2012-02-10Update BBVectorize to use aliasesUnknownInst.Hal Finkel
This allows BBVectorize to check the "unknown instruction" list in the alias sets. This is important to prevent instruction fusing from reordering function calls. Resolves PR11920. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150250 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-04Boost the effective chain depth of loads and stores.Hal Finkel
By default, boost the chain depth contribution of loads and stores. This will allow a load/store pair to vectorize even when it would not otherwise be long enough to satisfy the chain depth requirement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149761 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-02BBVectorize: Simplify code, no functionality change.Benjamin Kramer
Also silences warnings about bodyless for loops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149612 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-02Minor changes from review.Hal Finkel
As suggested by Nick Lewycky, the tree traversal queues have been changed to SmallVectors and the associated loops have been rotated. Also, an 80-col violation was fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149607 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-02Vectorize long blocks in groups.Hal Finkel
Long basic blocks with many candidate pairs (such as in the SHA implementation in Perl 5.14; thanks to Roman Divacky for the example) used to take an unacceptably-long time to compile. Instead, break long blocks into groups so that no group has too many candidate pairs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149595 91177308-0d34-0410-b5e6-96231b3b80d8

are incompatible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149475 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-01A few of the changes suggested in code review (by Nick Lewycky)Hal Finkel

2012-02-01Add a basic-block autovectorization pass.Hal Finkel
This is the initial checkin of the basic-block autovectorization pass along with some supporting vectorization infrastructure. Special thanks to everyone who helped review this code over the last several months (especially Tobias Grosser). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149468 91177308-0d34-0410-b5e6-96231b3b80d8
