Dale Johannesen dd1f9e4bf6 Enhance induction variable code to remove the ... sext around sext(shorter IV + constant), using a longer IV instead, when it can figure out the add can't overflow. This comes up a lot in subscripting; mainly affects 64 bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69123 91177308-0d34-0410-b5e6-96231b3b80d8		2009-04-15 01:10:12 +00:00
