llvm/test/Transforms/BBVectorize, branch release_31http://llvm.orghttps://git.amat.us/llvm/atom/test/Transforms/BBVectorize?h=release_312012-04-14T07:32:50ZFix an error in BBVectorize important for vectorizing pointer types.2012-04-14T07:32:50ZHal Finkelhfinkel@anl.gov2012-04-14T07:32:50Zurn:sha1:bba23ed672c4cedd61a302497f45bf6f53fec7b2
When vectorizing pointer types it is important to realize that potential
pairs cannot be connected via the address pointer argument of a load or store.
This is because even after vectorization, the address is still a scalar because
the address of the higher half of the pair is implicit from the address of the
lower half (it need not be, and should not be, explicitly computed).

Correctly vectorize powi.2012-03-31T03:38:40ZHal Finkelhfinkel@anl.gov2012-03-31T03:38:40Zurn:sha1:6173ed95daf2f209fe3883faee45967e4800ae75
The powi intrinsic requires special handling because it always takes a single
integer power regardless of the result type. As a result, we can vectorize
only if the powers are equal. Fixes PR12364.

Replace all instances of dg.exp file with lit.local.cfg, since all tests are run with LIT now and now Dejagnu. dg.exp is no longer needed.2012-02-16T06:28:33ZEli Benderskyeli.bendersky@intel.com2012-02-16T06:28:33Zurn:sha1:0f0c411079cd21bb3a81a1b70bf8c67539a16c22
Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches.

Update BBVectorize to use aliasesUnknownInst.2012-02-10T15:52:40ZHal Finkelhfinkel@anl.gov2012-02-10T15:52:40Zurn:sha1:38a7f22445b8782682d1f8f253454ea0390d4ac5
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.

Boost the effective chain depth of loads and stores.2012-02-04T04:14:04ZHal Finkelhfinkel@anl.gov2012-02-04T04:14:04Zurn:sha1:edc8db87dc2ed4d2971e7f50464f5f4d0fead537
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.

Add a basic-block autovectorization pass.2012-02-01T03:51:43ZHal Finkelhfinkel@anl.gov2012-02-01T03:51:43Zurn:sha1:de5e5ec3045a73a06b1054417f9ac6c02929e9ce
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).
