After receiving some good feedback from reddit I have added the ability to compare the AMD IL that is generated by the driver. Here is the updated download.

Showing the comparison between the generated DirectX ASM and AMD IL for PS_5_0

This is done by calling the AMD program CodeXLAnalyser.exe to generate it. This .exe is in the same directory as "Shader Analyzer.exe" so if in the future AMD updates that you can just swap out the .exe. I have also added a control on the dialog to specify any AMD IL command line arguments which can be found at the AMD developer site here. However, the information there is either not complete or out of date so I have included a screenshot of the full output of the help command below.
