[llvm-commits] [llvm] r77025 - in /llvm/trunk: include/llvm/ADT/SparseBitVector.h unittests/ADT/SparseBitVectorTest.cpp

New Revision: 77025

URL: http://llvm.org/viewvc/llvm-project?rev=77025&view=rev
Log:
Add a missing ilist_node.h #include to SparseBitVector, and add a very short
test for it. The test is by no means complete, but it tests the problem I was
fixing.

Added:
    llvm/trunk/unittests/ADT/SparseBitVectorTest.cpp
Modified:
