This patch implements, for aarch64, the following wasm SIMD extensions i32x4.dot_i16x8_s instruction https://github.com/WebAssembly/simd/pull/127 It also updates dependencies as follows, in order that the new instruction can be parsed, decoded, etc: wat to 1.0.27 wast to 26.0.1 wasmparser to 0.65.0 wasmprinter to 0.2.12 The changes are straightforward: * new CLIF instruction `widening_pairwise_dot_product_s` * translation from wasm into `widening_pairwise_dot_product_s` * new AArch64 instructions `smull`, `smull2` (part of the `VecRRR` group) * translation from `widening_pairwise_dot_product_s` to `smull ; smull2 ; addv` There is no testcase in this commit, because that is a separate repo. The implementation has been tested, nevertheless.
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.
