tree-vectorizer.h (vect_loop_vectorized_call): Declare.
2019-06-13 Richard Biener <rguenther@suse.de>
* tree-vectorizer.h (vect_loop_vectorized_call): Declare.
* tree-vectorizer.c (vect_loop_vectorized_call): Export and
also return the condition stmt.
* tree-vect-loop-manip.c (vect_loop_versioning): Compute outermost
loop we can version and version that, reusing the loop version
created by if-conversion instead of versioning again.
* gcc.dg/vect/vect-version-1.c: New testcase.
* gcc.dg/vect/vect-version-2.c: Likewise.
