There are two reasons for this change: 1. it reduces confusion; using the `POR` encoding will match the future encodings of `band` and `bxor` and the `ORPS` encoding may be confusing as it is intended for floating-point operations 2. `POR` has slightly more throughput: it only has to wait 0.33 cycles to execute again on all Intel architectures above Core whereas `ORPS` must wait 1 cycle on architectures older than Skylake (Intel Optimization Reference Manual, C.3) `POR` does add one additional byte to the encoding and requires SSE2 so the `ORPS` opcode is left in for future use.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
