Explore the details of subroutine calls in the GNU Ada translator gnat. Pay

particular attention to the more complex language features, including declarations in nested blocks (Section 3.3.2), dynamic-size arrays (Section 8.2.2),

in/out parameters (Section 9.3.1), optional and named parameters (Section 9.3.3), generic subroutines (Section 7.3.1), exceptions (Section 9.4),

and concurrency (“Launch-at-Elaboration,” Section 13.2.3).
