._slp patterns should be written in this way, e.g. *and<mode>_1_slp:
(define_insn "*and<mode>_1_slp"
[(set (strict_low_part (match_operand:SWI12 0 "register_operand" "+<r>"))
(and:SWI12 (match_operand:SWI12 1 "nonimmediate_operand" "%0")
(match_operand:SWI12 2 "general_operand" "<r>mn")))
(clobber (reg:CC FLAGS_REG))]
"(!TARGET_PARTIAL_REG_STALL || optimize_function_for_size_p (cfun))
/* FIXME: without this LRA can't reload this pattern, see PR82524. */
&& (rtx_equal_p (operands[0], operands[1])
|| rtx_equal_p (operands[0], operands[2]))"
"and{<imodesuffix>}\t{%2, %0|%0, %2}"
[(set_attr "type" "alu")
(set_attr "mode" "<MODE>")])
The above pattern handles QImode, as well as HImode.
