I haven't mentioned that I am using gcc 4.6 latest version.
To generalize the question. If I use an operand like lc_operand
(below) and leave the constraint open, is it guaranteed that the
register that would be chosen would be of class lc?

Hi All,
If I don't use a constraint, is it possible that during ira I get a

In my port I have the following to support HW loops:
(define_predicate lc_operand
(match_operand 0 register_operand)

unsigned
generate an output reload from an
lc_register to either a general register or memory. The predicates
and constraints have to accept all allocatable registers for SImode
and at least (mem (reg)).
See the MeP port for one example of how to do this.
