There are pragmata suppress (standard) and it
is meaningful to apply them. What I do for
number-crunching with big matrices is
to compile the whole with two different option sets

1/ a "debug" without suppressing anything, no optimization
   and eventual compiler-dependent extra checks

2/ a "compute" one with suppress_all, plus all optimization
   goodies provided by the compiler, including loop-unrolling

You can always add a few before-calculation explicit
checks to verify data consistency, e.g.
