Thanks all who offered their suggestions.

I'm still working on this issue but may simply use vim eventually.

In that case, you would have to add the TableGen runs to the project as

custom build steps (I forget what they are called in Eclipse), so the generated

include files exist. Then point Eclipse to the correct directory, and it should

pick them up.

Hope that helps,
