Dhrystone is (and probably always was) a bogus benchmark. It's a well-known truism that MIPS stands for Meaningless Indication of Processor Speed, and dhrystone scores are equally meaningless. Dhrystone fell out of common usage over 20 years ago.

It's not GCC that is being peculiar, it's just Dhrystone is pointless.

That's true, I did notice GCC being rather ... peculiar about
drhystone. Is there a way to make it less clever about the benchmark?

Or is there some alteration to the benchmark I can make to not trigger
the special behavior in GCC?

Trying to use the dhrystone isn't going to be very useful. It has
many downsides not the least is that gcc's optimizer can run rings
about it.
