I have tried to use avr-gcc to produce dwarf debug information with the -gdwarf, -gdwarf-1 and -gdwarf-2 flags,
but it seems this is not supported:

// compiler output:
avr-gcc -c -gdwarf -Os -Wall -Wstrict-prototypes -Wa,-ahlms=gcctest1.lst -mmcu=
   at90s8515 -I. gcctest1.c -o gcctest1.o
   cc1.exe: warning: `dwarf': unknown or unsupported -g option
avr-gcc gcctest1.o -Wl,-Map=gcctest1.map,--cref -mmcu=at90s8515 -o gcctest1.elf

My avr-gcc version is:
gcc version 3.2 20020616 (experimental).

objdump inspections of the produced object files show that stabs debug information is produced instead.

Is there currently an avr-gcc that produces dwarf debug information?
Or are there any plans to support dwarf in future releases?
