Update of /home/projects/pgsql/cvsroot/pgsql/src/include/storage
     from hub.org:/home/projects/pgsql/tmp/cvs-serv36391

Modified Files:
    s_lock.h

-----------------------------  Log Message  -----------------------------

Clean up spinlock assembly code slightly (just cosmetic improvements)
for Alpha gcc case.  For Alpha non-gcc case, replace use of
__INTERLOCKED_TESTBITSS_QUAD builtin with __LOCK_LONG_RETRY and
__UNLOCK_LONG.  The former does not execute an MB instruction and
therefore was guaranteed not to work on multiprocessor machines.
The LOCK_LONG builtins produce code that is the same in all essential
details as the gcc assembler code.
