2019-12-20   Michael Meissner  <meissner@linux.ibm.com>

	* config/rs6000/predicates.md (cint34_operand): Use
	SIGNED_INTEGER_34BIT_P macro.
	* config/rs6000/rs6000.c (num_insns_constant_gpr): Use the
	SIGNED_INTEGER_16BIT_P and SIGNED_INTEGER_34BIT_P macros.
	(address_to_insn_form): Use the SIGNED_INTEGER_16BIT_P and
	SIGNED_INTEGER_34BIT_P macros.
	* config/rs6000/rs6000.h (SIGNED_INTEGER_NBIT_P): New macro.
	(SIGNED_INTEGER_16BIT_P): Rename SIGNED_16BIT_OFFSET_P to be
	SIGNED_INTEGER_34BIT_P.
	(SIGNED_INTEGER_34BIT_P): Rename SIGNED_34BIT_OFFSET_P to be
	SIGNED_INTEGER_34BIT_P.
