Nadav Rotem 25961b469a SLP Vectorizer: Add support for vectorizing parts of the tree. Untill now we detected the vectorizable tree and evaluated the cost of the entire tree. With this patch we can decide to trim-out branches of the tree that are not profitable to vectorizer. Also, increase the max depth from 6 to 12. In the worse possible case where all of the code is made of diamond-shaped graph this can bring the cost to 2**10, but diamonds are not very common. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184681 91177308-0d34-0410-b5e6-96231b3b80d8	2013-06-24 02:52:43 +00:00

Nadav Rotem 25961b469a SLP Vectorizer: Add support for vectorizing parts of the tree.

Untill now we detected the vectorizable tree and evaluated the cost of the
entire tree.  With this patch we can decide to trim-out branches of the tree
that are not profitable to vectorizer.

Also, increase the max depth from 6 to 12. In the worse possible case where all
of the code is made of diamond-shaped graph this can bring the cost to 2**10,
but diamonds are not very common.
