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

; 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.
