Eli Friedman b80f778bd3 Get rid of an optimization in SCCP which appears to have many issues. Specifically, it doesn't handle many cases involving undef correctly, and it is missing other checks which ... lead to it trying to re-mark a value marked as a constant with a different value. It also appears to trigger very rarely. Fixes PR11357. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144352 91177308-0d34-0410-b5e6-96231b3b80d8		2011-11-11 01:16:15 +00:00

GlobalOpt	Refactor code from inlining and globalopt that checks whether a function definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead. This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress. (GlobalDCE can also handle the given tescase, but we only run that at -O3.)
