Hello Gabriele,

Does setting the environment variable NO_STOP_MESSAGE help?
export NO_STOP_MESSAGE=1

Subject: [flang-dev] arm + denormals


Hello,

I am running into the problem that flang checks to see if they are denormals. If it thinks they are denormals, it prints out a warning. That slows down the runtime a lot.

Other folks have compiled the same code with ifort using -ftz, probably because they are not concerned about underflows. Is there something similar available for flang, to avoid the checking/printing warnings?

Thanks and greetings,





Gabriele Jost
