Suppose you have such a machine (wow! talk about complex instruction sets!).
I then grant that any good Fortran compiler would use it. However, it also
follows that any Ada compiler could create a small function to use it (e.g.
using Machine code insertions), and then pragma Inline that function.

What about compiling for a CPU, that does have an instruction for
matrix multiplication? It seems absurd to me, not to use that
instruction, if it is available.
