* feat: implement memory.atomic.notify,wait32,wait64 Added the parking_spot crate, which provides the needed registry for the operations. Signed-off-by: Harald Hoyer <harald@profian.com> * fix: change trap message for HeapMisaligned The threads spec test wants "unaligned atomic" instead of "misaligned memory access". Signed-off-by: Harald Hoyer <harald@profian.com> * tests: add test for atomic wait on non-shared memory Signed-off-by: Harald Hoyer <harald@profian.com> * tests: add tests/spec_testsuite/proposals/threads without pooling and reference types. Also "shared_memory" is added to the "spectest" interface. Signed-off-by: Harald Hoyer <harald@profian.com> * tests: add atomics_notify.wast checking that notify with 0 waiters returns 0 on shared and non-shared memory. Signed-off-by: Harald Hoyer <harald@profian.com> * tests: add tests for atomic wait on shared memory - return 2 - timeout for 0 - return 2 - timeout for 1000ns - return 1 - invalid value Signed-off-by: Harald Hoyer <harald@profian.com> * fixup! feat: implement memory.atomic.notify,wait32,wait64 Signed-off-by: Harald Hoyer <harald@profian.com> * fixup! feat: implement memory.atomic.notify,wait32,wait64 Signed-off-by: Harald Hoyer <harald@profian.com> Signed-off-by: Harald Hoyer <harald@profian.com>
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.
