Yes. The node is defined as:
```
def SDTBrxEndProfile : SDTypeProfile<0, 3, [SDTCisVT<0, OtherVT>, SDTCisInt<1>, SDTCisInt<2>]>;
...
def brx_end :
  SDNode<"NVPTXISD::BrxEnd", SDTBrxEndProfile,
         [SDNPHasChain, SDNPInGlue, SDNPSideEffect]>;
```
That is, it has one result, which is the chain.
