh Vijay --- Analysis/include/Luau/Constraint.h | 6 +- Analysis/include/Luau/ConstraintGraph.h | 2 +- Analysis/include/Luau/ConstraintSolver.h | 5 +- Analysis/include/Luau/Set.h | 7 + Analysis/include/Luau/Subtyping.h | 8 -

This meant that there was no link back to the `AstLocal` that defines the prefix variable, making operations like rename refactoring more difficult: renaming the `Types` local would require it's own scope-aware mechanism to figure out the right `AstLocal`, and would not account for issues such as shadowing. This PR introduces an `AstLocal* prefixLocal` field to AstTypeReference that tracks this data, mirroring how AstExprLocal links expression references back to their local definitions. We keep the `AstName` because it is still syntactically valid to have a Luau file that references a prefix that does not exist (e.g., `Unknown.Foo`). Given there is no AstLocal for `Unknown`, we still need to track the name to support type error analysis and pretty-print roundtripping. This change is (partially) gated behind the FFlag `LuauTrackPrefixLocal`. Given the change to the AstTypeReference constructor, this change is technically unflagged.

This results in hosts [re-implementing the function](https://sleitnick.github.io/luau-api/guides/tags.html#:~:text=interrogating%20the%20tag) on their side, observable in Luau's own tests and Type Function Runtime. Adds flag `LuauUdtfTypeUseTaggedMetatable`. Error messages will say e.g. `expected userdata, got x` instead of `expected type, got x` unless a metatable with `__type` is attached to the tag. Went through uses of `lua_touserdatatagged` to switch them to this function when intent is the same. Also adds `lua_getuserdataname` as a dependency to continue to ensure that all `lualib.h` helpers only use public C APIs. --------- Co-authored-by: vegorov-rbx <75688451+vegorov-rbx@users.noreply.github.com> --- Analysis/src/TypeFunctionRuntime.cpp | 52 ++++++++++++++++++---------- VM/include/lua.h | 3 ++ VM/include/lualib.h | 1 + VM/src/lapi.cpp | 16 +++++++++ VM/src/laux.cpp | 10 ++++++ tests/Conformance.test.cpp | 24 ++++++------- 6 files changed, 74 insertions(+), 32 deletions(-) diff --git a/Analysis/src/TypeFunctionRuntime.cpp b/Analysis/src/TypeFunctionRuntime.cpp index df3d1122..33885307 100644 --- a/Analysis/src/TypeFunctionRuntime.cpp +++ b/Analysis/src/TypeFunctionRuntime.cpp @@ -32,6 +32,7 @@ LUAU_FASTFLAGVARIABLE(LuauTypeFunctionRobustness) LUAU_FASTFLAGVARIABLE(LuauUdtfTypeIsSubtypeOf) LUAU_FASTFLAGVARIABLE(LuauTypeFunctionTableIndexerIsReadOnly) LUAU_FASTFLAGVARIABLE(LuauUdtfCreateSingletonFixErrorMessage) +LUAU_FASTFLAGVARIABLE(LuauUdtfTypeUseTaggedMetatable) namespace Luau { @@ -339,12 +340,20 @@ void pushType(lua_State* L, TypeFunctionTypeId type) { luaL_checkstack(L, 2, "allocating type");

We hope for this to entirely replace `DenseHash` as, for our workloads, it is as-good or better than `DenseHash`, supports erasing elements, _and_ does not require elements to be default constructible, meaning some uses of `std::unordered_map` can now be `DenseHashMap`. # Analysis * Fixed inference of higher order generic functions when, themselves, used with generic functions: ```luau local function identity(t: T) return t end -- Prior, `result` is of type `T?` and we error on `42` claiming its not of type `T`. -- Now there are no errors and `result` is of type `number?` local ok, result = pcall(identity, 42) ``` * Fixed a class of internal compiler errors that could occur when nesting type-state-ing functions: ```luau local tbl = {} -- In some cases we would throw an exception like "CG: AstExprLocal came before its declaration?" setmetatable(tbl, setmetatable(tbl, {})) ``` * Indexing into refinements against `any` should now preserve the any-ness of the original value: ```luau -- Prior the first two return statements would raise a type -- checking error, as we'd claim they were `~nil`, dropping -- the `*error-type*` part. local function keyExtractor(item: any, index: number): string if typeof(item) == "table" and item.key ~= nil then return item.key end if typeof(item) == "table" and item.id ~= nil then return item.id end return tostring(index) end ``` # Runtime * Fixed a garbage collection issue with `lua_registeruserdatadirectfieldget`, where depending on the GC phase, we may erroneously consider an allocated dispatch table to be unreachable. * NCG: When replacing an instruction, we now more consistently attempt to substitute it with a precomputed value. E.g., if we replace an IR instruction with one that has already been computed, we can potentially emit a `STORE` rather than said instruction _and_ an additional `STORE`. --------- Co-authored-by: Andy Friesen Co-authored-by: Annie Tang Co-authored-by: Hunter Goldstein Co-authored-by: Ilya Rezvov Co-authored-by: Thomas Schollenberger Co-authored-by: Varun Saini Co-authored-by: Vighnesh Vijay Co-authored-by: Vyacheslav Egorov --- Analysis/include/Luau/Instantiation2.h | 17 +- Analysis/include/Luau/TypePack.h | 4 + Analysis/src/AutocompleteCore.cpp | 3 +- Analysis/src/ConstraintSolver.cpp | 9 +- Analysis/src/DataFlowGraph.cpp | 52 +- Analysis/src/Instantiation2.cpp | 105 ++- Analysis/src/TypeFunctionRuntime.cpp | 79 +- Analysis/src/TypePack.cpp | 8 + Analysis/src/Unifier2.cpp | 129 ++- Analysis/src/UserDefinedTypeFunction.cpp | 55 +- Bytecode/include/Luau/BytecodeBuilder.h | 4 +- Bytecode/include/Luau/Sccp.h | 200 +++++ Bytecode/src/BytecodeBuilder.cpp | 20 +- Bytecode/src/BytecodeGraph.cpp | 20 + Bytecode/src/Sccp.cpp | 247 ++++++ CodeGen/include/Luau/AssemblyBuilderA64.h | 9 +- CodeGen/include/Luau/AssemblyBuilderX64.h | 10 +- CodeGen/include/Luau/LogBuilder.h | 44 ++ CodeGen/src/AssemblyBuilderA64.cpp | 251 ++++-- CodeGen/src/AssemblyBuilderX64.cpp | 99 ++- CodeGen/src/CodeGenA64.cpp | 33 +- CodeGen/src/CodeGenA64.h | 3 +- CodeGen/src/CodeGenAssembly.cpp | 239 ++++-- CodeGen/src/CodeGenContext.cpp | 13 +- CodeGen/src/CodeGenLower.h | 80 +- CodeGen/src/CodeGenX64.cpp | 29 +- CodeGen/src/CodeGenX64.h | 3 +- CodeGen/src/IrAnalysis.cpp | 52 +- CodeGen/src/IrDump.cpp | 49 +- CodeGen/src/IrLoweringA64.cpp | 68 +- CodeGen/src/IrLoweringA64.h | 3 +- CodeGen/src/IrLoweringX64.cpp | 296 +++---- CodeGen/src/IrLoweringX64.h | 3 +- CodeGen/src/IrRegAllocA64.cpp | 9 +- CodeGen/src/IrRegAllocX64.cpp | 6 +- CodeGen/src/IrUtils.cpp | 17 +- CodeGen/src/OptimizeConstProp.cpp | 249 ++++-- CodeGen/src/OptimizeDeadStore.cpp | 84 +- CodeGen/src/OptimizeFinalX64.cpp | 4 +- Common/include/Luau/Bytecode.h | 3 +- Common/include/Luau/DenseHash2.h | 911 ++++++++++++++++++++++ Common/include/Luau/HashUtil.h | 14 +- Compiler/src/Compiler.cpp | 8 +- Compiler/src/Types.cpp | 65 +- Inliner/src/JitInliner.cpp | 74 +- Sources.cmake | 3 + VM/src/ldo.cpp | 21 +- VM/src/lfunc.cpp | 3 +- VM/src/lgc.cpp | 17 +- VM/src/lobject.h | 1 + VM/src/lvmexecute.cpp | 2 +- VM/src/lvmload.cpp | 18 +- tests/AssemblyBuilderA64.test.cpp | 9 +- tests/AssemblyBuilderX64.test.cpp | 24 +- tests/Autocomplete.test.cpp | 22 +- tests/CodeAllocator.test.cpp | 16 +- tests/Compiler.test.cpp | 3 - tests/Conformance.test.cpp | 4 - tests/DenseHash2.test.cpp | 503 ++++++++++++ tests/FragmentAutocomplete.test.cpp | 7 - tests/IrAssembly.test.cpp | 2 - tests/IrBuilder.test.cpp | 234 +++++- tests/IrCallWrapperX64.test.cpp | 8 +- tests/IrLowering.test.cpp | 51 -- tests/IrRegAllocX64.test.cpp | 8 +- tests/ToString.test.cpp | 2 - tests/TypeFunction.user.test.cpp | 8 - tests/TypeInfer.aliases.test.cpp | 14 - tests/TypeInfer.anyerror.test.cpp | 32 +- tests/TypeInfer.builtins.test.cpp | 2 - tests/TypeInfer.functions.test.cpp | 27 +- tests/TypeInfer.operators.test.cpp | 3 - tests/TypeInfer.provisional.test.cpp | 2 - tests/TypeInfer.refinements.test.cpp | 25 +- tests/TypeInfer.singletons.test.cpp | 2 - tests/TypeInfer.tables.test.cpp | 7 - tests/TypeInfer.test.cpp | 2 - tests/TypeInfer.tryUnify.test.cpp | 3 - tests/TypeInfer.typestates.test.cpp | 95 ++- tests/TypeInfer.unionTypes.test.cpp | 7 - tests/TypePath.test.cpp | 2 - 81 files changed, 3785 insertions(+), 1084 deletions(-) create mode 100644 Bytecode/include/Luau/Sccp.h create mode 100644 Bytecode/src/Sccp.cpp create mode 100644 CodeGen/include/Luau/LogBuilder.h create mode 100644 Common/include/Luau/DenseHash2.h create mode 100644 tests/DenseHash2.test.cpp diff --git a/Analysis/include/Luau/Instantiation2.h b/Analysis/include/Luau/Instantiation2.h index 9b97ffc8..2e0e6d51 100644 --- a/Analysis/include/Luau/Instantiation2.h +++ b/Analysis/include/Luau/Instantiation2.h @@ -84,7 +84,7 @@ struct Replacer : Substitution }; // A substitution which replaces generic functions by monomorphic functions -struct Instantiation2 final : Substitution +struct Instantiation2_DEPRECATED final : Substitution { // Mapping from generic types to free types to be used in instantiation.

Training proceeds by gradient descent on a loss function, propagating error signals backward through the network to update connection weights." + +sample_texts[13] = "The Amazon rainforest, spanning approximately five and a half million square kilometers across nine countries in South America, represents the largest and most biodiverse tropical rainforest on Earth. It contains roughly ten percent of all known species, including many that remain undiscovered by science. The forest plays a crucial role in regulating the global climate through its massive carbon absorption capacity and its influence on atmospheric moisture patterns. Deforestation threatens not only the incredible biodiversity within the forest but also the stability of regional and global climate systems." + +sample_texts[14] = "Quantum computing exploits phenomena of quantum mechanics, such as superposition and entanglement, to perform computations that would be intractable for classical computers. A quantum bit, or qubit, can exist in a superposition of the zero and one states simultaneously, enabling quantum computers to explore many possible solutions in parallel. However, quantum states are extremely fragile, and maintaining coherence long enough to complete useful computations remains one of the greatest engineering challenges in the field. Current quantum computers are limited by noise and decoherence to relatively short computation sequences." + +sample_texts[15] = "The theory of plate tectonics provides a unifying framework for understanding the dynamic behavior of the Earth's lithosphere. The outer shell of the Earth is divided into several large tectonic plates that float atop the partially molten asthenosphere below. These plates move relative to one another at rates of a few centimeters per year, driven by convection currents in the mantle. At convergent boundaries, one plate may be subducted beneath another, generating volcanic arcs and deep ocean trenches. At divergent boundaries, new crust is created as magma rises to fill the gap between separating plates." + +sample_texts[16] = "The Renaissance period in European history, spanning roughly from the fourteenth to the seventeenth century, marked a profound cultural transformation characterized by renewed interest in classical learning, artistic innovation, and scientific inquiry. Beginning in the Italian city-states and gradually spreading throughout Europe, the Renaissance produced extraordinary achievements in painting, sculpture, architecture, literature, philosophy, and natural science. Figures such as Leonardo da Vinci, Michelangelo, Galileo Galilei, and William Shakespeare exemplify the remarkable breadth of human creativity that flourished during this remarkable period." + +sample_texts[17] = "Distributed computing systems face fundamental challenges related to consistency, availability, and partition tolerance. The CAP theorem, formulated by Eric Brewer and later proven by Seth Gilbert and Nancy Lynch, establishes that in the presence of network partitions, a distributed system cannot simultaneously guarantee both consistency and availability. This impossibility result has profound implications for the design of large-scale distributed databases and web services, forcing architects to make explicit trade-offs based on the specific requirements of their applications." + +sample_texts[18] = "The human visual system is a remarkable biological apparatus capable of detecting electromagnetic radiation in the visible spectrum and constructing detailed three-dimensional representations of the external world. Light enters the eye through the cornea and lens, which focus it onto the retina at the back of the eye. The retina contains approximately one hundred twenty million rod cells for scotopic vision and six million cone cells for photopic and color vision. Neural processing begins in the retina itself, where several layers of neurons perform initial feature extraction before transmitting signals along the optic nerve to the visual cortex." + +sample_texts[19] = "Algorithmic complexity theory provides a rigorous mathematical framework for classifying computational problems according to the resources required to solve them. The class P contains problems solvable in polynomial time by a deterministic Turing machine, while NP contains those verifiable in polynomial time. The famous P versus NP question, one of the Clay Mathematics Institute's Millennium Prize Problems, asks whether every problem whose solution can be efficiently verified can also be efficiently solved. Most computer scientists conjecture that P does not equal NP, implying that many important optimization and decision problems are inherently intractable." + +sample_texts[20] = "Musical composition involves the creative organization of sound elements including pitch, rhythm, timbre, and dynamics into coherent artistic structures. Western classical music developed a sophisticated theoretical framework encompassing scales, modes, harmony, counterpoint, and musical form.

Composers draw upon this theoretical foundation while exercising creative intuition to produce works that engage listeners emotionally and intellectually across diverse cultural contexts and historical periods." + + +sample_texts[21] = "The mitochondrion is a membrane-bound organelle found in the cytoplasm of eukaryotic cells. It generates most of the cell's supply of adenosine triphosphate, the molecule used as a source of chemical energy to power the metabolic processes of the cell. In addition to supplying cellular energy, mitochondria are involved in other tasks such as signaling, cellular differentiation, cell death, and the control of the cell cycle and cell growth. A striking characteristic is that mitochondria contain their own DNA, a remnant of their origin as independent prokaryotic organisms that were engulfed by ancestral eukaryotic cells in a process called endosymbiosis." + +sample_texts[22] = "The quantum mechanical model of the atom replaced the earlier Bohr planetary model by treating electrons not as particles orbiting a nucleus along well-defined trajectories, but rather as probability clouds described by complex-valued wave functions. The Schrodinger equation, first formulated in 1926, provides the mathematical framework for computing these probability distributions. Each electron is characterized by four quantum numbers: the principal quantum number n, the azimuthal quantum number l, the magnetic quantum number m, and the spin quantum number s. The Pauli exclusion principle states that no two electrons in an atom can share the same set of all four quantum numbers simultaneously." + +sample_texts[23] = "It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair. We had everything before us, we had nothing before us, we were all going direct to Heaven, we were all going direct the other way.

A graph consists of vertices connected by edges, and may be directed or undirected, weighted or unweighted. Classical problems in graph theory include finding shortest paths, computing maximum flows, determining graph coloring, and identifying minimum spanning trees. Many of these problems have efficient polynomial-time algorithms, while others, such as finding the largest clique or determining Hamiltonicity, are NP-complete and believed to require exponential time in the worst case." + +sample_texts[25] = "The global carbon cycle describes the movement of carbon atoms between the atmosphere, oceans, terrestrial biosphere, and geosphere. Photosynthesis removes carbon dioxide from the atmosphere and converts it into organic compounds, while respiration and decomposition return carbon to the atmosphere. The oceans serve as a massive carbon sink, absorbing approximately one quarter of anthropogenic carbon dioxide emissions. Geological processes operate on much longer timescales, with carbon being sequestered in sedimentary rocks and fossil fuels over millions of years. Human activities, particularly the combustion of fossil fuels and deforestation, have significantly perturbed this natural cycle." + +sample_texts[26] = "Cryptographic hash functions are deterministic algorithms that map arbitrary-length input data to fixed-length output values, satisfying several critical security properties. First, they must be computationally efficient to evaluate. Second, they must be preimage resistant, meaning that given a hash value, it should be infeasible to find any input that produces that value. Third, they must be collision resistant, meaning that it should be infeasible to find two distinct inputs that produce the same hash value. These properties make hash functions indispensable in digital signatures, message authentication codes, password storage, and blockchain consensus mechanisms." + +sample_texts[27] = "The symphony orchestra as we know it today evolved gradually over several centuries, from the small ensembles of the Baroque period to the massive forces employed by late Romantic composers. The modern symphony orchestra typically comprises four sections: strings, woodwinds, brass, and percussion. The string section, forming the backbone of orchestral sound, includes first and second violins, violas, cellos, and double basses. Woodwinds add color and melodic variety with flutes, oboes, clarinets, and bassoons. Brass instruments provide power and brilliance through trumpets, horns, trombones, and tubas." + +sample_texts[28] = "Operating system kernels mediate between application software and computer hardware, providing essential services including process management, memory allocation, device driver interfaces, and filesystem operations. Modern kernels employ sophisticated scheduling algorithms to share processor time among competing processes, using priorities, time slices, and various heuristics to balance responsiveness and throughput. Virtual memory systems create the illusion of a large, contiguous address space for each process while managing the actual physical memory as a shared resource. Security and isolation between processes are enforced through hardware-supported privilege levels and memory protection mechanisms." + +sample_texts[29] = "The theory of evolution by natural selection, first articulated comprehensively by Charles Darwin and Alfred Russel Wallace in the mid-nineteenth century, provides the unifying framework for modern biology. Organisms exhibit heritable variation in traits that affect their survival and reproductive success. Those individuals better adapted to their environment tend to leave more offspring, causing beneficial traits to become more prevalent in subsequent generations. Over vast spans of geological time, this process has generated the extraordinary diversity of life on Earth, from single-celled microorganisms to complex multicellular organisms occupying every conceivable ecological niche." + +sample_texts[30] = "Compiler optimization passes transform intermediate representations of programs to produce more efficient machine code without altering the observable behavior of the program. Common optimizations include dead code elimination, which removes instructions whose results are never used; constant propagation, which replaces variables with their known constant values; loop-invariant code motion, which hoists computations out of loops when their values do not change between iterations; and instruction scheduling, which reorders operations to minimize pipeline stalls and maximize instruction-level parallelism on modern processors." + +sample_texts[31] = "The deep ocean remains one of the least explored environments on Earth, with vast regions of the abyssal plains and hadal trenches still unmapped and unstudied. Despite extreme conditions including crushing pressure, near-freezing temperatures, and complete absence of sunlight, these environments support diverse communities of organisms adapted to their unique circumstances. Chemosynthetic bacteria near hydrothermal vents form the base of food webs entirely independent of solar energy, fundamentally challenging previous assumptions about the requirements for life." + +sample_texts[32] = "Information theory, founded by Claude Shannon in his seminal 1948 paper, provides the mathematical framework for quantifying information content and the fundamental limits of data compression and reliable communication over noisy channels. Shannon entropy measures the average information content of a random variable, while mutual information quantifies the dependency between two variables. The channel coding theorem establishes that reliable communication is possible at any rate below the channel capacity, and that no scheme can reliably communicate above this rate. These results have profoundly influenced telecommunications, data storage, and statistical inference." + +sample_texts[33] = "Protein folding is the physical process by which a polypeptide chain, synthesized as a linear sequence of amino acids by the ribosome, acquires its characteristic three-dimensional structure. The native fold is determined primarily by the amino acid sequence and is stabilized by numerous weak interactions including hydrogen bonds, van der Waals forces, electrostatic interactions, and hydrophobic effects. Understanding and predicting protein structure from sequence remains one of the grand challenges of molecular biology, as the number of possible conformations grows exponentially with chain length." + +sample_texts[34] = "The printing press revolutionized the dissemination of knowledge throughout Europe and eventually the world. Before Gutenberg's innovation, books were produced by hand in monastic scriptoria, making them extremely expensive and accessible only to the wealthy and the clergy.

charset=UTF-8 Content-Transfer-Encoding: 8bit Happy end of July! In accordance with Zeus's law, the Luau team is bringing forth another exciting release! 🌩️⚡️ ## General * Added the ability to parse config files from bytecode rather than source! * Fixups for `DenseHash2` * More optimizations for the `export` keyword * More internal refactoring and development to support cyclic module dependencies for exported modules ## Analysis * Zero-argument type functions no longer break when exported, resolving https://github.com/luau-lang/luau/issues/2554 * Enable type function evaluation in fragment autocomplete, so: ```lua type function test(ty: type) return types.unionof(types.singleton('test'), types.singleton('test2')) end local a: test = 'test' -- autocomplete now shows up when adding quotes or filling the word "test" in ``` ## Runtime * Add bytecode version for double-precision vector constants + options fix * Switch Luau C Closure debugname from `const char*` to `TString*` * Luau NCG: fixed an issue where linear code blocks generated unreachable code * Luau NCG: improved spill restore location hints which should reduce spill slot pressure * Luau NCG: improved unnecessary tag check removal optimization * Fixed https://github.com/luau-lang/luau/issues/1893 --------------------------------- And, as always, thanks to all our contributors!
