I've been experimenting with -gdwarf-2 -feliminate-dwarf2-dups in libstdc++.
This combination of flags reduces the shared binary by 400k.
-g -O2
-rwxrwxr-x 1 bkoz bkoz 4.0M libstdc++.so.5.0.2*
-gdwarf-2 -feliminate-dwarf2-dups -O2
-rwxrwxr-x 1 bkoz bkoz 3.6M libstdc++.so.5.0.2*
The build and testsuite complete without incident, but then when I try to
debug, I get:
(gdb) file a.out
Reading symbols from a.out...DW_FORM_strp pointing outside of .debug_str section
This is with mainline gdb, and the dcarlton branch, with top-of-tree
gcc, on x86/linux.
Any ideas?

I think we are not doing this yet. There was some initial work done by
Jim Blandy, but I am not sure where that is at right now.

Thanks. Can somebody in gdb land make a note of this request, and let me
know when things are working?
Thanks,

Actually, could you file a gnats PR, and put it in the symtab/debug
info category?
We'll keep you posted.
