Similiar to objdump. - [**wasm-interp**](https://webassembly.github.io/wabt/doc/wasm-interp.1.html): decode and run a WebAssembly binary file using a stack-based interpreter - [**wasm-decompile**](https://webassembly.github.io/wabt/doc/wasm-decompile.1.html): decompile a wasm binary into readable C-like syntax. - [**wat-desugar**](https://webassembly.github.io/wabt/doc/wat-desugar.1.html): parse .wat text form as supported by the spec interpreter (s-expressions, flat syntax, or mixed) and print "canonical" flat format - [**wasm2c**](https://webassembly.github.io/wabt/doc/wasm2c.1.html): convert a WebAssembly binary file to a C source and header - [**wasm-strip**](https://webassembly.github.io/wabt/doc/wasm-strip.1.html): remove sections of a WebAssembly binary file - [**wasm-validate**](https://webassembly.github.io/wabt/doc/wasm-validate.1.html): validate a file in the WebAssembly binary format - [**wast2json**](https://webassembly.github.io/wabt/doc/wast2json.1.html): convert a file in the wasm spec test format to a JSON file and associated wasm binary files - [**wasm-stats**](https://webassembly.github.io/wabt/doc/wasm-stats.1.html): output stats for a module - [**spectest-interp**](https://webassembly.github.io/wabt/doc/spectest-interp.1.html): read a Spectest JSON file, and run its tests in the interpreter These tools are intended for use in (or for development of) toolchains or other systems that want to manipulate WebAssembly files. Unlike the WebAssembly spec interpreter (which is written to be as simple, declarative and "speccy" as possible), they are written in C/C++ and designed for easier integration into other systems. Unlike [Binaryen](https://github.com/WebAssembly/binaryen) these tools do not aim to provide an optimization platform or a higher-level compiler target; instead they aim for full fidelity and compliance with the spec (e.g. 1:1 round-trips with no changes to instructions). ## Online Demos Wabt has been compiled to JavaScript via emscripten. Some of the functionality is available in the following demos: - [index](https://webassembly.github.io/wabt/demo/) - [wat2wasm](https://webassembly.github.io/wabt/demo/wat2wasm/) - [wasm2wat](https://webassembly.github.io/wabt/demo/wasm2wat/) ## Supported Proposals * Proposal: Name and link to the WebAssembly proposal repo * flag: Flag to pass to the tool to enable/disable support for the feature * default: Whether the feature is enabled by default * binary: Whether wabt can read/write the binary format * text: Whether wabt can read/write the text format * validate: Whether wabt can validate the syntax * interpret: Whether wabt can execute these operations in `wasm-interp` or `spectest-interp` * wasm2c: Whether wasm2c supports these operations | Proposal | flag | default | binary | text | validate | interpret | wasm2c | | --------------------- | --------------------------- | - | - | - | - | - | - | | [exception handling][]| `--enable-exceptions` | | ✓ | ✓ | ✓ | ✓ | ✓ | | [mutable globals][] | `--disable-mutable-globals` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | [nontrapping float-to-int conversions][] | `--disable-saturating-float-to-int` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | [sign extension][] | `--disable-sign-extension` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | [simd][] | `--disable-simd` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | [threads][] | `--enable-threads` | | ✓ | ✓ | ✓ | ✓ | | | [multi-value][] | `--disable-multi-value` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | [tail-call][] | `--enable-tail-call` | | ✓ | ✓ | ✓ | ✓ | ✓ | | [bulk memory][] | `--disable-bulk-memory` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | [reference types][] | `--disable-reference-types` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | [annotations][] | `--enable-annotations` | | | ✓ | | | | | [memory64][] | `--enable-memory64` | | ✓ | ✓ | ✓ | ✓ | ✓ | | [multi-memory][] | `--enable-multi-memory` | | ✓ | ✓ | ✓ | ✓ | ✓ | | [extended-const][] | `--enable-extended-const` | | ✓ | ✓ | ✓ | ✓ | ✓ | | [relaxed-simd][] | `--enable-relaxed-simd` | | ✓ | ✓ | ✓ | ✓ | | | [custom-page-sizes][] | `--enable-custom-page-sizes`| | ✓ | ✓ | ✓ | ✓ | ✓ | | [compact-imports][] | `--enable-compact-imports` | | ✓ | | ✓ | | | | [function-references][] | `--enable-function-references` | | ✓ | ✓ | ✓ | ✓ | | | [wide-arithmetic][] | `--enable-wide-arithmetic` | | ✓ | ✓ | ✓ | | | [exception handling]: https://github.com/WebAssembly/exception-handling [mutable globals]: https://github.com/WebAssembly/mutable-global [nontrapping float-to-int conversions]: https://github.com/WebAssembly/nontrapping-float-to-int-conversions [sign extension]: https://github.com/WebAssembly/sign-extension-ops [simd]: https://github.com/WebAssembly/simd [threads]: https://github.com/WebAssembly/threads [multi-value]: https://github.com/WebAssembly/multi-value [tail-call]: https://github.com/WebAssembly/tail-call [bulk memory]: https://github.com/WebAssembly/bulk-memory-operations [reference types]: https://github.com/WebAssembly/reference-types [annotations]: https://github.com/WebAssembly/annotations [memory64]: https://github.com/WebAssembly/memory64 [multi-memory]: https://github.com/WebAssembly/multi-memory [extended-const]: https://github.com/WebAssembly/extended-const [relaxed-simd]: https://github.com/WebAssembly/relaxed-simd [custom-page-sizes]: https://github.com/WebAssembly/custom-page-sizes [function-references]: https://github.com/WebAssembly/function-references [compact-imports]: https://github.com/WebAssembly/compact-import-section [wide-arithmetic]: https://github.com/WebAssembly/wide-arithmetic ## Cloning Clone as normal, but don't forget to get the submodules as well: ```console $ git clone --recursive https://github.com/WebAssembly/wabt $ cd wabt $ git submodule update --init ``` This will fetch the testsuite and gtest repos, which are needed for some tests. ## Building using CMake directly (Linux and macOS) You'll need [CMake](https://cmake.org). You can then run CMake, the normal way: ```console $ mkdir build $ cd build $ cmake .. $ cmake --build . ``` This will produce build files using CMake's default build generator. Read the CMake documentation for more information. **NOTE**: You must create a separate directory for the build artifacts (e.g. `build` above). Running `cmake` from the repo root directory will not work since the build produces an executable called `wasm2c` which conflicts with the `wasm2c` directory. ## Building using the top-level `Makefile` (Linux and macOS) **NOTE**: Under the hood, this uses `make` to run CMake, which then calls `ninja` to perform that actual build. On some systems (typically macOS), this doesn't build properly. If you see these errors, you can build using CMake directly as described above. You'll need [CMake](https://cmake.org) and [Ninja](https://ninja-build.org). If you just run `make`, it will run CMake for you, and put the result in `out/clang/Debug/` by default: > Note: If you are on macOS, you will need to use CMake version 3.2 or higher ```console $ make ``` This will build the default version of the tools: a debug build using the Clang compiler. There are many make targets available for other configurations as well. They are generated from every combination of a compiler, build type and configuration. - compilers: `gcc`, `clang`, `gcc-i686`, `emscripten` - build types: `debug`, `release` - configurations: empty, `asan`, `msan`, `lsan`, `ubsan`, `fuzz`, `no-tests` They are combined with dashes, for example: ```console $ make clang-debug $ make gcc-i686-release $ make clang-debug-lsan $ make gcc-debug-no-tests ``` ## Building (Windows) You'll need [CMake](https://cmake.org). You'll also need [Visual Studio](https://www.visualstudio.com/) (2015 or newer) or [MinGW](https://www.mingw-w64.org/). _Note: Visual Studio 2017 and later come with CMake (and the Ninja build system) out of the box, and should be on your PATH if you open a Developer Command prompt. See for more details._ You can run CMake from the command prompt, or use the CMake GUI tool. See [Running CMake](https://cmake.org/runningcmake/) for more information. When running from the commandline, create a new directory for the build artifacts, then run cmake from this directory: ```console > cd [build dir] > cmake [wabt project root] -DCMAKE_BUILD_TYPE=[config] -DCMAKE_INSTALL_PREFIX=[install directory] -G [generator] ``` The `[config]` parameter should be a CMake build type, typically `DEBUG` or `RELEASE`. The `[generator]` parameter should be the type of project you want to generate, for example `"Visual Studio 14 2015"`. You can see the list of available generators by running `cmake --help`. To build the project, you can use Visual Studio, or you can tell CMake to do it: ```console > cmake --build [wabt project root] --config [config] --target install ``` This will build and install to the installation directory you provided above. So, for example, if you want to build the debug configuration on Visual Studio 2015: ```console > mkdir build > cd build > cmake .. -DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_INSTALL_PREFIX=..\ -G "Visual Studio 14 2015" > cmake --build . --config DEBUG --target install ``` ## Adding new keywords to the lexer If you want to add new keywords, you'll need to install [gperf](https://www.gnu.org/software/gperf/). Before you upload your PR, please run `make update-gperf` to update the prebuilt C++ sources in `src/prebuilt/`. ## Running wat2wasm Some examples: ```sh # parse test.wat and write to .wasm binary file with the same name $ bin/wat2wasm test.wat # parse test.wat and write to binary file test.wasm $ bin/wat2wasm test.wat -o test.wasm # parse spec-test.wast, and write verbose output to stdout (including the # meaning of every byte) $ bin/wat2wasm spec-test.wast -v ``` You can use `--help` to get additional help: ```console $ bin/wat2wasm --help ``` Or try the [online demo](https://webassembly.github.io/wabt/demo/wat2wasm/). ## Running wasm2wat Some examples: ```sh # parse binary file test.wasm and write text file test.wat $ bin/wasm2wat test.wasm -o test.wat # parse test.wasm and write test.wat $ bin/wasm2wat test.wasm -o test.wat ``` You can use `--help` to get additional help: ```console $ bin/wasm2wat --help ``` Or try the [online demo](https://webassembly.github.io/wabt/demo/wasm2wat/). ## Running wasm-interp Some examples: ```sh # parse binary file test.wasm, and type-check it $ bin/wasm-interp test.wasm # parse test.wasm and run all its exported functions $ bin/wasm-interp test.wasm --run-all-exports # parse test.wasm, run the exported functions and trace the output $ bin/wasm-interp test.wasm --run-all-exports --trace # parse test.json and run the spec tests $ bin/wasm-interp test.json --spec # parse test.wasm and run all its exported functions, setting the value stack # size to 100 elements $ bin/wasm-interp test.wasm -V 100 --run-all-exports ``` You can use `--help` to get additional help: ```console $ bin/wasm-interp --help ``` ## Running wast2json See [wast2json.md](docs/wast2json.md). ## Running wasm-decompile For example: ```sh # parse binary file test.wasm and write text file test.dcmp $ bin/wasm-decompile test.wasm -o test.dcmp ``` You can use `--help` to get additional help: ```console $ bin/wasm-decompile --help ``` See [decompiler.md](docs/decompiler.md) for more information on the language being generated. ## Running wasm2c See [wasm2c.md](wasm2c/README.md) ## Running the test suite See [test/README.md](test/README.md). ## Sanitizers To build with the [LLVM sanitizers](https://github.com/google/sanitizers), append the sanitizer name to the target: ```console $ make clang-debug-asan $ make clang-debug-msan $ make clang-debug-lsan $ make clang-debug-ubsan ``` There are configurations for the Address Sanitizer (ASAN), Memory Sanitizer (MSAN), Leak Sanitizer (LSAN) and Undefined Behavior Sanitizer (UBSAN). You can read about the behaviors of the sanitizers in the link above, but essentially the Address Sanitizer finds invalid memory accesses (use after free, access out-of-bounds, etc.), Memory Sanitizer finds uses of uninitialized memory, the Leak Sanitizer finds memory leaks, and the Undefined Behavior Sanitizer finds undefined behavior (surprise!). Typically, you'll just want to run all the tests for a given sanitizer: ```console $ make test-asan ``` You can also run the tests for a release build: ```console $ make test-clang-release-asan ... ``` The GitHub actions bots run all of these tests (and more). Before you land a change, you should run them too. One easy way is to use the `test-everything` target: ```console $ make test-everything ``` ## Fuzzing To build using the [LLVM fuzzer support](https://llvm.org/docs/LibFuzzer.html), append `fuzz` to the target: ```console $ make clang-debug-fuzz ``` This will produce a `wasm2wat_fuzz` binary. It can be used to fuzz the binary reader, as well as reproduce fuzzer errors found by [oss-fuzz](https://github.com/google/oss-fuzz/tree/master/projects/wabt). ```console $ out/clang/Debug/fuzz/wasm2wat_fuzz ... ``` See the [libFuzzer documentation](https://llvm.org/docs/LibFuzzer.html) for more information about how to use this tool. ## Installing prebuilt binaries Wabt is available on many platforms as prepackaged binaries. For example, if you use Homebrew you can use: ```sh brew install wabt ``` And you use an apt-based linux distribution you can use: ```sh sudo apt install wabt ``` You can also download prebuilt binaries for many platforms directly from the github releases page. ================================================ FILE: SECURITY.md ================================================ # Security Policy WABT is maintained by volunteers on a reasonable-effort basis. If you have discovered a security vulnerability, please open a GitHub issue to report it. In the future, we may move to a system of private reporting of security issues. Please submit your report by filling out [this form](https://github.com/WebAssembly/wabt/issues/new). Please provide the following information in your report: - A description of the vulnerability and its impact - How to reproduce the issue - Which WABT tools or library functions are affected - Which WebAssembly features (`--enable` flags) must be enabled ================================================ FILE: docs/decompiler.md ================================================ # wasm-decompile Decompiles binary wasm modules into a text format that is significantly more compact and familiar (for users of C-style languages). Example: `bin/wasm-decompile test.wasm -o test.dcmp` ## Goals. This tool is aimed at users that want to be able to "read" large volumes of Wasm code such as language, runtime and tool developers, or any programmers that may not have the source code of the generated wasm available, or are trying to understand what the generated code does. The syntax has been designed to be as light-weight and as readable as possible, while still allowing one to see the underlying Wasm constructs clearly. ## Non-goals. Be a programming language. Though compiling this output code back into a wasm module is possible, such functionality is currently not provided. The format is very low-level, much like Wasm itself, so even though it looks more high level than the .wat format, it wouldn't be any more suitable for general purpose programming. ## Language guide. This section shows some aspects of the language in terms of how they map to Wasm and/or how they might differ from a typical C-like language. It does not try to define the actual semantics of Wasm, the reader is expected to already be mostly familiar with that. ### Naming. wasm-decompile, much like wasm2wat, derives names from the name section (preferrably), or linker symbols (if available), or import/export (if not available in the other 2). For things that have no names, names are generated starting from `a`, `b`, `c` and so forth. In addition, prefixes are used for things that are not arguments/locals: `f_` for functions, `g_` for globals, etc. Existing names may be generated "demangled" C++ function signatures, which in the case of functions using STL types may end up several hundred characters long. Besides removing characters not typically part of an identifier, the decompiler also strips common keywords/types from these in an effort to reduce their size. Linker symbols are typically only available in wasm .o files, though if useful for naming can be retained in fully linked wasm modules using the `--emit-reloc` flag to `wasm.ld`. This gives you names for most functions even when `--strip-debug` was used. ### Top level declarations. Top level items may be preceded with `import` or `export`. Memory is declared like `memory m(initial: 1, max: 0);` Globals: `global my_glob:int;` Data: `data d_a(offset: 0) = "Hello, World!";` Functions (see below for instructions that may appear between `{}`): `function f(a:int, b:int):int { return a + b; }` ### Statements and expressions. An expression is generated for any sequence of Wasm instructions that leave exactly 1 value on the stack. For instructions that leave no value values on the stack, a statement is generated, which is an expression that sits on its own line in the context of a control-flow block, or the function itself. A statement may also be generated for expressions that return a value through control flow, such as a branch instruction. Instructions that leave multiple values on the stack, or otherwise do stack operations that break the "expression order", instead force the values to be written to temporary variables (named `t1`, `t2` etc) which the subsequent instructions can then operate upon (this does not happen with MVP-only code). ### Declaration of arguments and locals. Arguments are defined in the function signature, as shown above. Locals are defined upon first use: `var my_local:int = 1;` ### Types. The decompiler uses `int` and `long` for 32-bit and 64-bit integers, and `float` and `double` for 32-bit and 64-bit floating point numbers. Besides these, there are the types `byte` and `ubyte` (8-bit), `short` and `ushort` (16-bit), and `uint`, which are used exclusively with certain load/store operations. ### Loads and stores. These tend to be the hardest to "read" in Wasm code, as they've lost all context of the data structures and types the language that Wasm was compiled from was operating upon. wasm-decompile has a few features to try and make these more readable. The basic form looks like an array indexing operation, so `o[2]:int` says: read element 2 from `o` when seen as an array of ints. This thus accesses 4 bytes at byte-offset 8. `o` is just declared as an `int`, since there is no such thing as a pointer type in Wasm. But wasm-decompile tries to derive them. For example, if the code is doing `o[0]:int = o[1]:int + o[2]:int`, then wasm-decompile assumes `o` points to a struct with 3 ints, and may instead compile this to: var o:{ a:int, b:int, c:int }; o.a = o.b + o.c The `{}` type is a nameless struct declaration (named ones tbd) that hints the reader at what kind of memory layout `o` is accessing. This seems more informative than just uncorrelated indices all over the code. Sadly, optimized output from a compiler like LLVM often reworks memory accesses in such crazy ways that this "struct detection" fails, for example it falls back to indexing operations when there are holes or overlaps in the memory layout, or types are mixed, etc. This happens even more so when locals such as `o` are being re-used for unrelated things in memory. For accesses that are not contiguous, but at least of the same type, the decompiler will change the pointer type from `o:int` to e.g. `o:float_ptr` (and similarly, it will omit the type from the actual access, `o[2]` instead of `o[2]:int`). Additionally, wasm-decompile tried to clean up typical indexing operations. For example, when accessing any array of 32-bit elements, generated Wasm code often looks like `(base + (index << 2))[0]:int`, since Wasm has no built-in way to scale the index by the type of thing being loaded. wasm-decompile then transforms this into just `base[index]:int`, since the scaling of anything between the `[]` by the type size is already implied. ### Control flow. Wasm's if-then maps fairly directly to a C-like `if (c) { 1; } else { 2; }`. Unlike most languages, these if-thens can also be expressions, as shown in this example (wasm-decompile does not currently use the `?:` ternary). Wasm's loop becomes a `loop L { ...; continue L; }` structure. The inclusion of a label means nested loops can continue any of them. Wasm's blocks are little more than a label for forward jumps, and cause excessive amounts of nesting in other text formats such as .wat, so here they are reduced to what they naturally are: a label. This label uses `{}` for denoting a block only when used as an expression, so typically does not indent, and thus doesn't cause endless nesting: if (c) goto L; ... label L: ### Operator precedence. wasm-decompile uses the following operator precedence to reduce the amount of `()` needed in expressions, from high (needs no `()`) to low (always needs `()` when nested): * `()`, `a`, `1`, `a()` * `[]` * `if () {} else {}` * `*`, `/`, `%` * `+`, `-` * `<<`, `>>` * `==`, `!=`, `<`, `>`, `>=`, `<=` * `&`, `|` * `min`, `max` * `=` Only `+` and `*` are associative, i.e. can have multiple of them in sequence without additional `()`. ================================================ FILE: docs/demo/custom.css ================================================ html { font-size: 80%; line-height: 1.3; } * { box-sizing: border-box; } body { font-family: sans-serif; font-size: 1rem; line-height: 1.3125rem; margin: 0; } h1 { font-size: 2.375rem; line-height: 2.625rem; margin-top: 1.3125rem; margin-bottom: 1.3125rem; } h2 { font-size: 1.75rem; line-height: 2.625rem; margin-top: 1.3125rem; margin-bottom: 1.3125rem; } h3 { font-size: 1.3125rem; line-height: 1.3125rem; margin-top: 1.3125rem; margin-bottom: 0rem; } h4 { font-size: 1rem; line-height: 1.3125rem; margin-top: 1.3125rem; margin-bottom: 0rem; } h5 { font-size: 1rem; line-height: 1.3125rem; margin-top: 1.3125rem; margin-bottom: 0rem; } p, ul { padding-left: 0; margin-top: 0rem; margin-bottom: 1.3125rem; } ul ul, ol ol, ul ol, ol ul { margin-top: 0rem; margin-bottom: 0rem; } pre { margin: 0; } .right { float: right; white-space: nowrap; } .hidden { display: none; } #split-grid { position: absolute; height: 100%; left: 0; right: 0; top: 0; } .CodeMirror, .cm-editor, .output { position: absolute; height: calc(100% - 2.625rem); top: 2.625rem; left: 0; right: 0; } .output { padding: 0.3125rem; overflow: auto; } .toolbar { position: absolute; top: 0; right: 0; left: 0; color: #555; background-color: #eee; z-index: 9; height: 2.625rem; line-height: 2rem; padding: 0.3125rem 0.3125rem 0; box-shadow: 0 2px 2px rgba(0, 0, 0, 0.3); } .split-horizontal, .gutter-horizontal { height: 100%; float: left; } .gutter-horizontal { cursor: ew-resize; background-image: url('assets/vertical.png'); } .gutter-vertical { cursor: ns-resize; background-image: url('assets/horizontal.png'); } .gutter { touch-action: none; user-select: none; background-color: #ddd; background-repeat: no-repeat; background-position: 50%; z-index: 0; } .split { position: relative; overflow: hidden; } body { display: flex; min-height: 100vh; flex-direction: column; } main { flex: 1; position: relative; } header { padding: 0 1em; z-index: 10; box-shadow: 0 2px 2px rgba(0, 0, 0, 0.3); } ul { margin: 1em; list-style: none; } #features { display: flex; flex-wrap: wrap; gap: 8px 16px; margin-top: 0.5rem; margin-bottom: 1rem; } .feature-item { display: flex; align-items: center; gap: 4px; } ================================================ FILE: docs/demo/index.html ================================================ wabt demos

WABT Demo Third-Party Dependencies This directory contains the build configuration for third-party dependencies used by the WABT web demos (located in `docs/demo`). Currently, this is used to generate a single ES Module bundle for **CodeMirror 6**, which is required because CodeMirror 6 consists of many highly-scoped NPM packages that are difficult to load individually via CDNs in a browser without instance-duplication issues. ## Building the Third-Party Bundle The demo applications (`wasm2wat/index.html` and `wat2wasm/index.html`) expect to find a compiled bundle at `docs/demo/third_party.bundle.js`. To regenerate this bundle: 1. Ensure you have [Node.js and npm](https://nodejs.org/) installed. 2. From this directory (`docs/demo/third_party`), execute: ```bash npm install npm run build ``` The `build` script uses `esbuild` to analyze `index.js`, tree-shake the used modules (like `EditorView`, `wast` syntax highlighting, and `javascript` support), and output the final ES Module bundle as `../third_party.bundle.js`. ## Adding or Updating Dependencies 1. If you need to expose new CodeMirror features to the demo apps, add the relevant `export` statement to `index.js`. 2. To update versions of CodeMirror, run `npm update` or manually adjust `package.json` and run `npm install`. 3. Commit both the updated `package.json`/`package-lock.json` and the built `../third_party.bundle.js`. ================================================ FILE: docs/demo/third_party/index.js

FILE: docs/wast2json.md
================================================
# wast2json

`wast2json` converts a `.wast` file to a `.json` file, and a collection of
associated `.wat` file and `.wasm` files.

## Example

```sh
# parse spec-test.wast, and write files to spec-test.json. Modules are written
# to spec-test.0.wasm, spec-test.1.wasm, etc.
$ bin/wast2json spec-test.wast -o spec-test.json
```

## Wast

The wast format is described in the [spec
interpreter](https://github.com/WebAssembly/spec/tree/master/interpreter#scripts).
It is an extension of the `.wat` text format, with additional commands for
running scripts. The syntax is repeated here:

```
script: *

cmd:
                                     ;; define, validate, and initialize module
  ( register  ? )              ;; register module for imports
module with given failure string
                                     ;; perform action and print results
                                  ;; assert result of an action
                                       ;; meta command

module:
  ...
  ( module ? binary * )        ;; module in binary format (may be malformed)
  ( module ? quote * )         ;; module quoted in text (may be malformed)

action:
  ( invoke ?  * )        ;; invoke function export
  ( get ?  )                   ;; get global export

assertion:
  ( assert_return  * )       ;; assert action has expected results
  ( assert_trap   )         ;; assert action traps with given failure string
  ( assert_exhaustion   )   ;; assert action exhausts system resources
  ( assert_malformed   )    ;; assert module cannot be decoded with given failure string
  ( assert_invalid   )      ;; assert module is invalid with given failure string
  ( assert_unlinkable   )   ;; assert module fails to link
  ( assert_trap   )         ;; assert module traps on instantiation

result:
  ( .const  )

numpat:
                                      ;; literal result
  nan:canonical                              ;; NaN in canonical form
  nan:arithmetic                             ;; NaN with 1 in MSB of payload

meta:
  ( script ?
