It appears that you're restricting operands1 to be a REG/SUBREG, if that's what your intention is, then changing the operand predicate seems to be a better solution. Furthermore, you'd need to explain why restricting operand1 to be a REG/SUBREG is the right thing to do. It'd also be helpful to know why this problem does not occur on the trunk or gcc-4.6 branches, which appear to have the same code as the gcc-4.5 branch for the peephole.
