# Taken from

#
#   NVCC performs a version check on the host compiler’s major version and so newer minor versions
#   of the compilers listed below will be supported, but major versions falling outside the range
#   will not be supported.
#
# NOTE: These constraints don't apply to Jetson, which uses something else.
# NOTE: NVIDIA can and will add support for newer compilers even during patch releases.
# E.g.: CUDA 12.2.1 maxxed out with support for Clang 15.0; 12.2.2 added support for Clang 16.0.
# NOTE: Because all platforms NVIDIA supports use GCC and Clang, we omit the architectures here.
