This adds except_ref type, which is a part of the exception handling
proposal.

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

BinaryenGlobalImportGetModule (#2047)
|
| |
|
|
|

Adds support for the bulk memory proposal's passive segments. Uses a
new (data passive ...) s-expression syntax to mark sections as
passive.

This renames the following:
- `i32.wait` -> `i32.atomic.wait`
- `i64.wait` -> `i64.atomic.wait`
- `wake` -> `atomic.notify`
to match the spec.

This PR adds
void BinaryenConstGetValueV128(BinaryenExpressionRef expr, uint8_t* out);
to the C-API and uses it in Binaryen.getExpressionInfo in the JS-API.

Bulk memory operations
The only parts missing are the interpreter implementation
and spec tests.

Implement and test the following functionality for SIMD.
- Parsing and printing
- Assembling and disassembling
- Interpretation
- C API
- JS API

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.

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.

From #1665 (a fuzz bug noticed they were not handled in stack.h).
|
| |
|
|
|

This allows using imports in the table.
Fixes #1645
|
| |
|
|
|
|
| |
* code cleanups in wasm-binary: remove an & param, and standardize whitespace
* add some docs for how the relooper handles blocks with no outgoing branches [ci skip]
|

* Initial source map support for C/JS
* Also test getDebugInfoFileName

Followup to #1357. This moves the optimization settings into pass.h, and uses it from there in the various places.
This also splits up huge lines from the tracing code, which put all block children (whose number can be arbitrarily large) on one line. This seems to have caused random errors on the bots, I suspect from overflowing a buffer. Anyhow, it's much more clear to split the lines at a reasonable length.

* Add optimize, shrink level and debug info options to C/JS
* Add instantiate functionality for creating additional unique instances of the API
* Use a workaround when running tests in node
Tests misuse a module as a script by concatenating, so instead of catching this case in the library, catch it there
* Update sieve test
Seems optimized output changed due to running with optimize levels 2/1 now
* Use the options with all pass runners
* Update relooper-fuzz C-API test
* Share defaults between tools and the C-API
* Add a test for optimize levels
* Unify node test support in check.by and auto_update_tests.py
* Also add getters for optimize levels and test them
* Also test debugInfo
* Add debug info to C tests that used it as well
* Fix missing NODEJS import in auto_update_tests
* Detect node.js version (WASM support)
* Update hello-world JS test (now also runs with node)
* feature-test WebAssembly in node instead
* Document that these options apply globally, and where
* Make sure hello-world.js output doesn't differ between mozjs/node

This PR adds global variable support (addGlobal, getGlobal, setGlobal), host operations (currentMemory, growMemory), a few utility functions (removeImport, removeExport, getFunctionTypeBySignature with the latter being scheduled for removal once a better alternative is in place) and it introduces an additional argument to specify the result type in BinaryenBlock (effectively breaking the C-API but retaining previous behaviour by introducing the BinaryenUndefined() type for this purpose). Additionally, it enables compilation with exception support in build-js.sh as exceptions are thrown and caught when optimizing endless loops, intentionally resulting in an unreachable opcode. Affected test cases have been updated accordingly.

New binaryen.js implementation, based on the C API underneath and with a JS-friendly API on top. See docs under docs/ for API details.
