AVR-GCC compiler options

[Ruchi Varshney]

Hi,I am looking for a way to intermix source code with the asm code
generated when I compile a .c file "avr-gcc -S" option.
Right now, I know that when I use "avr-objdump -S" on the .s file obtained
from avr-gcc, I can see that the output is intermixes with the actual source
code from the .c file. Is there a way I can get the source code to appear in
the .s file when I use "avr-gcc"?

Thanks
