I must admit I haven't. I'm guessing you mean specifically for doing that in combination with lit?

If it's just this one variable that's undecided at compile time, I think we can work around this. Lit itself supports you to pass variables with the `-D` prefix, which could be used to pass a different compiler to dotest. The wrapper itself would just forward that argument. I assume there is (and if there isn't it's trivial to add) support for overwriting the compiler?
