[cfe-dev] How to identify the end of a branch in the symbolic execution in clang?

[Pengfei Wang via cfe-dev]

I am writing a taint tracking checker with clang static analyzer,  and
currently I want to do something when a branch is finished being analyzed.
So I need to know when the symbolic execution reaches the end of a branch,
which means how can I notice that the symbolic execution reaches the end of
an If code block or Else code block? I have tried the CompoundStmt, but it
didn't work in the callback function CheckPostStmt<CompoundStmt>, and
neither did the BlockExpr work. Are there any possible ways to achieve this
goal?

Thank you!
