New Revision: 54725

URL: http://llvm.org/viewvc/llvm-project?rev=54725&view=rev
Log:
Rename this, in case people think that NullFolder
has something to do with folding null values.

Added:
    llvm/trunk/include/llvm/Support/NoFolder.h   (contents, props changed)
      - copied, changed from r54698, llvm/trunk/include/llvm/Support/NullFolder.h
Removed:
    llvm/trunk/include/llvm/Support/NullFolder.h

Copied: llvm/trunk/include/llvm/Support/NoFolder.h (from r54698, llvm/trunk/include/llvm/Support/NullFolder.h)
URL: http://llvm.org/viewvc/llvm-project/llvm/trunk/include/llvm/Support/NoFolder.h?p2=llvm/trunk/include/llvm/Support/NoFolder.h&p1=llvm/trunk/include/llvm/Support/NullFolder.h&r1=54698&r2=54725&rev=54725&view=diff
