WASM Support?

[johnbotris]

Would it be possible to add support for compiling to WebAssembly with emcc for usage as a client puzzle in web applications (assuming that would be an appropriate use of equix)?

I'm currently unable to build due __builtin___clear_cache in HashX compiler_a64.c being unsupported by wasm - If there is another way around this that would be good to know as well

Should be fixed in tevador/hashx@69de17c, which is also applied to the master branch of this repository.

However, if you compile EquiX for WASM, it will only run in the interpreted mode, which is very slow and unsuitable as a client puzzle.

I'm thinking to implement a JIT compiler from HashX code into WASM bytecode, which can be dynamically loaded at runtime. That should make the puzzle much more suitable for browsers.

As the developer of RandomX.js, I could be suited to implement this. I already have code for SuperscalarHash, along with JIT infrastructure.

If there are people who would want this, let me know and I will take time to reimplement the library.

EquiX would be very suitable for use as an ASIC-resistant PoW captcha algorithm. +1 for WASM support
