[LLVMdev] MCELFStreamer subclassing

[Jim Grosbach]

Hi Jack,

Can you elaborate a bit on what you're trying to do? Relocations are handled by the ObjectWriter interfaces, not by the streamer. The <ObjectFormat>Streamer classes aren't intended to be subclassed by targets.

My first thought is always that I am doing something wrong and that may still be the issue, but it is suspicious that no one has subclassed MCELFStreamer yet.
