OpenCL spec (https://www.khronos.org/registry/OpenCL/sdk/1.2/docs/man/xhtml/clBuildProgram.html) says that "cl-unsafe-math-optimizations" option allows a lot of optimizations and generated source code of Add<N> tests can be completely optimized out. E.g. s0=10.f-s0; s0=10.f-s0; can be optimized to s0=s0; when -cl-unsafe-math-optimizations is specified. At least clang compiler started to eliminate this code a time ago. It seems for this trivial test the option should be removed in order to avoid such optimizations.
