[cfe-dev] How to get global variables' SymbolRef?

[edward jiamu]

Thank you for your advice very much.

At last the problem is solved by this way:
1) record the "VarDecl* p" of global variable in the checkASTDecl
2) get the SymbolRef by recorded "VarDecl* p" in the evalCall
  SVal sv = state->getLValue(p, C.getLocationContext());
  const SymbolRef symRef = sv.getAsSymbol();

Do this to get the unique id of global variables and local variables.
