This exposed a missing exception check in parseWebAssemblyModule(),
which could throw but still return a normal completion (which currently
works as we check VM::exception() at the right point, but breaks when
moving everything to exceptions).

This method will eventually be removed once all native functions are
converted to ThrowCompletionOr
|
|
The old versions were renamed to JS_DECLARE_OLD_NATIVE_FUNCTION and
JS_DEFINE_OLD_NATIVE_FUNCTION, and will be eventually removed once all
native functions were converted to the new format.
|

|
Also update get_function_name() to use ThrowCompletionOr, but this is
not a standard AO and should be refactored out of existence eventually.

Some i64 values will not fit in normal doubles, and these values _are_
tested by the test suite, this makes the test runtime capable of
handling them correctly.
|

|
...and enable it for LibWeb and test-wasm.
Note that `wasm` will not be limited by this.

This reverts commit 35394dbfaa23b44a293da85b20a63a10f73572c3.
I pushed the wrong button again, hopefully this will be the last of
such incidents.

* wasm: Don't try to print the function results if it traps
* LibWasm: Inline some very hot functions
These are mostly pretty small functions too, and they were about ~10%
of runtime.
* LibWasm+Everywhere: Make the instruction count limit configurable
...and enable it for LibWeb and test-wasm.
Note that `wasm` will not be limited by this.
* LibWasm: Remove a useless use of ScopeGuard
There are no multiple exit paths in that function, so we can just put
the ending logic right at the end of the function instead.

These are usually incorrect, and people sometimes forget to add the
correct values as a result of them being optional, so they should just
be specified explicitly.
|

|
|
This makes debugging wasm code a bit easier, as we now know what fails
instead of just "too bad, something went wrong".
|
|
This commit makes the linking tests in the wasm spec test run.
|
|
This adds component declarations so that users can select to not build
certain parts of the OS.
|
|
|
|
This commit is a fairly large refactor, mainly because it unified the
two different ways that existed to represent references.
Now Reference values are also a kind of value.
It also implements a printer for values/references instead of copying
the implementation everywhere.
|
|
Also makes normal arithmetic operations more spec-compliant by actually
ignoring overflow on them.
|
|
|
|
Managing the instantiated modules becomes a pain if they're on the
stack, since an instantiated module will eventually reference itself.
To make using this simpler, just avoid copying the instance.
|
|
This fixes a FIXME and will allow linking only select modules together,
instead of linking every instantiated module into a big mess of exported
entities :P
|
|
This also optionally generates a test suite from the WebAssembly
testsuite, which can be enabled via passing `INCLUDE_WASM_SPEC_TESTS`
to cmake, which will generate test-wasm-compatible tests and the
required fixtures.
The generated directories are excluded from git since there's no point
in committing them.

This only tests "can it be parsed", but the goal of this commit is to
provide a test framework that can be built upon :)
The conformance tests are downloaded, compiled* and installed only if
the INCLUDE_WASM_SPEC_TESTS cmake option is enabled.
(*) Since we do not yet have a wast parser, the compilation is delegated
to an external tool from binaryen, `wasm-as`, which is required for the
test suite download/install to succeed.
This *does* run the tests in CI, but it currently does not include the
spec conformance tests.
