; 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.
