Comparing clang-12 against clang-11, without LTO. An improvement is visible. Hopefully, not because of the code layout. ``` fizzy/parse/blake2b_mean +0.0103 +0.0103 25 25 25 25 fizzy/instantiate/blake2b_mean -0.0129 -0.0129 31 31...

Parser and validation design

## Levels of parsing / decoding / validation 0. "Unsafe" parser. It assumes the wasm module must be valid and happily reads it without checkout out-of-buffer access. Providing invalid module...

Nice function execution API

I think using methods instead of free function may be nicer and will be more JavaScript-like. In particular, for function execution we may have something like: ```cpp auto instance =...

Dump all inputs for `fizzy::parse()` to a directory to be used as fuzzing corpus.

Optimize uint256 multiplication

1. We want to use the "loop" procedure as in `mul_loop_opt()`. 2. There, it may be good to separate first iteration which does not need to load `p[]` values as...
