2009-05-07Revert r70876 and add a testcase (@c7) showing the problem:Duncan Sands
bits captured, but the pointer marked nocapture. In fact I now recall that this problem is why only readnone functions returning void were considered before! However keep a small fix that was also in r70876: a readnone function returning void can result in bits being captured if it unwinds, so test for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71168 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-18BasicAliasAnalysis and FunctionAttrs were bothDuncan Sands
doing very similar pointer capture analysis. Factor out the common logic. The new version is from FunctionAttrs since it does a better job than the version in BasicAliasAnalysis git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62461 91177308-0d34-0410-b5e6-96231b3b80d8
