This won't work because passes can put a hard register in the operands: in the testcase, combine likes to forward the parameter registers to what then is still an smin, and then split1 uses "*s3_fpr" (which has gpc_reg_operand). And then we have a GPR in the operand, which does not match fpr_reg_operand. It seems to me the predicates should be gpc_reg_operand here as well. This patch changes that.
