@adairrr Could you have a look at the feature compilation?

Run

• make build
• cd tests/simple-contract

docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
abstractmoney/rust-optimizer-arm64:0.14.0

PS: The target directory was changed to /target from ./target in the upstream repo.

Error i'm getting:

error: unexpected argument '--features hello' found

  tip: a similar argument exists: '--features'

Which is some Bash shenanigans I (and chat-gpt) can't seem to figure out...

Wrong repo, sorry!

This is a pretty neat way to create feature-enabled builds without adding extra complexity for the reproducer.

Let me know if it works well for you. Feels like a great candidate for upstreaming.

We've been using it for a while so we know it works. Will see if we can clean it up a bit.
