 General Improvements
 
+
+  The default vectorizer cost model at -O2 has been enhanced
+to handle unknown tripcount. But it still disables vectorization of loops
+when any runtime check for data dependence or alignment is required,
+it also disables vectorization of epilogue loops but otherwise is equal
+to the cheap cost model.
