- No build system. Just a bash script.
- No Emscripten.
- Stripped down to the bare minimum. Every line of code has a purpose.
This repo is Mac only for now.
This builds on a minimal C++/C + libc to WASM template that I recommend to look at if you want to learn how the bare WASM stack works without the additional the complexity. Additional considerations to build llama2.c:
- mmap is not part of the WASI standard but there's an emulation available on the wasi-sdk by passing the
D_WASI_EMULATED_MMANflag to the compiler and linking againstwasi-emulated-mmanlibrary. For this we also need to link againstclang_rt.builtins-wasm32that the wasi-sdk distributes separatetly.
The command below downloads a wasi-sdk release bundle that contains the WASI headers, libraries, compiler (clang) and linker (wasm-ld)
./setup.shCompiles and links C++ code to WASM

/vendor/wasi.js is built from the runno wasi js runtime by running mpm run build. There are two small modifications on 9b9dc1f3142c that I might submit upstream:
- The ability to pass a WebAssembly.Memory object to the runtime.
- The ability to pass an object with JS-defined functions that can be invoked from native code.
I included a wasi.js.original file as a references for the differences (git diff wasi.js wasi.js.original)
