             Bug #: 53118
           Summary: [4.5/4.6/4.7 regression] -feliminate-dwarf2-dups is
                    broken for C++
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: wrong-debug
          Severity: normal
          Priority: P3
         Component: debug
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jason@gcc.gnu.org


As noted in http://gcc.gnu.org/ml/gcc-help/2010-09/msg00081.html ,
-feliminate-dwarf2-dups has been broken for C++ ever since GCC 4.0; the front
end now tokenizes the entire input before doing any parsing, so the calls to
dwarf2out_{start,end}_source_file are all clustered at the beginning rather
than properly wrapping the contents of headers.

Testcase from that message:

------ source file bar.c: --------
#include "foo.h"
#include "bar.h"

struct Foo myfoo;
struct Bar mybar;
----------------------------------

------ header file foo.h: --------
struct Foo {
    double d_foo;
    int i_foo;
};
----------------------------------

------ header file bar.h: --------
struct Bar {
    double d_bar;
    int i_bar;
    char c_bar;
};
----------------------------------
