EmitAtomicCmpXchgForMSIntrin()

Value * EmitAtomicCmpXchgForMSIntrin ( CodeGenFunction & CGF, const CallExpr * E, AtomicOrdering SuccessOrdering = AtomicOrdering::SequentiallyConsistent )

static

This function should be invoked to emit atomic cmpxchg for Microsoft's _InterlockedCompareExchange* intrinsics which have the following signature: T _InterlockedCompareExchange(T volatile *Destination, T Exchange, T Comparand);.

Whereas the llvm 'cmpxchg' instruction has the following syntax: cmpxchg *Destination, Comparand, Exchange. So we need to swap Comparand and Exchange when invoking CreateAtomicCmpXchg. That is the reason we could not use the above utility function MakeAtomicCmpXchgValue since it expects the arguments to be already swapped.

These intrinsics take a pointer to an array of bits and a bit position and read and optionally modify the bit at that position. The position index can be arbitrarily large, i.e. it can be larger than 31 or 63, so we need an indexed load in the general case.
