I noticed today that fp-model no longer has an entry in the Intel 19.1.2 (2020.2.254) ifort man page. It seems to still work as my code which uses fp-model flags still builds, but the fact that it's now not in the man page makes me ask: is fp-model deprecated?
If so, what should I be transitioning my code to use instead of fp-model?
Last I knew (3-4 years ago), the man page was automatically generated and should be complete. I might expect some obsolete options to be omitted, but -fp-model is a "first class" option. I don't have a Linux license to test, but the equivalent Windows option shows with ifort /?.
I suggest you post a query in the Intel Online Service Center about it.
