I'm not sure what the appropriate solution is, but the test now does not
work with Intel anymore.
On the machine the originally motivated my modification of the AVX test,
the test used to appropriately fail with the message:
Fatal Error: This program was not built to run on the processor in your
The allowed processors are: Intel(R) processors with Intel(R) AVX
After your change, the test passes, and yet Octopus dies with the error
forrtl: severe (168): Program Exception - illegal instruction
when built this way. I think that, for ifort at least, without -avx it does
not actually generate code using AVX instructions, and so we will only be
checking that the compiler knows how to generate them but not whether the
hardware supports them. Are you sure that the test with gcc is really
checking the hardware either?
