[PATCH] D30247: Epilog loop vectorization

[Ashutosh Nema via Phabricator via llvm-commits]

ashutosh.nema updated this revision to Diff 90657.
ashutosh.nema added a comment.

This change includes:

a) Code refactoring.

b) Removed call to loop vectorizer’s legality before widening epilog loop as legality is already proven for scalar loop while generating first vector version, it’s not required to prove again as scalar body has not changed. Epilog vectorization will depend on already computed legality.

c) Added tests.
