[llvm-commits] [llvm] r96426 - in /llvm/trunk/include/llvm/CodeGen: DAGISelHeader.h SelectionDAGISel.h

New Revision: 96426

URL: http://llvm.org/viewvc/llvm-project?rev=96426&view=rev
Log:
make the new isel's interpreter loop call the generated 
CheckComplexPattern function.  Though it is logically const,
I don't have the fortitude to clean up all the targets now,
and it not being const doesn't block anything.
