- Loop Vectorizer
- ---------------
- We've continued the work on the loop vectorizer. The loop vectorizer now has the following features:
-  # Loops with unknown trip count.
-  # Runtime checks of pointers
-  # Reductions, Inductions
-  # If Conversion
-  # Pointer induction variables
-  # Reverse iterators
-  # Vectorization of mixed types
-  # Vectorization of function calls
-  # Partial unrolling during vectorization
+* TargetTransformInfo (TTI) is a new interface that can be used by IR-level
+  passes to obtain target-specific information, such as the costs of
+  instructions. Only "Lowering" passes such as LSR and the vectorizer are
+  allowed to use the TTI infrastructure.
 
-  We've also improved the X86 and ARM cost model.
