ports: try re-implementing stdlib crypto in avo #56

Open mmcloughlin opened 5 years ago

mmcloughlin commented 5 years ago

The standard library contains some massive crypto assembly files. It would be an interesting exercise to port these to avo, to see if we could improve readability. That said, some of these would be highly non-trivial projects.

$ find src -name '*_amd64.s' | xargs wc -l | sort -n | tail
     743 src/runtime/sys_darwin_amd64.s
    1031 src/crypto/sha256/sha256block_amd64.s

Note this is from Go version:

Is this issue still relevant, with the work that Filippo has been putting in?

mmcloughlin commented 3 years ago

Filippo's work definitely contributes to this, and it's really exciting, but there's still a lot of crypto assembly to address (with avo or otherwise).
