List of macros option for nvfortran like for nvc?

Accelerated Computing HPC Compilers nvc, nvc++ and nvfortran
1

Like for GCC, you can use -dM with nvc to dump predefined macros. Is there a similar option for Fortran? (If not, as seems the case, will there be?)

It’s the same, though you do need to have preprocessing enabled, either via the flag “-Mpreprocess”, or by default when using capitols in the suffix like “.F90”.

Thanks, Mat! Embarrassing I didn’t make the preprocessor connection :)

Is there a way to #ifdef that it’s nvfortran? (Other than using the old PGI macros and presumably this will change in the not distant future)

I’d use “__NVCOMPILER”.

OK, thanks. That’s what I was doing in the interim, anyway
