The lines I wrote is a simple main() func without any floating point.
Just initialise two integer, add two and exit. When I used the hexedit
utility to view the executable its showing a huge space filled with 00
. What possibly is the reason??

when I used $arm-elf-gcc -o test -save-temps test.c

I am getting proper intermediate file and when I used the arm-elf-as
against test.s the same thing happened.
