Subject: Work around MSVC bug in IntrusiveRefCntPtr.h
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=be5c5d77573e97abff427216a806d0bd53e291df;p=oota-llvm.git

Work around MSVC bug in IntrusiveRefCntPtr.h

The build was failing with:

  error C2664: 'std::atomic_int::atomic_int(const std::atomic_int &)' : cannot convert argument 1 from 'int' to 'const std::atomic_int &'

Apparently "std::atomic_int x(0)" doesn't work, but "std::atomic<int> x(0)"
does.
