* Fix unrelated MSVC build warnings * Fix use of isnan in functional.h Correct namespace qualification of isnan in functional.h so that it invokes cutlass::isnan for half_t, instead of converting half_t to float and invoking std::isnan (on host, or ::isnan on device).

// CUTLASS_CMATH_NAMESPACE is the namespace where code can find
|
|
// <cmath> functions like isnan and log. Such functions are in
|
|
// the std namespace in host code, but in the global namespace
|
|
// in device code.
|
|
//
|
|
// The intended use case for this macro is in "using" declarations
|
|
// for making argument-dependent lookup (ADL) work in generic code.
|
|
// For example, if T is cutlass::half_t, the following code will
|
|
// invoke cutlass::isnan(half_t). If T is float, it will invoke
|
|
// std::isnan on host and ::isnan on device. (CUTLASS's support
|
|
// for NVRTC prevents it from using things in the std namespace
|
|
// in device code.) Correct use of "using" declarations can help
|
|
// avoid unexpected implicit conversions, like from half_t to float.
