Hello, All.
Currently to do subj, code like this is used:
> while (true)
> {
> AtomicCounter::counter_type old = dbb_flags;
> if ((old & (DBB_sweep_in_progress |
> DBB_sweep_starting)) || (dbb_ast_flags & DBB_shutdown))
> return false;
>
> if (dbb_flags.compareExchange(old, old |
> DBB_sweep_starting))
> break;
> }
Is there a reason not to use _InterlockedOr() intrinsic with MSVC and
__sync_or_and_fetch() with GCC for such cases?
