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;
};
----------------------------------

-feliminate-dwarf2-dups has been disabled for C++ (see PR46102). However, as
noted by Ian in the thread in #c1, there are better ways of removing duplicates
in dwarf4. Consequently, I don't believe this should be in the "serious
regression" category. Downgrading.

FWIW I don't know if I agree that .debug_types is "better"; there's currently
no way to refer to children of the type, so we end up creating "skeleton" DIEs
in the main CU anyway.
