Oh, also this one lowers the Ada execution time by around 10%: do not
use an unconstrained type and do not use pointers.
N : constant Positive := Positive'Value (Argument (1));
G : Ada.Numerics.Float_Random.Generator;
type Real_Matrix is array(1 .. N, 1 .. N) of Float;
pragma Convention (Fortran, Real_Matrix);
A,B,C : Real_Matrix;
And as Duncan says, you should try with a newer backend for Ada.
Sam
