>   This happens too late for the CTR usability test to veto using the CTR in a loop, and results in an assert "Invalid PPC CTR loop!".

This means after not hoisting `fmul` makes a case have "Invalid PPC CTR loop!" assertion? This is a little surprised for me. Hoist or not hoist `fmul` should not impact CTR register.
Looking forward to your case.
