Do we need here as well? https://github.com/intel/llvm/blob/sycl/sycl/test-e2e/Basic/built-ins/marray_math.cpp

for now, we have seen failures due to fast-math enabled on some specific tests. I would suggest to adapt tests one by one if we really see the difference in this option being enabled and disabled.

Sounds good to me. Just FYI, these math build-in overloads with support of marray call scalar math built-ins inside them. The test for scalar math built-ins was modified in this PR.

thanks for highlighting it! I will double check to confirm if marray test could fail as well.
