It is a regression from 3.3. On 3.3 we don't recognize (symbol_ref "digs") as a constant so CSE decides it isn't worth trying to substitute the problematic equality for (reg 101). It may be possible to construct testcases which trigger similar failures on 3.3, but I can't find any.

Ok for 3.4 given this?

Yes, thanks!
