1 ; This test is designed to run three times, once with function attributes, once
2 ; with all target attributes added on the command line, and once with compress
3 ; added with the command line and float added via function attributes, all
4 ; three of these should result in the same output.

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