[llvm-dev] Scope differentiate.

[Umesh Kalappa via llvm-dev]

Hi All ,

We added the below code to differentiate Local  and Global Variable in
the "NamedDecl *Sema::HandleDeclarator" function.

if(S->getFlags() == Scope::DeclScope)
 its global
else
 its local

Where S  is a pointer parameter to the  HandleDeclarator of type Scope.

At first place ,we decided  to use
"D.getDeclSpec().getStorageClassSpec()" ,but has no luck ,since its
always "SCS_unspecified " .

Question is that , do using the  "Scope::DeclScope" to differentiate
the variable scope is the  right approach, if so

we have a problem for some instance like a nested  local declaration,
we are not able to differentiate.

if the "Scope::DeclScope" is not the right approach, then  please
anybody here , help us with the right approach and would like to
inform you all that, we need this info before any Act call like
"ActOnVariableDeclarator"

Thank you
