[PATCH] D86586: [TableGen] Support tied operands that are both source operands

[Brian Leibig via Phabricator via llvm-commits]

bleibig added a comment.

I'm not sure why the checks were initially added, whether it is because the tied operand system is designed only for use and def tied operands and won't work in any other way without major changes, or just because there hasn't been a use case yet for two tied source operands. Either way, I feel the changes I have so far may be insufficient to solve this, so any feedback for further changes would be greatly appreciated.
