  Because my movsi3 pattern that allows both GENERAL_REGS through an 'r'
constraint, and MPD_REG and MPRL_REG through custom constraint letters ('a'

something wrong?

Adding the union classes would certainly help. The mips port for instance has union classes for hi, lo, the general regs, along with some others. -- Jim Wilson, GNU Tools Support, http://www.specifix.com
