* Update cranelift to 0.58.0 * Update `wasmprinter` dep to require 0.2.1 We already had it in the lock file, but this ensures we won't ever go back down. * Ensure that our error messages match `assert_invalid`'s The bulk of this work was done in https://github.com/bytecodealliance/wasmparser/pull/186 but now we can test it at the `wasmtime` level as well. Fixes #492 * Stop feeling guilty about not matching `assert_malformed` messages Remove the "TODO" and stop printing warning messages. These would just be busy work to implement, and getting all the messages the exact same relies on using the same structure as the spec interpreter's parser, which means that where you have a helper function and they don't, then things go wrong, and vice versa. Not worth it. Fixes #492 * Enable (but ignore) the reference-types proposal tests * Match test suite directly, instead of roundabout starts/endswith * Enable (but ignore) bulk memory operations proposal test suite
Fuzzing Infrastructure for Wasmtime
This crate provides test case generators and oracles for use with fuzzing.
These generators and oracles are generally independent of the fuzzing engine
that might be using them and driving the whole fuzzing process (e.g. libFuzzer
or AFL). As such, this crate does not contain any actual fuzz targets
itself. Those are generally just a couple lines of glue code that plug raw input
from (for example) libFuzzer into a generator, and then run one or more
oracles on the generated test case.
If you're looking for the actual fuzz target definitions we currently have, they
live in wasmtime/fuzz/fuzz_targets/* and are driven by cargo fuzz and
libFuzzer.
