I've updated the patch to handle that. Bootstrap and regression > testing is in progress again. While this was bootstrapping, I started playing around with different opt levels with the test case. It seems if I use -fno-gcse, then we again fail to order the operands correctly. So it, looks like there's another location that needs updating to copy the REG_POINTER attribute. I'll post another patch when I've found it. Peter
