afonso360 opened PR #5505 from fix-iabs to main:

When lowering iabs, we were accidentally comparing the unextended value, this caused the instruction to misbehave with certain top bits.

This commit also adds a zbb lowering that does not use jumps.

Fixes #5501

Similarly here: we're only handling integer types for what looks like a general-purpose function, let's tighten up the type restriction to use ty_int as well.
