Alex Crichton	0642e62f16	Use wasm-smith to canonicalize NaN in differential fuzzing (#3195) ... * Update wasm-smith to 0.7.0 * Canonicalize NaN with wasm-smith for differential fuzzing This then also enables floating point executing in wasmi in addition to the spec interpreter. With NaN canonicalization at the wasm level this means that we should be producing deterministic results between Wasmtime and these alternative implementations.	2021-08-17 11:42:22 -05:00

Andrew Brown	651a321f1a	fuzz: add differential_spec fuzzing target ... This new target compares the outputs of executing the first exported function of a Wasm module in Wasmtime and in the official Wasm spec interpreter (using the `wasm-spec-interpreter` crate). This is an initial step towards more fully-featured fuzzing (e.g. compare memories, add `v128`, add references, add other proposals, etc.)	2021-08-10 11:56:07 -07:00
