* Remove the CFGElement "Invalid" state.David Blaikie2013-02-231-4/+4
| | | | | | | | | | | | | Use Optional<CFG*> where invalid states were needed previously. In the one case where that's not possible (beginAutomaticObjDtorsInsert) just use a dummy CFGAutomaticObjDtor. Thanks for the help from Jordan Rose & discussion/feedback from Ted Kremenek and Doug Gregor. Post commit code review feedback on r175796 by Ted Kremenek. llvm-svn: 175938

* Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth2012-12-041-5/+5

I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237

| | | | | | | | | | | | be linearized only when used by the static analyzer. This required a rewrite of LiveVariables, and exposed a ton of subtle bugs. The motivation of this large change is to drastically simplify the logic in ExprEngine going forward. Some fallout is that the output of some BugReporterVisitors is not as accurate as before; those will need to be fixed over time. There is also some possible performance regression as RemoveDeadBindings will be called frequently; this can also be improved over time. llvm-svn: 136419
