* [reference-types] Support passive elem segments (#3572)Abbas Mashayekh2021-03-051-23/+55
| | | | | | | | | | | Passive element segments do not belong to any table, so the link between Table and elem needs to be weaker; i.e. an elem may have a table in case of active segments, or simply be a collection of function references in case of passive/declarative segments. This PR takes Table::Segment out and turns it into a first class module element just like tables and functions. It also implements early support for parsing, printing, encoding and decoding passive/declarative elem segments.

|
* Slightly improve table C API (#3604)Daniel Wirtz2021-02-261-2/+15
| | | Uses BinaryenIndex instead of int to mirror parameter types in table construction, and adds setters for name, initial and max.

* [EH] Make rethrow's target a try label (#3568)Heejin Ahn2021-02-181-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I was previously mistaken about `rethrow`'s argument rule and thought it only counted `catch`'s depth. But it turns out it follows the same rule `delegate`'s label: the immediate argument follows the same rule as when computing branch labels, but it only can target `try` labels (semantically it targets that `try`'s corresponding `catch`); otherwise it will be a validation failure. Unlike `delegate`, `rethrow`'s label denotes not where to rethrow, but which exception to rethrow. For example, ```wasm try $l0 catch ($l0) try $l1 catch ($l1) rethrow $l0 ;; rethrow the exception caught by 'catch ($l0)' end end ``` Refer to this comment for the more detailed informal semantics: https://github.com/WebAssembly/exception-handling/issues/146#issuecomment-777714491 --- This also reverts some of `delegateTarget` -> `exceptionTarget` changes done in #3562 in the validator. Label validation rules apply differently for `delegate` and `rethrow` for try-catch. For example, this is valid: ```wasm try $l0 try delegate $l0 catch ($l0) end ``` But this is NOT valid: ```wasm try $l0 catch ($l0) try delegate $l0 end ``` So `try`'s label should be used within try-catch range (not catch-end range) for `delegate`s. But for the `rethrow` the rule is different. For example, this is valid: ```wasm try $l0 catch ($l0) rethrow $l0 end ``` But this is NOT valid: ```wasm try $l0 rethrow $l0 catch ($l0) end ``` So the `try`'s label should be used within catch-end range instead.
* [EH] Update C and binaryen.js API for delegate (#3565)Heejin Ahn2021-02-131-2/+18
| | | | | | | | | | This updates C and binaryen.js API to match the new `Try` structure to support `delegate`, added in #3561. Now `try` can take a name (which can be null) like a block, and also has an additional `delegateTarget` field argument which should only be used for try-delegate and otherwise null. This also adds several more variant of `makeTry` methods in wasm-builder. Some are for making try-delegate and some are for try-catch(_all).
* finalize: strip segments that contain only EM_ASM/EM_JS data (#3557)Sam Clegg2021-02-121-2/+2
| | | | | | | If we find a data segment whose entire contents is EM_JS or EM_ASM strings then strip it from the binary. See: https://github.com/emscripten-core/emscripten/pull/13443
* [reference-types] remove single table restriction in IR (#3517)Abbas Mashayekh2021-02-091-0/+38
| | | Adds support for modules with multiple tables. Adds a field for the table name to `CallIndirect` and updates the C/JS APIs accordingly.
* [GC] ref.is_func/data/i31 (#3519)Alon Zakai2021-01-261-0/+3
|
* [GC] RefIsNull => RefIs. (#3516)Alon Zakai2021-01-261-5/+7
| | | | | | | | This internal refactoring prepares us for ref.is_func/data/i31, by renaming the node and adding an "op" field. For now that field must always be "Null" which means it is a ref.is_null. This adjusts the C API to match the new IR shape. The high-level JS API is unchanged.
* Reorder i31ref and dataref (#3509)Heejin Ahn2021-01-231-0/+1
| | | | | | | | | | The binary spec (https://docs.google.com/document/d/1yAWU3dbs8kUa_wcnnirDxUu9nEBsNfq0Xo90OWx6yuo/edit#) lists `dataref` after `i31ref`, and `dataref` also comes after `i31ref` in its binary code in the value-increasing order. This reorders these two in wasm-type.h and other places, although in most of those places the order is irrelevant. This also adds C and JS API for `dataref`.
* Remove exnref and br_on_exn (#3505)Heejin Ahn2021-01-221-26/+0
| | | This removes `exnref` type and `br_on_exn` instruction.
* Basic EH instrucion support for the new spec (#3487)Heejin Ahn2021-01-151-15/+63
| | | | | | | | | | | | | | | | | | | | This updates `try`-`catch`-`catch_all` and `rethrow` instructions to match the new spec. `delegate` is not included. Now `Try` contains not a single `catchBody` expression but a vector of catch bodies and events. This updates most existing routines, optimizations, and tests modulo the interpreter and the CFG traversal. Because the interpreter has not been updated yet, the EH spec test is temporarily disabled in check.py. Also, because the CFG traversal for EH is not yet updated, several EH tests in `rse_all-features.wast`, which uses CFG traversal, are temporarily commented out. Also added a few more tests in existing EH test functions in test/passes. In the previous spec, `catch` was catching all exceptions so it was assumed that anything `try` body throws is caught by its `catch`, but now we can assume the same only if there is a `catch_all`. Newly added tests test cases when there is a `catch_all` and cases there are only `catch`es separately.
* Prototype SIMD extending pairwise add instructions (#3466)Thomas Lively2021-01-051-2/+1
| | | | | | As proposed in https://github.com/WebAssembly/simd/pull/380, using the opcodes used in LLVM and V8. Since these opcodes overlap with the opcodes of i64x2.all_true and i64x2.any_true, which have long since been removed from the SIMD proposal, this PR also removes those instructions.
* Improve C and JS API module inspection features (#3464)Daniel Wirtz2021-01-051-10/+31
| | | | | | * BinaryenGetFunction, BinaryenGetGlobal, BinaryenGetEvent now return NULL if an element does not exist * Adds BinaryenGetExport, BinaryenGetNumGlobals, BinaryenGetGlobalByIndex * Corrects BinaryenGetNumFunctions return type * Adds related descriptions of C API functions
* [TypedFunctionReferences] Add Typed Function References feature and use the ↵Alon Zakai2020-11-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | types (#3388) This adds the new feature and starts to use the new types where relevant. We use them even without the feature being enabled, as we don't know the features during wasm loading - but the hope is that given the type is a subtype, it should all work out. In practice, if you print out the internal type you may see a typed function reference-specific type for a ref.func for example, instead of a generic funcref, but it should not affect anything else. This PR does not support non-nullable types, that is, everything is nullable for now. As suggested by @tlively this is simpler for now and leaves nullability for later work (which will apparently require let or something else, and many passes may need to be changed). To allow this PR to work, we need to provide a type on creating a RefFunc. The wasm-builder.h internal API is updated for this, as are the C and JS APIs, which are breaking changes. cc @dcodeIO We must also write and read function types properly. This PR improves collectSignatures to find all the types, and also to sort them by the dependencies between them (as we can't emit X in the binary if it depends on Y, and Y has not been emitted - we need to give Y's index). This sorting ends up changing a few test outputs. InstrumentLocals support for printing function types that are not funcref is disabled for now, until we figure out how to make that work and/or decide if it's important enough to work on. The fuzzer has various fixes to emit valid types for things (mostly whitespace there). Also two drive-by fixes to call makeTrivial where it should be (when we fail to create a specific node, we can't just try to make another node, in theory it could infinitely recurse). Binary writing changes here to replace calls to a standalone function to write out a type with one that is called on the binary writer object itself, which maintains a mapping of type indexes (getFunctionSignatureByIndex).
* Rename atomic.notify and *.atomic.wait (#3353)Heejin Ahn2020-11-131-14/+14
| | | | | | | | | | | | | | - atomic.notify -> memory.atomic.notify - i32.atomic.wait -> memory.atomic.wait32 - i64.atomic.wait -> memory.atomic.wait64 See WebAssembly/threads#149. This renames instruction name printing but not the internal data structure names, such as `AtomicNotify`, which are not always the same as printed instruction names anyway. This also does not modify C API. But this fixes interface functions in binaryen.js because it seems binaryen.js's interface functions all follow the corresponding instruction names.
* Remove some boilerplate in the C API (#3346)Alon Zakai2020-11-121-64/+5
| | | | Also slightly reorder some code in the binary writer headers, that I noticed while looking for boilerplate.
* Remove remaining bits of C API tracing, which has been removed (#3322)Alon Zakai2020-11-051-1/+1
| | | It was removed in #2841
* Prototype new SIMD multiplications (#3291)Thomas Lively2020-10-281-1/+3
| | | | | | | Including saturating, rounding Q15 multiplication as proposed in https://github.com/WebAssembly/simd/pull/365 and extending multiplications as proposed in https://github.com/WebAssembly/simd/pull/376. Since these are just prototypes, skips adding them to the C or JS APIs and the fuzzer, as well as implementing them in the interpreter.
* Implement i8x16.popcnt (#3286)Thomas Lively2020-10-271-0/+1
| | | | | | As proposed in https://github.com/WebAssembly/simd/pull/379. Since this instruction is still being evaluated for inclusion in the SIMD proposal, this PR does not add support for it to the C/JS APIs or to the fuzzer. This PR also performs a drive-by fix for unrelated instructions in c-api-kitchen-sink.c
* Implement v128.{load,store}{8,16,32,64}_lane instructions (#3278)Thomas Lively2020-10-221-0/+1
| | | | | | | These instructions are proposed in https://github.com/WebAssembly/simd/pull/350. This PR implements them throughout Binaryen except in the C/JS APIs and in the fuzzer, where it leaves TODOs instead. Right now these instructions are just being implemented for prototyping so adding them to the APIs isn't critical and they aren't generally available to be fuzzed in Wasm engines.
* Fix Wasm capitalization in binaryen-c.h comments (#3233)Max Desiatov2020-10-131-2/+2
| | | According to the WebAssembly spec, Wasm is an abbreviation, not an acronym.
* Add C and JS APIs for fast math (#3188)Max Graey2020-10-011-0/+10
| | | Adds `BinaryenGetFastMath` and `BinaryenSetFastMath` to the C API, respectively `binaryen.getFastMath` and `binaryen.setFastMath` to the JS API.
* GC: Add stubs for the remaining instructions (#3174)Daniel Wirtz2020-09-291-0/+24
| | | NFC, except adding most of the boilerplate for the remaining GC instructions. Each implementation site is marked with a respective `TODO (gc): theInstruction` in between the typical boilerplate code.
* GC: Add i31 instructions (#3154)Daniel Wirtz2020-09-241-0/+30
| | | Adds the `i31.new` and `i31.get_s/u` instructions for creating and working with `i31ref` typed values. Does not include fuzzer integration just yet because the fuzzer expects that trivial values it creates are suitable in global initializers, which is not the case for trivial `i31ref` expressions.
* Add Memory64 feature flag to the C and JS APIs (#3148)Daniel Wirtz2020-09-211-0/+1
|
* GC: Add ref.eq instruction (#3145)Daniel Wirtz2020-09-211-0/+19
| | | With `eqref` now integrated, the `ref.eq` instruction can be implemented. The only valid LHS and RHS value is `(ref.null eq)` for now, but implementation and fuzzer integration is otherwise complete.
* GC: Integrate eqref and i31ref types (#3141)Daniel Wirtz2020-09-191-0/+2
| | | Adds the `eqref` and `i31ref` types to their respective code locations. Implements what can be implemented trivially and otherwise traps with a TODO for now. Integration of `eqref` is mostly complete due to it being nullable, just like `anyref`, but `i31ref` needs to remain disabled in the fuzzer because we are lacking the functionality to create trivial `i31ref` values, i.e. `(i31.new (i32.const 0))`, which is left for follow-ups to implement.
* Refactor Host expression to MemorySize and MemoryGrow (#3137)Daniel Wirtz2020-09-171-45/+12
| | | Aligns the internal representations of `memory.size` and `memory.grow` with other more recent memory instructions by removing the legacy `Host` expression class and adding separate expression classes for `MemorySize` and `MemoryGrow`. Simplifies related APIs, but is also a breaking API change.
* Add GC feature flag (#3135)Daniel Wirtz2020-09-171-1/+1
| | | Adds the `--enable-gc` feature flag, so far enabling the `anyref` type incl. subtyping, and removes the temporary `--enable-anyref` feature flag that it replaces.
* Fix 64-bit UB in BinaryenLiteral (#3136)Daniel Wirtz2020-09-161-1/+2
| | | The maximum storage size of type ids changed with the introduction of tuples, with their type id being the memory address of the canonicalized type vector. This change aligns the storage type of type ids in `BinaryenLiteral` with `Literal` by changing the type from `int32_t` to `uintptr_t`.
* Implement module and local names in name section (#3115)Daniel Wirtz2020-09-141-0/+13
| | | | | | | | | | | | | | | Adds support for the module and local subsections of the name section plus the respective C and JS APIs to populate and obtain local names. C API: * BinaryenFunctionGetNumLocals(func) * BinaryenFunctionHasLocalName(func, index) * BinaryenFunctionGetLocalName(func, index) * BinaryenFunctionSetLocalName(func, index, name) JS API: * Function.getNumLocals(func) * Function.hasLocalName(func, index) * Function.getLocalName(func, index) * Function.setLocalName(func, index, name)
* Add anyref feature and type (#3109)Daniel Wirtz2020-09-101-0/+2
| | | Adds `anyref` type, which is enabled by a new feature `--enable-anyref`. This type is primarily used for testing that passes correctly handle subtype relationships so that the codebase will continue to be prepared for future subtyping. Since `--enable-anyref` is meaningless without also using `--enable-reference-types`, this PR also makes it a validation error to pass only the former (and similarly makes it a validation error to enable exception handling without enabling reference types).
* Update reference types (#3084)Daniel Wirtz2020-09-091-2/+2
| | | | | | | Align with the current state of the reference types proposal: * Remove `nullref` * Remove `externref` and `funcref` subtyping * A `Literal` of a nullable reference type can now represent `null` (previously was type `nullref`) * Update the tests and temporarily comment out those tests relying on subtyping
* Improve inlining "heavyweight" (#3085)Max Graey2020-09-041-4/+4
| | | | | | | | | Split that mode into an option to check for loops (which indicate a function is "heavy") and a constant check for having calls. The case of calls is different as we would need more logic to avoid infinite recursion if we are willing to inling functions with calls. Practically, this renames allowHeavyweight to allowFunctionsWithLoops.
