Andrew Brown 0c7885cc05 fuzz: improve wasm-spec-interpreter documentation, add library path (#4007) 
The documentation for the `wasm-spec-interpreter` was not up-to-date,
causing some confusion on non-Ubuntu machines. This change adds the
correct dependencies to install and includes the `libgmp` path for
Fedora by default (i.e., `/lib64`).

Raw Blame History

This directory contains the necessary parts for building a library with FFI access to the Wasm spec interpreter. Its major parts:

  • spec: the Wasm spec code as a Git submodule (you may need to retrieve it: git clone -b wasmtime_fuzzing https://github.com/conrad-watt/spec).
  • interpret.ml: a shim layer for calling the Wasm spec code and exposing it for FFI access
  • Makefile: the steps for gluing these pieces together into a static library

Note: the Makefile must be configured with the path to libgmp.a; see LIBGMP_PATHS in the Makefile (Ubuntu: libgmp-dev, Fedora: gmp-static).
