[PATCH] D154594: Add version comparison in BooleanExpression for lit testing

[Louis Dionne via Phabricator via llvm-commits]

ldionne added a comment.

Something like this would be extremely useful in the libc++ test suite! However, IMO it would be a lot more useful if we could:

1. Expand substitutions in these expressions (do we do that?)
2. Do string matching as well. That way I could do something like `REQUIRES: %{stdlib} == libcxx`. I wouldn't actually do that exactly, but you get the point.

In fact, after that, I don't think we need the `available_versions` part of the config anymore. You just add a substitution like `%{a-version}` and then you just have to check for `%{a-version} > 4`. WDYT?
