            Bug ID: 21182
           Summary: link time optimization fails for huffman loop
           Product: clang
           Version: unspecified
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

When I compile the following code using clang with -flto it fails by printing
900. Without the -flto option it correctly prints 801.

I checked out the LLVM code (using clang -flto -S simple.c) nothing seems
incorrect to me. And compiling using clang 3.5 llc gives indeed the correct
value. But compiling using clang 3.5 opt gives me again the incorrect value.
