wasmer/spectests/README.md

This directory contains tests for the core WebAssembly semantics, as described in [Semantics.md](https://github.com/WebAssembly/design/blob/master/Semantics.md) and specified by the [spec interpreter](https://github.com/WebAssembly/spec/blob/master/interpreter/spec).

This files should be a direct copy of the original [WebAssembly spec tests](https://github.com/WebAssembly/spec/tree/master/test/core).

Tests are written in the [S-Expression script format](https://github.com/WebAssembly/spec/blob/master/interpreter/README.md#s-expression-syntax) defined by the interpreter.

## Autogenerated Rust test cases

This files will serve as base for autogenerating Rust testcases
when `WASM_GENERATE_SPECTESTS=1 cargo build` is executed
([src/build_spectests.rs](https://github.com/WAFoundation/wasmer/blob/master/src/build_spectests.rs)).

The result autogenerated spectests live in the [src/spectests](https://github.com/WAFoundation/wasmer/tree/master/src/spectests)
directory.
