Target piece, if there is one. PR44183 for the vectorizer piece, if there is

I'm almost certain

valgrind sucks (maybe report this to them).

For starters it would be nice if gfortran would even document its precise
semantics for when module files

I think it would be useful to give an example Makefile file in the manual.

BTW, there is one thing I would still like to add, but I have not yet tried.
gfortran -fsyntax-only test.f90
will generate all .mod files

I actually vaguely recall why this should be a warning, and not be checked for
at runtime. This is for legacy codes using real :: a(1

Not sure if that solves the issue, but CP2K uses these rules:
%.o: %.F
$(FC) -c $(FCFLAGS) $
%.mod: %.o

-march=native is ambiguous, please see with -v what actually is being used.

actually, I think this is a kind of error that should be caught at run-time
