The existing definition using register class CC_REG does not work because CC_REGNUM does not support normal modes, and so fails to match register_operand. Use a non-register constraint and the cc_register predicate instead. * config/arm/constraints.md (c): Use cc_register predicate. --- gcc/config/arm/constraints.md | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
