[llvm-commits] [llvm] r83282 - /llvm/trunk/lib/Transforms/Utils/SSI.cpp

Author: resistor
Date: Sun Oct  4 12:47:39 2009
New Revision: 83282

URL: http://llvm.org/viewvc/llvm-project?rev=83282&view=rev
Log:
SSI needs to require DT and DF transitively, since it uses them outside of its runOnFunction.
Similarly, it can be marked setPreservesAll, since it does no work in its runOnFunction.
