Dan Gohman f241174421 Revert the addition of hasNoPointerOverflow to GEPOperator. ... Getelementptrs that are defined to wrap are virtually useless to optimization, and getelementptrs that are undefined on any kind of overflow are too restrictive -- it's difficult to ensure that all intermediate addresses are within bounds. I'm going to take a different approach. Remove a few optimizations that depended on this flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76437 91177308-0d34-0410-b5e6-96231b3b80d8		2009-07-20 17:43:30 +00:00
