From 9ddb318f9c45f115b4e59c9a61e721c421953098 Mon Sep 17 00:00:00 2001 From: Emmett Neyman Date: Thu, 9 Aug 2018 00:58:23 +0000 Subject: [PATCH] Added another optimization pass to make vectorizing possible Summary: I noticed that my code wasn't going deep into the loop vectorizer code so added another pass that makes it go further.
