re PR middle-end/37908 (atomic NAND op generate wrong code; __sync_nand_and_fetch, __sync_fetch_and_nand)
PR middle-end/37908
* config/alpha/alpha.c (alpha_split_atomic_op): Properly handle NAND
case by calculating ~(new_reg & val) instead of (~new_reg & val).
* config/alpha/sync.md (sync_nand<mode>): Change insn RTX
to (not:I48MODE (and:I48MODE (...))).
(sync_old_nand<mode>): Ditto.
(sync_new_nand<mode>): Ditto.
