Is my -f(no-)directives patch okay? Or do you envision something else?
In principle, it is OK; the only question is what the default should
be :-)
I am in favor of "on".
For OpenMP, we require an option to change the semantics of a program
based on special comments. Currently, we do not do so for directives
which do the same thing.
Well, I see a difference here: (Nearly) all program using OpenMP work
also as serial program (-fno-openmp). On the other hand, without "!GCC$
attributes" directives (or the C equivalent: "__attribute__((...))"),
the program does not work properly. The attributes are used to be able
to express some feature which is not available in the standard but still
in some way required: stdcall, fastcall, dllimport, dllexport. "unused"
arguments, weak bindings (not yet for Fortran), disabling argument
checking (only Fortran), etc.
