Hi, I have a problem with the following scenario: I use the ProfileEstimatorPass to get ProfileInfo and verifiy this info with the ProfileVerifierPass. (Please bear with me, its not about the profiling but about the Pass interaction.) Then the LowerSetJumpPass is executed and I want to verify that the esimtated ProfileInfo survives this pass by calling again the ProfileVerifierPass. This is what it looks like: No Profile Information ModulePas...

This caused OPT to give a warning "WARNING: profile information is inconsistent with the current program!" and then fail with an assert (ASSERT:inWeight and outWeight do not match opt: ProfileVerifierPass.cpp:226: void<unnamed>::ProfileVerifierPassT<FType, BType>::CheckValue(bool, const char*, <unnamed>::ProfileVerifierPassT<FType, BType>::DetailedBlockInfo*) [with FType = llvm::Function, BType = llvm::BasicBlock]: Assertion `0 && (Message)' failed.)
