GCC maintainers: I have addressed the comments to the five patches in the series that have not yet been approved. The patches that have already been approved are 1, 3, 5, 6, 8, 9, 10, and 12.
The remaining patches all have fairly minor fixes requested. I will just post version 4 of these patches here. The goal is to commit the entire series all at once as they are all related. So I a holding off committing the approved patches. Thank you for your time and feedback of these patches. The entire patch series has been tested on Power 10 LE, Power 9 BE with no regression failures. Carl
