From: Kong Lingling <lingling.k...@intel.com>
For *one_cmplsi2_2_zext, it will be splitted to xor, so its NDD form will be
added together with xor NDD support.
gcc/ChangeLog:
* config/i386/i386.md (one_cmpl<mode>2): Add new constraints for NDD
and adjust output template.
(*one_cmpl<mode>2_1): Likewise.
(*one_cmplqi2_1): Likewise.
(*one_cmpl<dwi>2_doubleword): Likewise.
(*one_cmpl<mode>2_2): Likewise.
(*one_cmplsi2_1_zext): Likewise, and use nonimmediate_operand for
operands[1] to accept memory input for NDD alternative.
gcc/testsuite/ChangeLog:
* gcc.target/i386/apx-ndd.c: Add not test.
