missing .debug_frame section in objectfiles from avr-gcc 3.4.0

[Torleif Sandnes]

Hi.

I configured and built the most recent gcc snapshot:

$ avr-gcc -v
Reading specs from /usr/local/lib/gcc/avr/3.4.0/specs
Configured with: ./configure --prefix=/usr/local --enable-languages=c,c++ 
--target=avr --with-dwarf2
Thread model: single
gcc version 3.4.0 20040324 (prerelease)

This seems ok, but I cannot get avr-gcc to output .debug_frame sections.

I did take a look at this document
http://www.sunsite.ualberta.ca/Documentation/Gnu/gcc-3.0.2/html_node/gcc_295.html#SEC295 

and tried adding
#define DWARF2_FRAME_INFO   1
to gcc/configure/avr/avr.h and rebuilt gcc, but this did not help.

Does anybody know how to make avr-gcc emit the dwarf debug frame information?
Is there a configure flag or something that governs this, or do I have to edit 
the machine description files?

regards,
