[llvm-dev] TableGen enhancements

[Paul C. Anagnostopoulos via llvm-dev]

It's interesting that you bring this up. I've seen a lot of TableGen error messages over the past couple of weeks and I don't recall being confused about any error or its location. I will give this a closer look.

I agree that syntactic enhancements aren't particularly exciting by themselves. I was wondering whether some new features coupled with new backends would pave the way for additional uses for TableGen in the area of code generation (or any other areas, for that matter).
