[cfe-dev] Printing changes after "emit" in Clang CodeGen

[Arnamoy Bhattacharyya via cfe-dev]

Hello;

I am trying to identify the changes introduced by different functions
in CodeGenFunction of Clang. For example, if I want to see what was
"emitted" by printing before and after a call to
emitOMPSimdRegion(CodeGenFunction &CGF, OMPLoopDirective &S,
PrePostActionTy){}, I was trying S.dump().  It did not show any
changes.  Is there any
printing utility we can use to print changes introduced by different emissions?

Thank you
