A fuzz bug came in last night from #5567 where spectest fuzzing will first generate a config, possibly with SSE features for SIMD disabled, only to have SIMD later enabled by `set_spectest_compliant`. This commit fixes the issue by changing to `is_spectest_compliant` as a query and throwing out the fuzz case if it isn't. This means that the spectest fuzzer will throw out more inputs but means we can continue to generate interesting configs and such for other inputs.
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.
