jameysharp opened PR #5642 from no-preopt to main:

Most of these optimizations are in the egraph cprop.isle rules now, making a separate crate unnecessary.

Also I think the udiv optimizations here are straight-up wrong (doing signed instead of unsigned division, and panicking instead of preserving traps on division by zero) so I'm guessing this crate isn't seriously used anywhere.

At the least, bjorn3 confirms that cg_clif doesn't use this, and I've verified that Wasmtime doesn't either.

Closes #1090.
