* ppc.h (struct powerpc_operand): Replace "bits" with "bitm".
	(num_powerpc_operands): Declare.
	(PPC_OPERAND_SIGNED et al): Redefine as hex.
	(PPC_OPERAND_PLUS1): Define.
opcodes/
	* ppc-dis.c (print_insn_powerpc): Adjust for struct powerpc_operand
	change.
	* ppc-opc.c (powerpc_operands): Replace bit count with bit mask
	in all entries.  Add PPC_OPERAND_SIGNED to DE entry.  Remove
	references to following deleted functions.
	(insert_bd, extract_bd, insert_dq, extract_dq): Delete.
	(insert_ds, extract_ds, insert_de, extract_de): Delete.
	(insert_des, extract_des, insert_li, extract_li): Delete.
	(insert_nb, insert_rsq, insert_rtq, insert_ev2, extract_ev2): Delete.
	(insert_ev4, extract_ev4, insert_ev8, extract_ev8): Delete.
	(num_powerpc_operands): New constant.
	(XSPRG_MASK): Remove entire SPRG field.
	(powerpc_opcodes <bcctre, bcctrel>): Use XLBB_MASK not XLYBB_MASK.
gas/
	* messages.c (as_internal_value_out_of_range): Extend to report
	errors for values with invalid low bits set.
	* config/tc-ppc.c (ppc_setup_opcodes): Check powerpc_operands bitm
	fields.  Check that operands and opcode fields are disjoint.
	(ppc_insert_operand): Check operands using mask rather than bit
	count.   Check low bits too.  Handle PPC_OPERAND_PLUS1.  Adjust
	insertion code.
	(md_apply_fix): Adjust for struct powerpc_operand change.
