Matthijs Kooijman d16918f843 Restructure dead argument elimination, try #3 :-) ... Rewrite the DeadArgumentElimination pass, to use a more explicit tracking of dependencies between return values and/or arguments. Also make the handling of arguments and return values the same. The pass now looks properly inside returned structs, but only at the first level (ie, not inside nested structs). This version fixed a few more bugs and was cleaned up a bit. It now passes all of LLVM's testing, and should still pass SPEC2006. There is still a minor bug with regard to returning nested structs. Since there is currently nothing that emits such IR, I will fix that in a seperate commit (partly because it requires a non-trivial fix). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53400 91177308-0d34-0410-b5e6-96231b3b80d8		2008-07-10 10:24:08 +00:00
