Also can use "objdump -D prog.elf" and see what addresses are occupied by
the non-debug/non-info sections. Usually, the sections starting at
<.comment> and on are non-loadable sections. You could identify them by the
"*unknown*" opcodes and by their 00000000 starting address. Use "objdump -D
prog.elf | grep '>:'" to get a list of the sections and their addresses.
