------- Comment #8 from jakub at gcc dot gnu dot org 2010-06-24 10:57 -------
The cas/casx insns only allow (mem (reg)) addressing:
(match_operand:I48MODE 1 "memory_reg_operand" "+m")
(match_operand:DI 1 "memory_reg_operand" "+m")
The memory_reg_operand predicate checks this and fails if it is not a memory
with a single reg, but apparently there is no constraint letter that would
require the same. So, either we need to add a new constraint letter for memory
that satisfies memory_reg_operand, or find out why predicate hasn't been
consulted.
