Evan Cheng ed1c0c7f58 Revert r145273 and fix in SelectionDAG::InferPtrAlignment() instead. ... Conservatively returns zero when the GV does not specify an alignment nor is it initialized. Previously it returns ABI alignment for type of the GV. However, if the type is a "packed" type, then the under-specified alignments is attached to the load / store instructions. In that case, the alignment of the type cannot be trusted. rdar://10464621 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145300 91177308-0d34-0410-b5e6-96231b3b80d8		2011-11-28 22:37:34 +00:00
