  stpq R1,D2(X2,B2) operand R1 must designate an even-odd pair of general
registers and must designate an even-numbered register; otherwise, a
specification exception is recognized. [1]

     https://www.ibm.com/docs/en/module_1678991624569/pdf/SA22-7832-14.pdf

opcodes/
	* s390-opc.txt (stpq): Use RXE_RERRD and RXY_RERRD instruction
	formats.

gas/testsuite/
	* gas/s390/zarch-z900.d (stpq): Operand R1 must designate an
	even-odd register pair.
	* gas/s390/zarch-z900.s (stpq): Likewise.
