--- Comment #3 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- As for 'special' regs and their ordering, I'm not sure. I would suggest that if we have a commutative operation with two registers and one of the registers is marked as a pointer, then it should appear first. But other than that, I don't have any other suggestions here.
