Chris Lattner 7c95debb49 Fix a bug compiling PR1978 (perhaps not the only one though) which ... was incorrectly simplifying "x == (gep x, 1, i)" into false, even though i could be negative. As it turns out, all the code to handle this already existed, we just need to disable the incorrect optimization case and let the general case handle it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46739 91177308-0d34-0410-b5e6-96231b3b80d8		2008-02-05 04:45:32 +00:00
