Chris Lattner 6807ddd3d9 * Sink 4 duplicates of edge threading validity checks and DOUT prints into ... ThreadEdge directly. This shares the code, but is just a refactoring. * Make JumpThreading compute the set of loop headers and avoid threading across them. This prevents jump threading from forming irreducible loops (goodness) but also prevents it from threading in other cases that are beneficial (see the comment above FindFunctionBackedges). llvm-svn: 70820		2009-05-04 02:28:08 +00:00
