in case of 1, the function is marked as arm, and the thumb code begins with a label of the form '.real_start_of<funcname>'. in case of 2, the function is marked as thumb, and arm code begins with a label of the form '__<arm_function_to_be_called>_change_to_arm'.

both the labels have type STT_NOTYPE in symtab. so is it the label name that is being used to distinguish between arm/thumb? if yes, is there any other label name that is used for this purpose?

a label for a thumb code has different type than that for an arm code. above observation is wrong. sorry for the slip. thanks Richard for your help.
