Hello.
I have a question. I posted it first on stackoverflow.
https://stackoverflow.com/questions/77585795/how-do-i-get-gfortran-to-generate-architecture-specific-predefined-macros.
The question is how do I get gfortran to generate architecture specific predefined macros like __SSE2__, __AVX__ and __AVX512F__?
If I run
echo | gfortran -E -dM -march=native
I get the desired predefined macros printed to the screen. If I compile with
gfortran -c <source.f90> -cpp -march=native
I don't get all of the predefined macros. It is almost as if gfortran does not pass the compiler option -march=native to the preprocessor.
Best,
Rasmus Vikhamar
