            Bug ID: 45471
           Summary: SymbolFileDWARF::ParseVariableDIE consider all
                    constant variables as "static"
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at lists.llvm.org
          Reporter: ditaliano at apple.com

SymbolFileDWARF::ParseVariableDIE has the following code:

          if (location_is_const_value_data)
            scope = eValueTypeVariableStatic;
          else {
            scope = eValueTypeVariableLocal;

So every variable that just has a constant value, and isn’t in a location, is
treated as a file static.  That means, for instance, if you build this:

volatile int a; 
   main() {
          {
            int b = 3;
            a;
          }
        }


Break on line 5 and run to it, you get:

(lldb) frame var 
(lldb)

It is a local variable, however, so we should print it.
