* [reference-types] Support passive elem segments (#3572)Abbas Mashayekh2021-03-054-29/+37
| | | | | | | | | | | 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.

* Properly use text format type names in printing (#3591)Alon Zakai2021-02-232-6/+6
| | | | | | | | | | | | | | | | | | | This adds a TypeNames entry to modules, which can store names for types. So far this PR uses that to store type names from text format. Future PRs will add support for field names and for the binary format. (Field names are added to wasm.h here to see if we agree on this direction.) Most of the work here is threading a module through the various functions in Print.cpp. This keeps the module optional, so that we can still print an expression independently of a module, which has always been the case, and which I think we should keep (but, if a module was mandatory perhaps this would be a little simpler, and could be refactored into a form that depends on that). 99% of this diff are test updates, since almost all our tests use the text format, and many of them specify a type name but we used to ignore it. This is a step towards a proper solution for #3589
* [EH] Make rethrow's target a try label (#3568)Heejin Ahn2021-02-184-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Ahn2021-02-135-8/+71
| | | | | | | | | | 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).
* [reference-types] remove single table restriction in IR (#3517)Abbas Mashayekh2021-02-095-10/+29
| | | Adds support for modules with multiple tables. Adds a field for the table name to `CallIndirect` and updates the C/JS APIs accordingly.
* Prototype i32x4.widen_i8x16_{s,u} (#3535)Thomas Lively2021-02-012-32/+32
| | | | | | | | As proposed in https://github.com/WebAssembly/simd/pull/395. Note that the other instructions in the proposal have not been implemented in LLVM or in V8, so there is no need to implement them in Binaryen right now either. This PR introduces a new expression class for the new instructions because they uniquely take an immediate argument identifying which portion of the input vector to widen.
* [GC] Add br_on_func/data/i31 (#3525)Alon Zakai2021-01-282-2/+2
| | | | | | | | This expands the existing BrOnCast into BrOn that can also handle the func/data/i31 variants. This is not as elegant as RefIs / RefAs in that BrOnCast has an extra rtt field, but I think it is still the best option. We already have optional fields on Break (the value and condition), so making rtt optional is not odd. And it allows us to share all the behavior of br_on_* which aside from the cast or the check itself, is identical - returning the value if the branch is not taken, etc.
* [GC] ref.is_func/data/i31 (#3519)Alon Zakai2021-01-261-0/+16
|
* [GC] RefIsNull => RefIs. (#3516)Alon Zakai2021-01-264-19/+19
| | | | | | | | 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 Ahn2021-01-232-1/+13
| | | | | | | | | | 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 Ahn2021-01-224-80/+22
| | | This removes `exnref` type and `br_on_exn` instruction.
* [GC] Add dataref type (#3500)Alon Zakai2021-01-211-2/+2
| | | | | This is not 100% of everything, but is enough to get tests passing, which includes full binary and text format support, getting all switches to compile without error, and some additions to InstrumentLocals.
* Simplify set/gets of vectors in binaryen.js (#3495)Heejin Ahn2021-01-201-8/+19
| | | | | This uses existing `getAllNested` function in `ExpressionWrapper` functions. Also adds `setAllNested` which works in the other direction and uses it within `ExpressionWrapper` functions.
* Basic EH instrucion support for the new spec (#3487)Heejin Ahn2021-01-157-91/+142
| | | | | | | | | | | | | | | | | | | | 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 prefetch instructions (#3467)Thomas Lively2021-01-062-45/+45
| | | | As proposed in https://github.com/WebAssembly/simd/pull/352, using the opcodes used in the LLVM and V8 implementations.
* Prototype SIMD extending pairwise add instructions (#3466)Thomas Lively2021-01-052-22/+0
| | | | | | 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 Wirtz2021-01-052-1/+12
| | | | | | * 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
* Refactor printing code so that printing Expressions always works (#3450)Alon Zakai2020-12-172-4/+4
| | | | | | | | This avoids needing to add include wasm-printing if a file doesn't already have it. To achieve that, add the std::ostream hooks in wasm.h, and also use them when possible, removing the need for the special WasmPrinter object. Also stop printing in "full" (print types on each line) in error messages by default. The user can still get that, as always, using BINARYEN_PRINT_FULL=1 in the env.
* [TypedFunctionReferences] Implement call_ref (#3396)Alon Zakai2020-11-242-12/+14
| | | | | | | | Includes minimal support in various passes. Also includes actual optimization work in Directize, which was easy to add. Almost has fuzzer support, but the actual makeCallRef is just a stub so far. Includes s-parser support for parsing typed function references types.
* [TypedFunctionReferences] Add Typed Function References feature and use the ↵Alon Zakai2020-11-233-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Ahn2020-11-136-18/+18
| | | | | | | | | | | | | | - 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.
* [wasm2js] Use native JavaScript Math.trunc (#3329)Max Graey2020-11-101-0/+1

* wasm2js: Remove global dict arguments to asmFunc (#3325)Sam Clegg2020-11-051-26/+13

* Implement v128.{load,store}{8,16,32,64}_lane instructions (#3278)Thomas Lively2020-10-222-33/+33
| | | | | | | 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.
* Add C and JS APIs for fast math (#3188)Max Graey2020-10-012-0/+4
| | | 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 Wirtz2020-09-292-0/+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.
* Prototype extended-name-section proposal (#3162)Daniel Wirtz2020-09-293-12/+36
| | | Implements the parts of the Extended Name Section Proposal that are trivially applicable to Binaryen, in particular table, memory and global names. Does not yet implement label, type, elem and data names.
* wasm2js: Skip heap creation in the absence of wasm memory. NFC (#3167)Sam Clegg2020-09-241-11/+16
| | | | | Also, format the asmFunc call to make it more readable in the ES6 modules case.
* GC: Add i31 instructions (#3154)Daniel Wirtz2020-09-244-0/+128
| | | 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 Wirtz2020-09-212-0/+2
|
* GC: Add ref.eq instruction (#3145)Daniel Wirtz2020-09-215-9/+69
| | | 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 Wirtz2020-09-192-5/+36
| | | 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.
* Initial implementation of "Memory64" proposal (#3130)Wouter van Oortmerssen2020-09-181-1/+1
| | | Also includes a lot of new spec tests that eventually need to go into the spec repo
* Update JS API function wrapper (#3128)Daniel Wirtz2020-09-183-1/+55
| | | Updates the JS API `Function` wrapper introduced in #3115 with bindings for more C API functions. Also adds additional comments to describe the inner workings of wrappers in more detail.
* Refactor Host expression to MemorySize and MemoryGrow (#3137)Daniel Wirtz2020-09-175-59/+101
| | | 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 Wirtz2020-09-172-2/+2
| | | 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.
* Implement module and local names in name section (#3115)Daniel Wirtz2020-09-142-0/+64
| | | | | | | | | | | | | | | 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)
* Update Pop text format to handle tuples (#3116)Thomas Lively2020-09-112-19/+19
| | | | | | | | | | | Previously Pops were printed as ({type}.pop), and if the popped type was a tuple, something like ((i32, i64).pop) would get printed. However, the parser didn't support pops of anything besides single basic types. This PR changes the text format to be (pop <type>*) and adds support for parsing pops of tuples of basic types. The text format change is designed to make parsing simpler. This change is necessary for writing Poppy IR tests (see #3059) that contain break or return instructions that consume multiple values, since in Poppy IR that requires tuple-typed pops.
* Add anyref feature and type (#3109)Daniel Wirtz2020-09-103-2/+11
| | | 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 Wirtz2020-09-093-39/+48
| | | | | | | 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 Graey2020-09-042-4/+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.
* Add Binaryen(Get|Set)AllowHeavyweight to binaryen-c.h (#3082)Max Graey2020-08-282-0/+5
| | | These declarations were previously missing causing the respective APIs to be not exposed. Also makes sure that a Boolean is returned by the JS API and adds a test to verify that it is working now.

For example: var unary = binaryen.Unary(module.i32.eqz(1)); unary.getOp(...) / .op unary.setOp(...) / .op = ... unary.getValue(...) / .value unary.setValue(...) / .value = ... unary.getType(...) / .type unary.finalize() ... Usage of wrappers is optional, and one can also use plain functions: var unary = module.i32.eqz(1); binaryen.Unary.getOp(unary, ...) ... Also adds comments to all affected functions in case we'd like to generate API documentation at some point.
