-> **Note**: The WALI ABI is similar to default Clang wasm32 ABIs but *not identical*. The primary difference is 64-bit `long` types as opposed to 32-bit for wasm32. This is required to mantain minimum source code changes for 64-bit host platforms currently supported. This may change in the future as the spec evolves.

 ### Execution
 Running generated WALI binaries also requires a supported compliant engine implementation -- a working implementation in the [WebAssembly Micro-Runtime (WAMR)](https://github.com/arjunr2/WALI) is included in the repo.

 The `-Zrandomize-layout` flag changes the layout algorithm for `repr(Rust)` types defined in the current crate from its normal
 optimization goals to pseudorandomly rearranging fields within the degrees of freedom provided by the largely unspecified
 default representation. This also affects type sizes and padding.
