[LLVMdev] Limitations of Alias Analysis?

[Wenzhi Tao]

Hi Eli,
  I'm using trunk LLVM:

SVN-URL: http://llvm.org/svn/llvm-project/llvm/trunk
Version: 74580

  The result of llvm-config --version is '2.6svn'.

  And, when I try the released version 2.5, it still reports that %0 and
%1 are MayAlias. I wonder why I can't get the same result with you.
Thank you.
