Support for no-LLVM compilers?

We have been using PGI compilers for our CUDA Fortran application, and recently moved to HPC SDK.
Looks like the Fortran compilers being shipped with the HPC SDK are LLVM-based.
However, we are observing slowdowns in our applications compared to when we were using no-LLVM versions in the PGI compiler suite.
Is there a legacy no-LLVM compilers support?
