* Address warnings on NVIDIA nvc++ Types of warnings were being generated: 1. Deprecated warnings - solved by defining the relevant BENCHMARK_* macros for nvc++ and adding pragma suppress on a couple of .cc files 2. Setup/TearDown const vs non-const partial override - solved by adding non-const version 3. Static but not referenced - added diagnostic suppress for that file * Modified manually to comply with CD/CI * Revert partial override * Suppress warnings from tests if compiler is NVHPC --------- Co-authored-by: dominic <510002+dmah42@users.noreply.github.com>
