* v8x16.swizzle (#2368)Thomas Lively2019-10-031-0/+1
| | | | 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 Lively2019-09-241-0/+18
| | | | | | 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 Lively2019-09-241-0/+1
| | | | | 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 Lively2019-09-231-0/+62
| | | | | | | 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 Lively2019-09-141-0/+36
|
* QFMA/QFMS instructions (#2328)Thomas Lively2019-09-031-27/+43
| | | | | | | | | 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 Wirtz2019-09-031-2/+4
|
* Add missing new features to the C and JS APIs (#2312)Daniel Wirtz2019-08-281-0/+6
|
* Add atomic.fence instruction (#2307)Heejin Ahn2019-08-271-0/+23
| | | | | | | 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 Phelps2019-08-201-0/+4
| | | | | | | | | | | | | 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 Ahn2019-08-131-0/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* More push/pop support (#2260)Heejin Ahn2019-07-241-0/+27
| | | | | | | This adds - `push`/`pop` support for other types: v128 and exnref - `push`/`pop` support for binaryen.js Because binaryen.js follows Binaryen's AST structure, without `pop` in binaryen.js, EH instructions cannot be represented in binaryen.js.
* Remove extra parens from binaryen-c.cpp (NFC) (#2262)Heejin Ahn2019-07-241-21/+21

* Simpify PassRunner.add() and automatically parallelize parallel functions ↵Alon Zakai2019-07-191-4/+2
| | | | | | | | | (#2242) Main change here is in pass.h, everything else is changes to work with the new API. The add("name") remains as before, while the weird variadic add(..) which constructed the pass now just gets a std::unique_ptr of a pass. This also makes the memory management internally fully automatic. And it makes it trivial to parallelize WalkerPass::run on parallel passes. As a benefit, this allows removing a lot of code since in many cases there is no need to create a new pass runner, and running a pass can be just a single line.
* Tail call C/JS API (#2223)Thomas Lively2019-07-151-17/+56
|
* Rename except_ref type to exnref (#2224)Heejin Ahn2019-07-141-4/+4
| | | | In WebAssembly/exception-handling#79 we agreed to rename `except_ref` type to `exnref`.
* Add event section (#2151)Heejin Ahn2019-05-311-0/+161
| | | | | | | | | | | | | | | | | | This adds support for the event and the event section, as specified in https://github.com/WebAssembly/exception-handling/blob/master/proposals/Exceptions.md#changes-to-the-binary-model. Wasm events are features that suspend the current execution and transfer the control flow to a corresponding handler. Currently the only supported event kind is exceptions. For events, this includes support for - Binary file reading/writing - Wast file reading/writing - Binaryen.js API - Fuzzer - Validation - Metadce - Passes: metrics, minify-imports-and-exports, remove-unused-module-elements
* Add Features.MVP and Features.All to binaryen.js (#2148)Heejin Ahn2019-05-291-0/+6
| | | | This adds `Features.MVP` and `Features.All` to binaryen.js and make test cases use it.
* Add `getGlobal` to binaryen.js (#2142)Heejin Ahn2019-05-241-0/+9
| | | | | We have `getFunction`, but not `getGlobal` because its name clashed with APIs for the deprecated instruction `get_global`. Now we have reflected instruction renaming in code, we can add it for consistency.
* Add BinaryenModuleWriteSExpr to write a module to a string in s-expr format ↵Siddharth2019-05-211-0/+37
| | | | | (#2106) Fixes #2103.
* Reflect instruction renaming in code (#2128)Heejin Ahn2019-05-211-61/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Reflected new renamed instruction names in code and tests: - `get_local` -> `local.get` - `set_local` -> `local.set` - `tee_local` -> `local.tee` - `get_global` -> `global.get` - `set_global` -> `global.set` - `current_memory` -> `memory.size` - `grow_memory` -> `memory.grow` - Removed APIs related to old instruction names in Binaryen.js and added APIs with new names if they are missing. - Renamed `typedef SortedVector LocalSet` to `SetsOfLocals` to prevent name clashes. - Resolved several TODO renaming items in wasm-binary.h: - `TableSwitch` -> `BrTable` - `I32ConvertI64` -> `I32WrapI64` - `I64STruncI32` -> `I64SExtendI32` - `I64UTruncI32` -> `I64UExtendI32` - `F32ConvertF64` -> `F32DemoteI64` - `F64ConvertF32` -> `F64PromoteF32` - Renamed `BinaryenGetFeatures` and `BinaryenSetFeatures` to `BinaryenModuleGetFeatures` and `BinaryenModuleSetFeatures` for consistency.
* Features C/JS API (#2049)Thomas Lively2019-05-171-2/+42
| | | | | Add feature handling to the C/JS APIs. No features are enabled by default, so all used features will have to be explicitly enabled in order for modules to validate.
* Allow color API to enable and disable colors (#2111)Siddharth2019-05-171-0/+5
| | | | | | This is useful for front-ends which wish to selectively enable or disable coloring. Also expose these APIs from the C API.
* Add missing methods for globals to binaryen.js (#2099)Heejin Ahn2019-05-131-5/+47
| | | | | - Print `globals` array in the tracing mode like other arrays (`functions`, `exports`, `imports`, ...) - Add accessor functions for globals
* Add except_ref type (#2081)Heejin Ahn2019-05-071-0/+5
| | | | This adds except_ref type, which is a part of the exception handling proposal.
* clang-tidy braces changes (#2075)Alon Zakai2019-05-011-39/+73
| | | Applies the changes in #2065, and temprarily disables the hook since it's too slow to run on a change this large. We should re-enable it in a later commit.
* Apply format changes from #2048 (#2059)Alon Zakai2019-04-261-411/+1079
| | | Mass change to apply clang-format to everything. We are applying this in a PR by me so the (git) blame is all mine ;) but @aheejin did all the work to get clang-format set up and all the manual work to tidy up some things to make the output nicer in #2048
* wasm2js: more js optimization (#2050)Alon Zakai2019-04-241-1/+1
| | | | | | * Emit ints as signed, so -1 isn't a big unsigned number. * x - -c (where c is a constant) is larger than x + c in js (but not wasm) * +(+x) => +x * Avoid unnecessary coercions on calls, return, load, etc. - we just need coercions when entering or exiting "wasm" (not internally), and on actual operations that need them.
* Move features from passOptions to Module (#2001)Thomas Lively2019-04-121-3/+3
| | | | | This allows us to emit a (potentially modified) target features section and conditionally emit other sections such as the DataCount section based on the presence of features.
* Wasm2js refactoring (#1997)Alon Zakai2019-04-111-4/+7
| | | | | | | | | | | | | Early work for #1929 * Leave core wasm module - the "asm.js function" - to Wasm2JSBuilder, and add Wasm2JSGlue which emits the code before and after that. Currently that's some ES6 code, but we may want to change that later. * Add add AssertionEmitter class for the sole purpose of emitting modules + assertions for testing. This avoids some hacks from before like starting from index 1 (assuming the module at first position was already parsed and printed) and printing of the f32Equal etc. functions not at the very top (which was due to technical limitations before). Logic-wise, there should be no visible change, except some whitespace and reodering, and that I made the exceptions print out the source of the assertion that failed from the wast: -if (!check2()) fail2(); +if (!check2()) throw 'assertion failed: ( assert_return ( call add ( i32.const 1 ) ( i32.const 1 ) ) ( i32.const 2 ) )'; (fail2 etc. did not exist, and seems to just have given a unique number for each assertion?)
* Passive segments (#1976)Thomas Lively2019-04-051-3/+10
| | | | | Adds support for the bulk memory proposal's passive segments. Uses a new (data passive ...) s-expression syntax to mark sections as passive.
* Rename atomic wait/notify instructions (#1972)Heejin Ahn2019-03-301-13/+13
| | | | | | | | This renames the following: - `i32.wait` -> `i32.atomic.wait` - `i64.wait` -> `i64.atomic.wait` - `wake` -> `atomic.notify` to match the spec.
* Add BinaryenConstGetValueV128 to C/JS-API (#1931)Daniel Wirtz2019-03-131-1/+16
| | | | | | | This PR adds void BinaryenConstGetValueV128(BinaryenExpressionRef expr, uint8_t* out); to the C-API and uses it in Binaryen.getExpressionInfo in the JS-API.
* fix binaryen.js bindings handling of literals (#1896)Alon Zakai2019-02-061-0/+13
| | | The hardcoded 16 size was no longer valid. This was broken for a while, but happened to not overwrite important memory. Testing with the wasm backend did hit breakage.
* Bulk memory operations (#1892)Thomas Lively2019-02-051-0/+138
| | | | | | Bulk memory operations The only parts missing are the interpreter implementation and spec tests.
* Require unique_ptr to Module::addFunctionType() (#1672)Paweł Bylica2019-01-101-10/+6
| | | | | This fixes the memory leak in WasmBinaryBuilder::readSignatures() caused probably the exception thrown there before the FunctionType object is safe. This also makes it clear that the Module becomes the owner of the FunctionType objects.
* Rename `idx` to `index` in SIMD code for consistency (#1836)Thomas Lively2018-12-181-12/+12
|
* SIMD (#1820)Thomas Lively2018-12-131-30/+399
| | | | | | | | | Implement and test the following functionality for SIMD. - Parsing and printing - Assembling and disassembling - Interpretation - C API - JS API
* Use template magic for tracing expressions (#1815)Thomas Lively2018-12-101-89/+106
|
* Implement nontrapping float-to-int instructions (#1780)Thomas Lively2018-12-041-0/+8
|
* Feature options (#1797)Thomas Lively2018-12-031-1/+1
| | | | Add feature flags and struct interface. Default feature set has all feature enabled.
* Add v128 type (#1777)Thomas Lively2018-11-291-0/+2
|
* Remove default cases (#1757)Thomas Lively2018-11-271-3/+7
| | | | | | Where reasonable from a readability perspective, remove default cases in switches over types and instructions. This makes future feature additions easier by making the compiler complain about each location where new types and instructions are not yet handled.
* fix some () vs (void) C warnings in the C API (#1768)Alon Zakai2018-11-261-3/+3
| | | Fixes #1766
* Relooper CFG optimizations (#1759)Alon Zakai2018-11-211-6/+7
| | | | | | | | | | | | | | | | Previously the relooper would do some optimizations when deciding when to use an if vs a switch, how to group blocks, etc. This PR adds an additional pre-optimization phase with some basic but useful simplify-cfg style passes, * Skip empty blocks when they have just one exit. * Merge exiting branches when they are equivalent. * Canonicalize block contents to make such comparisons more useful. * Turn a trivial one-target switch into a simple branch. This can help in noticeable ways when running the rereloop pass, e.g. on LLVM wasm backend output. Also: * Binaryen C API changes to the relooper, which now gets a Module for its constructor. It needs it for the optimizations, as it may construct new nodes. * Many relooper-fuzzer improvements. * Clean up HashType usage.
* Shared memory support for add memory import and set memory functions. (#1686)Nidin Vinayakan2018-10-111-4/+6
|
* Add BinaryenRemoveGlobal / Module.removeGlobal to C/JS API (#1692)Daniel Wirtz2018-10-091-0/+8
|
* Add initial/maximum table size parameters to C/JS API (#1687)Daniel Wirtz2018-09-281-4/+5
|
* Unify imported and non-imported things (#1678)Alon Zakai2018-09-191-150/+54
| | | | | | | | | | | | | | Fixes #1649 This moves us to a single object for functions, which can be imported or nor, and likewise for globals (as a result, GetGlobals do not need to check if the global is imported or not, etc.). All imported things now inherit from Importable, which has the module and base of the import, and if they are set then it is an import. For convenient iteration, there are a few helpers like ModuleUtils::iterDefinedGlobals(wasm, [&](Global* global) { .. use global .. }); as often iteration only cares about imported or defined (non-imported) things.
