Dan Gohman a8225083ba Make LSR's OptimizeShadowIV ignore induction variables with negative ... strides for now, because it doesn't handle them correctly. This fixes a miscompile of SingleSource/Benchmarks/Misc-C++/ray. This problem was usually hidden because indvars transforms such induction variables into negations of canonical induction variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85118 91177308-0d34-0410-b5e6-96231b3b80d8		2009-10-26 15:32:57 +00:00
