Now PassManager is just a Pimpl class that wraps PassManagerT<Module>, but lib/VMCore/Pass.cpp is now the only class that has to #include PassManagerT.h git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2383 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | - Rename runOnMethod to runOnFunction * Transform getAnalysisUsageInfo into getAnalysisUsage - Method is now const - It now takes one AnalysisUsage object to fill in instead of 3 vectors to fill in - Pass's now specify which other passes they _preserve_ not which ones they modify (be conservative!) - A pass can specify that it preserves all analyses (because it never modifies the underlying program) * s/Method/Function/g in other random places as well git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2333 91177308-0d34-0410-b5e6-96231b3b80d8
