NVHPC won't generate the optimal memory layout for proxy when no dispatch is specified, causing static assertions to fail. Although this is a QoI issue for the compiler, we have worked around this by specifying a different base type for proxy in this case.
NVHPC treats inline const variable as constexpr, causing static_assert(!pro::facade<BadFacade_BadConstraints_NotConstant>) to fail. This should be a bug in NVHPC. I simply worked around the issue in this change by splitting the definition of the variable from its declaration.
NVHPC creates an additional copy for the value when using static_cast, causing ProxyLifetimeTests.Test_DirectConvension_Lvalue and ProxyLifetimeTests.Test_DirectConvension_Rvalue to fail. This is a bug in the existing unit test implementation since copy elision is not guaranteed for static_cast.
Modified tests/CMakeLists.txt to exclude freestanding test cases from unsupported compilers like NVHPC.
Suppressed some "unused variable" warnings from NVHPC that are intended in the unit tests.
Notes
Manually tested with NVHPC 24.9. Ultimately, we should create a separate pipeline for NVHPC in the future.
