PR middle-end/37908
* optabs.c (expand_sync_operation): Properly handle NAND case
by calculating ~(t1 & val) instead of (~t1 & val).
* builtins.c (expand_builtin_sync_operation): Warn for changed
semantics in NAND builtins.
* c.opt (Wsync-nand): New warning option. Describe -Wsync-nand.
* doc/invoke.texi (Warning options): Add Wsync-nand.
* doc/extend.texi (Atomic Builtins) [__sync_fetch_and_nand]: Correct
__sync_fetch_and_nand builtin operation in the example. Add a note
about changed semantics in GCC 4.4.
[__sync_nand_and_fetch]: Correct __sync_nand_and_fetch builtin
operation in the example. Add a note about changed semantics in
GCC 4.4.

PR middle-end/37908
* gcc.dg/pr37908.c: New test.
* gcc.dg/ia64-sync-1.c: Correct __sync_fetch_and_nand and
__sync_nand_and_fetch results. Add dg-message to look for the warning
about changed semantics of NAND builtin.
(init_si, init_di): Change init value for __sync_fetch_and_nand to -1.
(test_si, test_di): Change expected result of
__sync_nand_and_fetch to ~7.
* gcc.dg/ia64-sync-2.c: Correct __sync_fetch_and_nand and
__sync_nand_and_fetch results. Add dg-message to look for the warning
about changed semantics of NAND builtin.
(init_noret_si, init_noret_di): Change init value for
__sync_fetch_and_nand to -1.
(init_noret_si, init_noret_di): Change expected result of
__sync_nand_and_fetch to ~7.
* gcc.dg/sync-2.c: Correct __sync_fetch_and_nand and
__sync_nand_and_fetch results. Add dg-message to look for the warning
about changed semantics of NAND builtin.
(init_qi, init_qi): Change init value for __sync_fetch_and_nand to -1.
(init_hi, init_hi): Change expected result of
__sync_nand_and_fetch to ~7.
* gcc.dg/sync-3.c: Copy from sync-2.c instead of including
the c source file.
* gcc.c-torture/compile/sync-1.c: Add dg-message to look for the
warning about changed semantics of NAND builtin.
* gcc.c-torture/compile/sync-2.c: Ditto.
* gcc.c-torture/compile/sync-3.c: Ditto.
