Chris Lattner d7f5a58890 Truncate GEP indexes larger than the pointer size down to pointer size ... when doing this transform if the GEP is not inbounds. No testcase because it is very difficult to trigger this: instcombine already canonicalizes GEP indices to pointer size, so it relies specific permutations of the instcombine worklist. Thanks to Duncan for pointing this possible problem out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92495 91177308-0d34-0410-b5e6-96231b3b80d8		2010-01-04 18:57:15 +00:00
