2019-12-05  Jozef Lawrynowicz  <jozef.l@mittosystems.com>

	* config/msp430/msp430.md (cbranch<mode>4): Use
	msp430_general_dst_nonv_operand instead of nonimmediate_operand for
	dest operand of CMP instruction.
	(cbranchpsi4_real): Likewise.
	(cbranchqi4_real): Likewise.
	(cbranchhi4_real): Likewise.
	(cbranchpsi4_reversed): Likewise.
	(cbranchqi4_reversed): Likewise.
	(cbranchhi4_reversed): Likewise.
