[PATCH] D18066: Add some shortcuts in Value Propagation for alloca

[Philip Reames via llvm-commits]

reames added a comment.

I just checked in a change which may greatly accelerate LVI for the comparison against null case.  Can you check to see if after "267642: [LVI] Reduce compile time by lazily scanning blocks if needed." you're still seeing compile time problems?

The not-constant bypass might still be needed.  I'm not entirely sure.
