I have a branch of https://github.com/tpruvot/cpuminer-multi https://github.com/tpruvot/cpuminer-multi, which I am working on tidying up and pushing to Github. It has a bash script that instead of GCC / Clang, compiles to WASM. Any Clang compilable software can compile to WASM theoretically. Only supports cryptonight hashing at the moment.
