Chandler Carruth 33b200ad13 Tweak the loop rotation logic to check whether the loop is naturally ... laid out in a form with a fallthrough into the header and a fallthrough out of the bottom. In that case, leave the loop alone because any rotation will introduce unnecessary branches. If either side looks like it will require an explicit branch, then the rotation won't add any, do it to ensure the branch occurs outside of the loop (if possible) and maximize the benefit of the fallthrough in the bottom. llvm-svn: 154806		2012-04-16 09:31:23 +00:00
