* Remove C API tracing (#2841)Daniel Wirtz2020-05-0812-6713/+0
| | | | | | This feature was very useful in the early days of the C API, but has not shown usefuless for quite a while, and has a significant maintenance burden, so it it's makes sense to remove it now.
* Add snake_case method names for returnCall/returnCallIndirect in JS API (#2795)Shao Cheng2020-04-232-5/+5
|
* Add BinaryenCallIsReturn/BinaryenCallIndirectIsReturn to C/JS API (#2779)Shao Cheng2020-04-222-0/+38

* Refactor expression runner so it can be used via the C and JS APIs (#2702)Daniel Wirtz2020-04-207-0/+376
| | | | | | | Refactors most of the precompute pass's expression runner into its base class so it can also be used via the C and JS APIs. Also adds the option to populate the runner with known constant local and global values upfront, and remembers assigned intermediate values as well as traversing into functions if requested.
* Use direct pointers as Type IDs (#2745)Thomas Lively2020-04-136-137/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using indices into the global interned type table. This means that a lock is *never* needed to access an expanded Type. The Type lock is now only acquired when a complex Type is created. On a real-world wasm2js workload this improves wall clock time by 23% on my machine with 72 cores and makes traffic on the Type lock entirely insignificant. **Before** 72 cores real 0m6.914s user 184.014s sys 0m3.995s 1 core real 0m25.903s user 0m25.658s sys 0m0.253s **After** 72 cores real 5.349s user 70.309s sys 9.691s 1 core real 25.859s user 25.615s sys 0.253s
* Remove function index printing (#2742)Thomas Lively2020-04-0911-66/+66
| | | | | | | | `BinaryIndexes` was only used in two places (Print.cpp and wasm-binary.h), so it didn't seem to be a great fit for module-utils.h. This change moves it to wasm-binary.h and removes its usage in Print.cpp. This means that function indexes are no longer printed, but those were of limited utility and were the source of annoying noise when updating tests, anyway.
* Tuple operations in C and JS APIs (#2711)Thomas Lively2020-03-262-56/+197
| | | | Adds functions for creating and inspecting tuple.make and tuple.extract expressions in the C and JS APIs.
* SIMD integer abs and bitmask instructions (#2703)Thomas Lively2020-03-202-726/+883
| | | | | | Adds full support for the {i8x16,i16x8,i32x4}.abs instructions merged to the SIMD proposal in https://github.com/WebAssembly/simd/pull/128 as well as the {i8x16,i16x8,i32x4}.bitmask instructions proposed in https://github.com/WebAssembly/simd/pull/201.
* Initial multivalue support (#2675)Thomas Lively2020-03-051-1/+1
| | | | | | | | | Implements parsing and emitting of tuple creation and extraction and tuple-typed control flow for both the text and binary formats. TODO: - Extend Precompute/interpreter to handle tuple values - C and JS API support/testing - Figure out how to lower in stack IR - Fuzzing
* Add multivalue feature (#2668)Thomas Lively2020-02-272-2/+4
|
* Add the GetFunctionTable JS API (#2554)COFFEETALES2020-02-202-9/+25
|
* Add C-/JS-APIs for inlining options (#2655)Daniel Wirtz2020-02-132-0/+43
| | | | | | | | | | Allows a user to modify the inlining limits using the C- and JS-APIs. * binaryen.**getAlwaysInlineMaxSize**(): `number` * binaryen.**setAlwaysInlineMaxSize**(size: `number`): `void` * binaryen.**getFlexibleInlineMaxSize**(): `number` * binaryen.**setFlexibleInlineMaxSize**(size: `number`): `void` * binaryen.**getOneCallerInlineMaxSize**(): `number` * binaryen.**setOneCallerInlineMaxSize**(size: `number`): `void`
* Add C-/JS-APIs for lowMemoryUnused and pass arguments (#2639)Daniel Wirtz2020-02-074-0/+157
| | | | | | | | | Allows a user to enable/disable the `lowMemoryUnused` option and to get/set/clear arbitrary pass arguments when using the C- or JS-APIs. * binaryen.**getLowMemoryUnused**(): `boolean` * binaryen.**setLowMemoryUnused**(on: `boolean`): `void` * binaryen.**getPassArgument**(key: `string`): `string | null` * binaryen.**setPassArgument**(key: `string`, value: `string | null`): `void` * binaryen.**clearPassArguments**(): `void`
* Add EH support for EffectAnalyzer (#2631)Heejin Ahn2020-02-032-1/+14
| | | | | | | | | | | | | | | | | | | | This adds EH support to `EffectAnalyzer`. Before `throw` and `rethrow` conservatively set property. Now `EffectAnalyzer` has a new property `throws` to represent an expression that can throw, and expression that can throw sets `throws` correctly. When EH is enabled, any calls can throw too, so we cannot reorder them with another expression with any side effects, meaning all calls should be treated in the same way as branches when evaluating `invalidate`. This prevents many reorderings, so this patch sets `throws` for calls only when the exception handling features is enabled. This is also why I passed `--disable-exception-handling` to `wasm2js` tests. Most of code changes outside of `EffectAnalyzer` class was made in order to pass `FeatureSet` to it. `throws` isn't always set whenever an expression contains a throwable instruction. When an throwable instruction is within an inner try, it will be caught by the corresponding inner catch, so it does not set `throws`.
* Unify JS memory segment API (#2533)Daniel Wirtz2020-01-211-3/+5
| | | | | | | | | | Binaryen.js now uses offset instead of byteOffset when inspecting a memory segment, matching the arguments on memory segment creation. Also adds inspection of the passive property. Previously, one would specify { offset, data, passive } on creation and get back { byteOffset, data } upon inspection. This PR unifies both to the keys on creation while also adding the respective C-API to retrieve passive status, which was missing.
* Expose ExpressionAnalyzer in C-/JS-API (#2585)Daniel Wirtz2020-01-172-0/+106
| | | | | | | Instead of reinventing the wheel on our side, this adds ExpressionAnalyzer bindings to the C- and JS-APIs, which can be useful for generators. For example, a generator may decide to simplify a compilation step if a subexpression doesn't have any side effects, or simply skip emitting something that is likely to compile to a drop or an empty block right away.
* Align binaryen.js with the npm package (#2551)Daniel Wirtz2020-01-1419-826/+693
| | | | | Binaryen.js now uses binaryen (was Binaryen) as its global name to align with the npm package. Also fixes issues with emitting and testing both the JS and Wasm builds.
* Add support for reference types proposal (#2451)Heejin Ahn2019-12-306-121/+245
| | | | | | | | | | | | This adds support for the reference type proposal. This includes support for all reference types (`anyref`, `funcref`(=`anyfunc`), and `nullref`) and four new instructions: `ref.null`, `ref.is_null`, `ref.func`, and new typed `select`. This also adds subtype relationship support between reference types. This does not include table instructions yet. This also does not include wasm2js support. Fixes #2444 and fixes #2447.
* Fix for binaryen.js getExpressionInfo on switch names (#2553)Brion Vibber2019-12-232-2/+2
| | | | | | | | | | | | Switch label names for br_table instructions were corrupted in the binaryen.js API layer, with each label cropped down to the number of characters that it is an index into the list. This was due to passing UTF8ToString as a callback method to Array.prototype.map, which passes the index as second parameter. The second parameter of UTF8ToString is the max number of bytes to copy, so the initial label came out as '', then 'l', then 'la', 'lab', etc. Corrected an existing test case that had the wrong output in it.
* Compile Binaryen to WebAssembly (#2503)Daniel Wirtz2019-12-1919-472/+544
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR enables compiling Binaryen to WebAssembly when building binaryen.js. Since WebAssembly is best compiled and instantiated asynchronously in browsers, it also adds a new mechanism to tell if respectively when the module is ready by means of one of the following: // Using a promise const binaryen = require("binaryen"); binaryen.ready.then(() => { ... use normally ... }); // Using await const binaryen = require("binaryen"); (async () => { await binaryen.ready; ... use normally ... })(); // Where top-level await is available const binaryen = await require("binaryen").ready; ... use normally ... One can also tell if Binaryen is already ready (for example when assuming it in follow-up code) by: if (/* we already know that */ binaryen.isReady) { ... use normally ... } else { throw Error("Binaryen is supposed to be ready here but isn't"); } The JS test cases have been updated accordingly by wrapping everything in a test function and invoking it once ready. Documentation will have to be updated as well to cover this of course. New file size is about 2.5mb, even though the Wasm becomes inlined into the JS file which makes distribution across different environments a lot easier. Also makes building binaryen (to either js or wasm) emit binaryen.js, and not binaryen_js.js etc. Supersedes and thus fixes #1381 With .ready it also fixes #2452
* SIMD {i8x16,i16x8}.avgr_u instructions (#2539)Thomas Lively2019-12-182-294/+363
| | | As specified in https://github.com/WebAssembly/simd/pull/126.
* Make local.tee's type its local's type (#2511)Heejin Ahn2019-12-122-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the current spec, `local.tee`'s return type should be the same as its local's type. (Discussions on whether we should change this rule is going on in WebAssembly/reference-types#55, but here I will assume this spec does not change. If this changes, we should change many parts of Binaryen transformation anyway...) But currently in Binaryen `local.tee`'s type is computed from its value's type. This didn't make any difference in the MVP, but after we have subtype relationship in #2451, this can become a problem. For example: ``` (func $test (result funcref) (local $0 anyref) (local.tee $0 (ref.func $test) ) ) ``` This shouldn't validate in the spec, but this will pass Binaryen validation with the current `local.tee` implementation. This makes `local.tee`'s type computed from the local's type, and makes `LocalSet::makeTee` get a type parameter, to which we should pass the its corresponding local's type. We don't embed the local type in the class `LocalSet` because it may increase memory size. This also fixes the type of `local.get` to be the local type where `local.get` and `local.set` pair is created from `local.tee`.
* Remove FunctionType (#2510)Thomas Lively2019-12-1127-2656/+2582
| | | | | | | | | | | | | | | | | Function signatures were previously redundantly stored on Function objects as well as on FunctionType objects. These two signature representations had to always be kept in sync, which was error-prone and needlessly complex. This PR takes advantage of the new ability of Type to represent multiple value types by consolidating function signatures as a pair of Types (params and results) stored on the Function object. Since there are no longer module-global named function types, significant changes had to be made to the printing and emitting of function types, as well as their parsing and manipulation in various passes. The C and JS APIs and their tests also had to be updated to remove named function types.
* Fix comparison of none and unreachable types (#2514)Heejin Ahn2019-12-091-2/+2
| | | | | | | | | | | | | | | | | | | Currently `none` and `unreachable` types are stored as the same empty `{}` in src/wasm/wasm-type.cpp. This makes `Type::operator<` incorrectly when given `none` and `unreachable`, because it expands both given types and lexicographically compare them, when both of the expanded vector will be empty. This was found by the fuzzer. This line in `Modder::visitExpression` tries to retrieve candidates of the same type. Because we can't really compare these two types, if you give `unreachable` as the key, candidates of `none` type can be returned. This generates incorrect code that ends up failing in validation in a very weird way. It was hard to generate a small testcase to trigger this part because it was found by generating fuzzed code from a random data file. But I guess this fix is pretty straightforward. Fixes #2512.
* Don't include `$` with names unless outputting to wat format (#2506)Sam Clegg2019-12-063-5/+5
| | | | | | | | | | | The `$` is not actually part of the name, its the marker that starts a name in the wat format. It can be confusing to see it show up when doing `cerr << name`, for example. This change has Print.cpp add the `$` which seem like the right place to do this. Plus it revealed a bunch of places where were not calling printName to escape all the names we were printing.
* Print only literal values when printing literals (#2469)Heejin Ahn2019-11-261-1/+1
| | | | | | | | | | | | | | | Current `<<` operator on `Literal` prints `[type].const` with it. But `[type].const` is rather an instruction than a literal itself, and printing it with the literals makes less sense when we later have literals whose type don't have `const` instructions (such as reference types). This patch - Makes `<<` operator on `Literal` print only its value - Makes wasm-shell's shell interface comply with the spec interpreter's printing format (`value : type`). - Prints wasm-shell's `[trap]` message to stderr These make all `fix_` routines for spec tests in check.py unnecessary.
* Remove FunctionType from Event (#2466)Thomas Lively2019-11-256-45/+26
| | | | | | | | | This is the start of a larger refactoring to remove FunctionType entirely and store types and signatures directly on the entities that use them. This PR updates BrOnExn and Events to remove their use of FunctionType and makes the BinaryWriter traverse the module and collect types rather than using the global FunctionType list. While we are collecting types, we also sort them by frequency as an optimization. Remaining uses of FunctionType in Function, CallIndirect, and parsing will be removed in a future PR.
* Multivalue type creation and inspection (#2459)Thomas Lively2019-11-225-94/+168
| | | | | | | | | | | | | Adds the ability to create multivalue types from vectors of concrete value types. All types are transparently interned, so their representation is still a single uint32_t. Types can be extracted into vectors of their component parts, and all the single value types expand into vectors containing themselves. Multivalue types are not yet used in the IR, but their creation and inspection functionality is exposed and tested in the C and JS APIs. Also makes common type predicates methods of Type and improves the ergonomics of type printing.
* Add i32x4.dot_i16x8_s (#2420)Thomas Lively2019-11-042-297/+331
| | | | | This experimental instruction is specified in https://github.com/WebAssembly/simd/pull/127 and is being implemented to enable further investigation of its performance impact.
* Add SIMD integer min and max instructions (#2416)Thomas Lively2019-11-012-314/+724
| | | As proposed in https://github.com/WebAssembly/simd/pull/27.
* Convert usage of Pointer_stringify to UTF8ToString (#2403)Brad Morris2019-10-232-0/+4
| | | | This fixes #2396. This converts the use of the old Pointer_stringify to the new UTF8ToString. Added a js test in kitchen-sink.js to cover this.
* Fix incorrect assert in BinaryenHostGetOperand (#2393)Brad Morris2019-10-222-0/+12
|
* Ability to list each item on Exports/Data Segments/Functions (#2386)COFFEETALES2019-10-212-0/+75
| | | Adds functionality to the C API for getting the number of items in a module and fetching them out by index.
* Add BinaryenAddCustomSection API (#2381)Daniel Wirtz2019-10-112-0/+37
| | | | This adds a new BinaryenAddCustomSection API so a generator can add arbitrary custom sections to a module.
* Add offset parameter to BinaryenSetFunctionTable (#2380)Daniel Wirtz2019-10-113-5/+45
| | | | | | This PR adds an offset parameter to BinaryenSetFunctionTable so table elements can start at the value of an (imported constant) global. Previously, the offset was fixed to zero. As usual this is a breaking change to the C-API but backwards compatible when using the JS-API.
* Add push/pop support for anyref (#2376)Heejin Ahn2019-10-104-34/+55
| | | | This adds push/pop support for anyref. This also adds missing C API tests for push/pop.
* v8x16.swizzle (#2368)Thomas Lively2019-10-032-293/+327
| | | | As specified at https://github.com/WebAssembly/simd/blob/master/proposals/simd/SIMD.md#swizzling-using-variable-indices.
* SIMD load and extend instructions (#2353)Thomas Lively2019-09-242-197/+336
| | | | | | Adds support for the new load and extend instructions. Also updates from C++11 to C++17 in order to use generic lambdas in the interpreter implementation.
* v128.andnot instruction (#2355)Thomas Lively2019-09-242-307/+377
| | | | | As specified at https://github.com/WebAssembly/simd/pull/102. Also fixes bugs in the JS API for other SIMD bitwise operators.
* vNxM.load_splat instructions (#2350)Thomas Lively2019-09-234-220/+316
| | | | | | | Introduces a new instruction class, `SIMDLoad`. Implements encoding, decoding, parsing, printing, and interpretation of the load and splat instructions, including in the C and JS APIs. `v128.load` remains in the `Load` instruction class for now because the interpreter code expects a `Load` to be able to load any memory value type.
* SIMD narrowing and widening operations (#2341)Thomas Lively2019-09-142-636/+982
|
* QFMA/QFMS instructions (#2328)Thomas Lively2019-09-032-184/+353
| | | | | | | | | Renames the SIMDBitselect class to SIMDTernary and adds the new {f32x4,f64x2}.qfm{a,s} ternary instructions. Because the SIMDBitselect class is no more, this is a backwards-incompatible change to the C interface. The new instructions are not yet used in the fuzzer because they are not yet implemented in V8. The corresponding LLVM commit is https://reviews.llvm.org/rL370556.
* Add mutable parameter to global imports in C/JS API (#2317)Daniel Wirtz2019-09-034-3/+13
|
* Add missing new features to the C and JS APIs (#2312)Daniel Wirtz2019-08-282-0/+4
|
* Add atomic.fence instruction (#2307)Heejin Ahn2019-08-276-80/+240
| | | | | | | This adds `atomic.fence` instruction: https://github.com/WebAssembly/threads/blob/master/proposals/threads/Overview.md#fence-operator This also fix bugs in `atomic.wait` and `atomic.notify` instructions in binaryen.js and adds tests for them.
* Remove test output from source tree (#2114)Sam Clegg2019-08-211-1/+1
|
* Add initial support for anyref as an opaque type (#2294)Jay Phelps2019-08-204-12/+14
| | | | | | | | | | | | | Another round of trying to push upstream things from my fork. This PR only adds support for anyref itself as an opaque type. It does NOT implement the full [reference types proposal](https://github.com/WebAssembly/reference-types/blob/master/proposals/reference-types/Overview.md)--so no table.get/set/grow/etc or ref.null, ref.func, etc. Figured it was easier to review and merge as we go, especially if I did something fundamentally wrong. *** I did put it under the `--enable-reference-types` flag as I imagine that even though this PR doesn't complete the full feature set, it probably is the right home. Lmk if not. I'll also be adding a few github comments to places I want to point out/question.
* Add basic exception handling support (#2282)Heejin Ahn2019-08-134-62/+3082
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds basic support for exception handling instructions, according to the spec: https://github.com/WebAssembly/exception-handling/blob/master/proposals/Exceptions.md This PR includes support for: - Binary reading/writing - Wast reading/writing - Stack IR - Validation - binaryen.js + C API - Few IR routines: branch-utils, type-updating, etc - Few passes: just enough to make `wasm-opt -O` pass - Tests This PR does not include support for many optimization passes, fuzzer, or interpreter. They will be follow-up PRs. Try-catch construct is modeled in Binaryen IR in a similar manner to that of if-else: each of try body and catch body will contain a block, which can be omitted if there is only a single instruction. This block will not be emitted in wast or binary, as in if-else. As in if-else, `class Try` contains two expressions each for try body and catch body, and `catch` is not modeled as an instruction. `exnref` value pushed by `catch` is get by `pop` instruction. `br_on_exn` is special: it returns different types of values when taken and not taken. We make `exnref`, the type `br_on_exn` pushes if not taken, as `br_on_exn`'s type.
* Remove trailing whitespaces after 'else' in stack IR (#2284)Heejin Ahn2019-08-061-2/+2
|
* Make sure binaryen.js tests validate (#2269)Heejin Ahn2019-07-2911-12/+61
| | | | | | Without `assert`, even if a test does not validate, the errors will only show up in its corresponding `.txt` file while the test will succeed. This makes sure it errors out when a test fails to validate. This also adds validation checks if there is none.
