[PATCH] D18069: Throttling LICM to reduce compile time of Value Propagation and Reg Splitting

[Philip Reames via llvm-commits]

reames added a comment.

I understand your thought process, but this approach is just not going to work.  As a matter of policy, we canonicalize at the IR level and LICM is pretty much the classic definition of canonicalization.  Restricting the aggressiveness of LICM to resolve a compile time problem elsewhere in the optimizer is fundamentally unacceptable.
