elf2hex switches

[coolblue]

Hi all,
 I have a series of questions:
1. Are elf2hex utilities same for all processors? are there different
elf2hex converters for different processors?
2. I use ARC processor which uses hcac command for compilation. then i
use elf2hex to convert elf top hex. the switches used in the script
are "elf2hex -ctldb -m test.out". what does ctldb mean? and what does
m refer to?
3. what does "elfdump -z test.out" command do?

Thank you,
Kaushik
