[PATCH] D48326: [RFC] "Alternative" matches for TableGen DAG patterns

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

I don't think that the new keyword is necessary.  Why not have a new class `Patterns`that takes a list of input dag patterns (otherwise identical to the current `Pattern`), and matches when any of these inputs matches?  Then you can have a `PatFrags` as an analogy to `PatFrag`.
