Renato Golin 35b114fe18 Small refactor on VectorizerHint for deduplication ... Previously, the hint mechanism relied on clean up passes to remove redundant metadata, which still showed up if running opt at low levels of optimization. That also has shown that multiple nodes of the same type, but with different values could still coexist, even if temporary, and cause confusion if the next pass got the wrong value. This patch makes sure that, if metadata already exists in a loop, the hint mechanism will never append a new node, but always replace the existing one. It also enhances the algorithm to cope with more metadata types in the future by just adding a new type, not a lot of code. Re-applying again due to MSVC 2013 being minimum requirement, and this patch having C++11 that MSVC 2012 didn't support. Fixes PR20655. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216870 91177308-0d34-0410-b5e6-96231b3b80d8		2014-09-01 10:00:17 +00:00

Analysis	Remove an errant outer loop that contains nothing but an inner loop over exactly the same elements. While no functionality is change intended (and hence there are no changes to tests), you don't want to skip this revision if bisecting for errors.	2014-09-01 05:17:15 +00:00
