We all know that there are two kinds of instruction, arm and thumb. Here is the question: how can I get the right instruction type of the functions from elf file which contains mixed thumb and arm intruction?

    What do you mean by 'right' in this context? They are both perfectly right :D
    You can make an asm listing from elf and you'll easily distinguish ARM from Thumb by instructions' lengths.
    (I'm not yet closely familiar with Thumb2, so I'm not commenting on this).
