[Bug debug/35463] New: typedef missing in debug information with -gdwarf-2 for c++

[Bug debug/35463] New: typedef missing in debug information with -gdwarf-2 for c++

[mrs at apple dot com]

typedef struct {
  int x;
} mystruct;
mystruct m;

is missing any debug information for mystruct.  If one compiles as C, mystruct
is present.

Still broken in 20080308 compiler.  Should be target independent.

I verified this to be the case since 4.1.0.  The last version this was working
was 4.0.4. 

Also this is specific to anonymous struct.  If the struct is named, it works
fine.  

This is sever issue for us when we moved from RHEL4 (gcc 3.4.6) to RHEL5 (gcc
4.1.2) that most of our gdb scripts stopped working which were heavily relying
on using typedef names of anonymous structs.

Just that I agree this Bug looks to me fixed in g++-4.5.

The sample code like what is Comment 0 here from:
http://gcc.gnu.org/ml/gcc-help/2009-04/msg00393.html

gives DW_TAG_structure_type DW_AT_name "<anonymous struct>" on:
g++ (GCC) 4.4.0 20090427 (Red Hat 4.4.0-3)

and gives DW_TAG_structure_type DW_AT_name "type27" on:
g++ (GCC) 4.5.0 20090430 (experimental)
