		const CallExpr *	E,
		bool	ReturnBool,

		llvm::SyncScope::ID	SSID )

Utility to insert an atomic cmpxchg instruction.

Parameters

CGF	The current codegen function.
E	Builtin call expression to convert to cmpxchg. arg0 - address to operate on arg1 - value to compare with arg2 - new value
ReturnBool	Specifies whether to return success flag of cmpxchg result or the old value.

Returns

result of cmpxchg, according to ReturnBool

Note: In order to lower Microsoft's _InterlockedCompareExchange* intrinsics invoke the function EmitAtomicCmpXchgForMSIntrin.
