[LLVMdev] Where can I find an explanation of $src1, $src2, $in, $ptr, etc.?

I have read through the TableGen Fundamentals documentation and been
browsing various .td files. One thing that is not clear to me is where
things like $src1 (as in GR32:$src1) are defined, and what they mean. The
TableGen Fundamentals page seems silent on this, and I have not found other
documentation that explains it. Browsing through the .td files has not
helped, either (although that has been quite useful to clarify things that
are not spelled out in detail on the TableGen Fundamentals page).

Thanks,

Mark
