* Add VectorTargetTransform::getNumberOfParts.Hal Finkel2012-10-261-0/+8
| | | | | | | As discussed on IRC, add VectorTargetTransform::getNumberOfParts to provide a stable interface to the vector legalization splitting factor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166751 91177308-0d34-0410-b5e6-96231b3b80d8

* Temporarily revert the TargetTransform changes.Bob Wilson2012-10-181-43/+0
| | | | | | | | | | | The TargetTransform changes are breaking LTO bootstraps of clang. I am working with Nadav to figure out the problem, but I am reverting it for now to get our buildbots working. This reverts svn commits: 165665 165669 165670 165786 165787 165997 and I have also reverted clang svn 165741 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166168 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a new interface to allow IR-level passes to access codegen-specific ↵Nadav Rotem2012-10-101-0/+43
