[dependabot]

Bumps wasmi from 0.40.0 to 0.50.0.

Release notes

Sourced from wasmi's releases.

v0.50.0 - 2025-08-11

This is supposedly the final release before Wasmi 1.0.0.

Added

• This version ships with an entirely new Wasm bytecode to Wasmi bytecode translator.
  • The new translator is ~5-10% faster than the old one.
  • Fuel-metering is no longer an afterthought and thus comes nearly for free.
  • The new codebase is much simpler to maintain and reason about.
  • Wasmi bytecode generated by the new translator shows similar performance as the old one.
  • The new translator provides a lot more information to Wasmi's optimizer which allows for new optimizations in upcoming Wasmi releases.
  • PRs: #1512 #1618
• Add lowerings for xor instructions when used in comparisons.
  • This reduced the number of Wasmi bytecode instructions by a whopping 20 which might have positive effects on execution performance due to decreased cache pressure.
  • PRs: #1625

Changed

• Removed Wasmi bytecode instructions that are no longer generated by the new translator.
  • This also reduces the number of Wasmi bytecode instructions by 8 which might have positive effects on execution performance due to decreased cache pressure.
  • PRs: #1623 #1624

Internal

• Remove some Wasmi dependencies.
  • Namely, smallvec, multi-stash and arrayvec.
  • PRs: #1620 #1626
