- Added a filetest for the vcode output of lowering every handled FP opcode.
- Fixed two bugs that were discovered while going through the lowerings:
- Saturating FP->int operators would return `u{32,64}::MIN` rather than
`0` for a NaN input.
- `fcopysign` did not mask off the sign bit of the value whose sign is
overwritten.
These probably would have been caught by Wasm conformance tests soon
(and the validity of these lowerings will ultimately be tested this way)
but let's get them right by inspection, too!
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
