...instruction selection these are replaced by actual, physical, BRCC instructions. This solution has proved to work fine without having to explicitly involve the SR. Of course, the SR is still implicitly involved by the correct definition of ‘Uses’ and ‘Defs’ on the corresponding instructions.

...lowering. I would suggest that you look in more detail at the actual implementation of the ConvertNodeToLibCall and from where it is called and its actual purpose. There’s nothing else required.

I also created my own TargetTransformInfo implementation based on the ARM code, which works fine as the functions get diligently called, but I found that it’s not of much help because it doesn’t have the necessary hooks to solve this issue) So any additional help would be appreciated.
