[PATCH] D52807: [COFF, ARM64] Add _InterlockedCompareExchangePointer_nf intrinsic

[Reid Kleckner via Phabricator via cfe-commits]

rnk added inline comments.


================
Comment at: lib/CodeGen/CGBuiltin.cpp:3003
+  case Builtin::BI_InterlockedCompareExchangePointer:
+  case Builtin::BI_InterlockedCompareExchangePointer_nf: {
     llvm::Type *RTy;
----------------
Is the no fence version really equivalent to this seq_cst version here?
