Nick Lewycky 6977e79526 Support pointer comparisons against constants, when looking at the inline-cost ... savings from a pointer argument becoming an alloca. Sometimes callees will even compare a pointer to null and then branch to an otherwise unreachable block! Detect these cases and compute the number of saved instructions, instead of bailing out and reporting no savings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148941 91177308-0d34-0410-b5e6-96231b3b80d8		2012-01-25 08:27:40 +00:00
