Dan Gohman 4d70a29490 Factor out Instruction::isSafeToSpeculativelyExecute's code for ... testing for dereferenceable pointers into a helper function, isDereferenceablePointer. Teach it how to reason about GEPs with simple non-zero indices. Also eliminate ArgumentPromtion's IsAlwaysValidPointer, which didn't check for weak externals or out of range gep indices. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118840 91177308-0d34-0410-b5e6-96231b3b80d8		2010-11-11 21:23:25 +00:00
