| ; This acts as a basic correctness check for the codegen instruction compression
 | |
| ; path, verifying that the assembled file contains compressed instructions when
 | |
| ; expected. Handling of the compressed ISA is implemented so the same
 | |
| ; transformation patterns should be used whether compressing an input .s file or
 | |
| ; compressing codegen output. This file contains basic functionality tests using
 | |
| ; instructions which also require one of the floating point extensions.
