Hi, How can I use profile information into my pass for performing some analysis. I tried something like: PassManager PassMgr = PassManager(); cl::opt<std::string> ProfileDataFile(cl::Positional, cl::desc("<llvmprof.out file>"), cl::Optional, cl::init("llvmprof.out")); PassMgr.add(createProfileLoaderPass(ProfileDataFile)); PassMgr.run(M); ProfileInfo *PI; PI = &getAnalysis<ProfileInfo>(); But thi...

...for typeinfo MyAna() : ModulePass(&ID) {} virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesAll(); AU.addRequired<ProfileInfo>(); } bool runOnModule(Module &M) { PassManager PassMgr = PassManager(); cl::opt<std::string> ProfileDataFile(cl::Positional, cl::desc("<llvmprof.out file>"), cl::Optional, cl::init("llvmprof.out")); PassMgr.add(createProfileLoaderPass(ProfileDataFile)); PI = &getAnalysis<ProfileInfo>(); } }; } char MyAna::ID = 0; static Register...

Here is the bulk of the sanitizing. My residual doubts center around the question whether we still do/want to support (un)compressed *byte*code in 2.0/2.1. I need a definitive word on this to proceed. My understanding is that bytecode is already gone, but there are still some functions/enums that really deal with *byte*code (instead of *bit*code). I did not touch those areas, so the attached
