The original implementation of the trait is unable to correctly retrieve the arguments of a function, necessitating a rewrite. This includes two interfaces:
from_argument
andfrom_retval
.To access a function's argument, it is necessary to accurately identify the register address where the argument is stored. Subsequently, we can use the function to read
the contents at this register address.
This allows us to correctly retrieve the argument of the function.
