(*aarch64__reg_3_neg_mask2): ... this. If pseudos can't be created, use lowpart_subreg of operands[0] rather than operands[0] itself. (*aarch64_reg_3_minus_mask): Rename to ... (*aarch64_ashl_reg_3_minus_mask): ... this. (*aarch64__reg_di3_mask2): Use const_int_operand predicate and n constraint instead of aarch64_shift_imm_di and Usd. (*aarch64_reg__minus3): Rename to ... (*aarch64__reg_minus3): ... this. * gcc.c-torture/compile/pr84845.c: New test.
