description:

In this script, we iterate through a function
|
|
arguments and display information about their
|
|
location and size. For this we:
|
|
* get the function type information
|
|
* iterate through the arguments
|
|
* for each of them we print its location (register or stack),
|
|
offset (if in stack) and size
