OK, so that is not it. The problem is that can_assign_to_reg_p() returns true when x is (ashift:HI (reg/v:HI 27 [ n ]) (subreg:QI (reg/v:HI 27 [ n ]) 0)). num_clobbers == 1 but added_clobbers_hard_reg_p returns false. It seems to me that store motion is OK here, but I don't know who is usually responsible for adding the clobbers... Gr. Steven
