For example, files, threads, GPU resources and objects\r\nwith large external allocations.\r\n\r\nWith Lua, a finalizer can be _generically_ called by invoking the __gc\r\nmetamethod manually, but this is currently not possible with tagged\r\nuserdata in Luau because it's not possible to query the destructor\r\nassociated with an userdata. While it is possible to workaround this by\r\nduplicating the destructor table locally on client side (*), it's more\r\nconvenient to deduplicate the data and get the destructor using the API\r\ninstead.\r\n\r\n(*) Note: a separate destructor table for each VM may be required if the\r\nVMs use different set of tags.\r\n\r\nImplementation notes:\r\n\r\n1. I first considered adding a typedef for lua_Destructor but\r\nunfortunately there are two kinds of destructors, one with and one\r\nwithout the lua_State* argument, so I decided against it at this point.\r\nMaybe it should be added later if the destructor API is unified (by\r\ndropping the Lua state pointer argument?).\r\n\r\n2. For some reason the conformance test produced warning \"qualifier\r\napplied to function type has no meaning; ignored\" on VS2017 (possibly\r\nbecause the test framework does not like function pointers for some\r\nreason?).

Previously,\r\nbreakpoints might have been skipped in `else` blocks at the end of a\r\nfunction\r\n* Fixed how unification is performed for two optional types `a? <: b?`,\r\npreviously it might have unified either 'a' or 'b' with 'nil'. Note that\r\nthis fix is not enabled by default yet (see the list in\r\n`ExperimentalFlags.h`)\r\n\r\nIn the new type solver, a concept of 'Type Families' has been\r\nintroduced.\r\nType families can be thought of as type aliases with custom type\r\ninference/reduction logic included with them.\r\nFor example, we can have an `Add<T, U>` type family that will resolve\r\nthe type that is the result of adding two values together.\r\nThis will help type inference to figure out what 'T' and 'U' might be\r\nwhen explicit type annotations are not provided.\r\nIn this update we don't define any type families, but they will be added\r\nin the near future.\r\nIt is also possible for Luau embedders to define their own type families\r\nin the global/environment scope.\r\n\r\nOther changes include:\r\n* Fixed scope used to find out which generic types should be included in\r\nthe function generic type list\r\n* Fixed a crash after cyclic bound types were created during unification\r\n\r\nAnd in native code generation (jit):\r\n* Use of arm64 target on M1 now requires macOS 13\r\n* Entry into native code has been optimized. This is especially\r\nimportant for coroutine call/pcall performance as they involve going\r\nthrough a C call frame\r\n* LOP_LOADK(X) translation into IR has been improved to enable type\r\ntag/constant propagation\r\n* arm64 can use integer immediate values to synthesize floating-point\r\nvalues\r\n* x64 assembler removes duplicate 64bit numbers from the data section to\r\nsave space\r\n* Linux `perf` can now be used to profile native Luau code (when running\r\nwith --codegen-perf CLI argument)",

We\r\nshouldn't be creating cyclic unions, but we shouldn't be crashing when\r\nthey arise either.\r\n* Minor cleanup of `luau_precall`\r\n* Internal change to make L->top handling slightly more uniform\r\n* Optimize SETGLOBAL & GETGLOBAL fallback C functions.\r\n* https://github.com/Roblox/luau/pull/929\r\n* The syntax to the `luau-reduce` commandline tool has changed. It now\r\naccepts a script, a command to execute, and an error to search for. It\r\nno longer automatically passes the script to the command which makes it\r\na lot more flexible. Also be warned that it edits the script it is\r\npassed **in place**. Do not point it at something that is not in source\r\ncontrol!\r\n\r\nNew solver\r\n\r\n* Switch to a greedier but more fallible algorithm for simplifying union\r\nand intersection types that are created as part of refinement\r\ncalculation. This has much better and more predictable performance.\r\n* Fix a constraint cycle in recursive function calls.\r\n* Much improved inference of binary addition. Functions like `function\r\nadd(x, y) return x + y end` can now be inferred without annotations. We\r\nalso accurately typecheck calls to functions like this.\r\n* Many small bugfixes surrounding things like table indexers\r\n* Add support for indexers on class types. This was previously added to\r\nthe old solver; we now add it to the new one for feature parity.\r\n\r\nJIT\r\n\r\n* https://github.com/Roblox/luau/pull/931\r\n* Fuse key.value and key.tt loads for CEHCK_SLOT_MATCH in A64\r\n* Implement remaining aliases of BFM for A64\r\n* Implement new callinfo flag for A64\r\n* Add instruction simplification for int->num->int conversion chains\r\n* Don't even load execdata for X64 calls\r\n* Treat opcode fallbacks the same as manually written fallbacks\r\n\r\n---------\r\n\r\nCo-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com>\r\nCo-authored-by: Vyacheslav Egorov <vegorov@roblox.com>",

This was\r\ncausing a crash in certain situations.\r\n* Luau heap graph enumeration improvements:\r\n    * Weak references are not reported\r\n    * Added tag as a fallback name of non-string table links\r\n* Included top Luau function information in thread name to understand\r\nwhere thread might be suspended\r\n* Constant folding for `math.pi` and `math.huge` at -O2\r\n* Optimize `string.format` and `%*`\r\n* This change makes string interpolation 1.5x-2x faster depending on the\r\nnumber and type of formatted components, assuming a few are using\r\nprimitive types, and reduces associated GC pressure.\r\n\r\nNew type checker:\r\n\r\n* Initial work toward tracking the upper and lower bounds of types\r\naccurately.\r\n\r\nNative code generation (JIT):\r\n\r\n* Add IrCmd::CHECK_TRUTHY for improved assert fast-calls\r\n* Do not compute type map for modules without types\r\n* Capture metatable+readonly state for NEW_TABLE IR instructions\r\n* Replace JUMP_CMP_ANY with CMP_ANY and existing JUMP_EQ_INT\r\n* Add support for exits to VM with reentry lock in VmExit\r\n\r\n---------\r\n\r\nCo-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com>\r\nCo-authored-by: Vyacheslav Egorov <vegorov@roblox.com>",

It is now `<A..., R...>(f:\r\n(A...) -> R...) -> ((A...) -> R...)`\r\n* Break `.luaurc` out into a separate library target `Luau.Config`. This\r\nmakes it easier for applications to reason about config files without\r\nalso depending on the type inference engine.\r\n* Move typechecking limits into `FrontendOptions`. This allows embedders\r\nmore finely-grained control over autocomplete's internal time limits.\r\n* Fix stability issue with debugger onprotectederror callback allowing\r\nbreak in non-yieldable contexts\r\n\r\nNew solver:\r\n\r\n* Initial work toward [Local Type\r\nInference](https://github.com/Roblox/luau/blob/0e1082108fd6fb3a32dfdf5f1766ea3fc1391328/rfcs/local-type-inference.md)\r\n* Introduce a new subtyping test. This will be much nicer than the old\r\ntest because it is completely separate both from actual type inference\r\nand from error reporting.\r\n\r\nNative code generation:\r\n\r\n* Added function to compute iterated dominance frontier\r\n* Optimize barriers in SET_UPVALUE when tag is known\r\n* Cache lua_State::global in a register on A64\r\n* Optimize constant stores in A64 lowering\r\n* Track table array size state to optimize array size checks\r\n* Add split tag/value store into a VM register\r\n* Check that spills can outlive the block only in specific conditions\r\n\r\n---------\r\n\r\nCo-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com>\r\nCo-authored-by: Vyacheslav Egorov <vegorov@roblox.com>",

          "message": "Add tagged lightuserdata (#1087)\n\nThis change adds support for tagged lightuserdata and optional custom\r\ntypenames for lightuserdata.\r\n\r\nBackground: Lightuserdata is an efficient representation for many kinds\r\nof unmanaged handles and resources in a game engine. However, currently\r\nthe VM only supports one kind of lightuserdata, which makes it\r\nproblematic in practice. For example, it's not possible to distinguish\r\nbetween different kinds of lightuserdata in Lua bindings, which can lead\r\nto unsafe practices and even crashes when a wrong kind of lightuserdata\r\nis passed to a binding function. Tagged lightuserdata work similarly to\r\ntagged userdata, i.e. they allow checking the tag quickly using\r\nlua_tolightuserdatatagged (or lua_lightuserdatatag).\r\n\r\nThe tag is stored in the 'extra' field of TValue so it will add no cost\r\nto the (untagged) lightuserdata type.\r\n\r\nAlternatives would be to use full userdata values or use bitpacking to\r\nembed type information into lightuserdata on application level.\r\nUnfortunately these options are not that great in practice: full\r\nuserdata have major performance implications and bitpacking fails in\r\ncases where full 64 bits are already used (e.g. pointers or 64-bit\r\nhashes).\r\n\r\nLightuserdata names are not strictly necessary but they are rather\r\nconvenient when debugging Lua code. More precise error messages and\r\ntostring returning more specific typename are useful to have in practice\r\n(e.g. \"resource\" or \"entity\" instead of the more generic \"userdata\").\r\n\r\nImpl note: I did not add support for renaming tags in\r\nlua_setlightuserdataname as I'm not sure if it's possible to free fixed\r\nstrings. If it's simple enough, maybe we should allow renaming (although\r\nI can't think of a specific need for it)?\r\n\r\n---------\r\n\r\nCo-authored-by: Petri Häkkinen <petrih@rmd.remedy.fi>",

          "message": "Improve A64 lowering for vector operations by using vector instructions (#1164)\n\nThis change replaces scalar versions of vector opcodes for A64 with\r\nactual vector instructions.\r\n\r\nWe take the approach similar to X64: patch last component with zero,\r\nperform the math, patch last component with type tag. I'm hoping that in\r\nthe future the type tag will be placed separately (separate IR opcode?)\r\nbecause right now chains of math operations result in excessive type tag\r\noperations.\r\n\r\nTo patch the type tag without always keeping a mask in a register,\r\nins.4s instructions can be used; unfortunately it's only capable of\r\npatching a register in-place, so we need an extra register copy in case\r\nit's not last-use. Usually it's last-use so the patch is free; probably\r\nwith IR rework mentioned above all of this can be improved (e.g.\r\nload-with-patch will never need to copy).\r\n\r\n~It's not 100% clear if we *have* to patch type tag: Apple does preserve\r\ndenormals but we'd need to benchmark this to see if there's an actual\r\nperformance impact. But for now we're playing it safe.~\r\n\r\nThis was tested by running the conformance tests, and new opcode\r\nimplementations were checked by comparing the result with\r\nhttps://armconverter.com/.\r\n\r\nPerformance testing is complicated by the fact that OSS Luau doesn't\r\nsupport vector constructor out of the box, and other limitations of\r\ncodegen. I've hacked vector constructor/type into REPL and confirmed\r\nthat on a test that calls this function in a loop (not inlined):\r\n\r\n```\r\nfunction fma(a: vector, b: vector, c: vector)\r\n        return a * b + c\r\nend\r\n```\r\n\r\n... this PR improves performance by ~6% (note that probably most of the\r\noverhead here is the call dispatch; I didn't want to brave testing a\r\nmore complex expression).

This reduces implementation redundancy, but more importantly\r\nallows for a class of optimizations:\r\n\r\n- NUM_TO_VECTOR previously patched the component unconditionally but the\r\nresult was used only in MUL/DIV_VEC instructions that ignore it anyway;\r\nwe can now remove this.\r\n\r\n- ADD_VEC et al can now forward the source of TAG_VECTOR instruction of\r\neither input; this shortens the latency chain and in the future could\r\nallow us to generate optimal vector instruction sequence once the\r\ntemporary stores are marked as dead.\r\n\r\n- In the future on X64, ADD_VEC et al will be able to analyze the input\r\ninstruction and remove tag masking conditionally. This is not part of\r\nthis PR as it requires a decision around expected FP environment and/or\r\nthe necessity of the existing masking to begin with.\r\n\r\nI've also renamed NUM_TO_VECTOR to NUM_TO_VEC so that \"VEC\" always\r\nrefers to \"3 float values\" and for consistency with ADD/etc.\r\n\r\nNote: ADD_VEC input forwarding is currently performed unconditionally;\r\nit may or may not increase the spills that can't be reloaded from the\r\nstack.\r\n\r\nOn A64 this makes the Taylor series computation a tiny bit faster\r\n(11.3ns => 11.0ns) as it removes the redundant ins instructions along\r\nthe NUM_TO_VEC path. Curiously, the optimization of forwarding\r\nTAG_VECTOR input to arithmetic instructions actually has a small penalty\r\nas without it this PR runs at 10.9 ns. I don't know if this is a\r\nproperty of the benchmark though, as I just noticed that in this\r\nbenchmark type inference actually fails to infer parts of the\r\ncomputation as a vector op. If desired I will happily omit this part of\r\nthe change and we can explore that separately.",

          "message": "CodeGen: Improve lowering of NUM_TO_VEC on A64 for constants (#1194)\n\nWhen the input is a constant, we use a fairly inefficient sequence of\r\nfmov+fcvt+dup or, when the double isn't encodable in fmov,\r\nadr+ldr+fcvt+dup.\r\n\r\nInstead, we can use the same lowering as X64 when the input is a\r\nconstant, and load the vector from memory. However, if the constant is\r\nencodable via fmov, we can use a vector fmov instead (which is just one\r\ninstruction and doesn't need constant space).\r\n\r\nFortunately the bit encoding of fmov for 32-bit floating point numbers\r\nmatches that of 64-bit: the decoding algorithm is a little different\r\nbecause it expands into a larger exponent, but the values are\r\ncompatible, so if a double can be encoded into a scalar fmov with a\r\ngiven abcdefgh pattern, the same pattern should encode the same float;\r\ndue to the very limited number of mantissa and exponent bits, all values\r\nthat are encodable are also exact in both 32-bit and 64-bit floats.\r\n\r\nThis strategy is ~same as what gcc uses. For complex vectors, we\r\npreviously used 4 instructions and 8 bytes of constant storage, and now\r\nwe use 2 instructions and 16 bytes of constant storage, so the memory\r\nfootprint is the same; for simple vectors we just need 1 instruction (4\r\nbytes).\r\n\r\nclang lowers vector constants a little differently, opting to synthesize\r\na 64-bit integer using 4 instructions (mov/movk) and then move it to the\r\nvector register - this requires 5 instructions and 20 bytes, vs ours/gcc\r\n2 instructions and 8+16=24 bytes. I tried a simpler version of this that\r\nwould be more compact - synthesize a 32-bit integer constant with\r\nmov+movk, and move it to vector register via dup.4s - but this was a\r\nlittle slower on M2, so for now we prefer the slightly larger version as\r\nit's not a regression vs current implementation.\r\n\r\nOn the vector approximation benchmark we get:\r\n\r\n- Before this PR (flag=false): ~7.85 ns/op\r\n- After this PR (flag=true): ~7.74 ns/op\r\n- After this PR, with 0.125 instead of 0.123 in the benchmark code (to\r\nuse fmov): ~7.52 ns/op\r\n- Not part of this PR, but the mov/dup strategy described above: ~8.00\r\nns/op",

          "message": "CodeGen: Preserve known tags for LOAD_TVALUE synthesized from LOADK (#1201)\n\nWhen lowering LOADK for booleans/numbers/nils, we deconstruct the\r\noperation using STORE_TAG which informs the rest of the optimization\r\npipeline about the tag of the value. This is helpful to remove various\r\ntag checks.\r\n\r\nWhen the constant is a string or a vector, we just use\r\nLOAD_TVALUE/STORE_TVALUE. For strings, this could be replaced by pointer\r\nload/store, but for vectors there's no great alternative using current\r\nIR ops; in either case, the optimization needs to be carefully examined\r\nfor profitability as simply copying constants into registers for\r\nfunction calls could become more expensive.\r\n\r\nHowever, there are cases where it's still valuable to preserve the tag.\r\nFor vectors, doing any math with vector constants contains tag checks\r\nthat could be removed. For both strings and vectors, storing them into a\r\ntable has a barrier that for vectors could be elided, and for strings\r\ncould be simplified as there's no need to confirm the tag.\r\n\r\nWith this change we now carry the optional tag of the value with\r\nLOAD_TVALUE. This has no performance effect on existing benchmarks but\r\ndoes reduce the generated code for benchmarks by ~0.1%, and it makes\r\nvector code more efficient (~5% lift on X64 log1p approximation).",

Note that `table.concat` also supports numbers (these need\r\nto be converted to strings which is a little cumbersome and has innate\r\noverhead), and out-of-bounds accesses*. In these cases we fall back to\r\nthe old implementation.\r\n\r\nTo trigger out-of-bounds accesses, you need to skip the past-array-end\r\nelement (which is nil per array invariant), but this is achievable\r\nbecause table.concat supports offset+length arguments.

For example:\r\n\r\n1. Normalization and simplification cannot handle cyclic types due to\r\nthe nature of their implementation.\r\n2. Normalization can't tell when two tables or functions are equivalent,\r\nbut simplification theoretically can albeit not implemented.\r\n3. Normalization requires deep normalization for inhabitance check,\r\nwhereas simplification would've returned the `never` type itself\r\nindicating uninhabited.\r\n4. Simplification requires constraint ordering to have perfect timing to\r\nsimplify.\r\n5. Adding a rewrite rule requires implementing it twice, once in\r\nsimplification and once again in normalization with completely different\r\ncode design making it hard to verify that their behavior is materially\r\nequivalent.\r\n6. In cases where we must cache for performance, two different types\r\nthat are isomorphic have different cache entries resulting in cache\r\nmisses.\r\n7. Type family reduction can handle cyclic type families, but only if\r\nthe cycle is not obscured by a different type family instance. (`t1\r\nwhere t1 = union<number, add<t1, number>>` is irreducible)\r\n\r\nI think we're getting the point!\r\n\r\n---\r\n\r\nCurrently the implementation is missing a few features that makes\r\ne-graphs actually useful. Those will be coming in a future PR.\r\n\r\n1. Pattern matching,\r\n6. Applying rewrites,\r\n7. Rewrite until saturation, and\r\n8. Extracting the best e-node according to some cost function.",
