pub fn parse_sm_arch(arch: &str) -> Option<SmArch>Expand description
Parse an NVIDIA sm_XY[a|f] architecture string.
Returns None for anything that is not an NVIDIA SM arch — gfx1151
(SCALE/HIP), metal3.1, or junk. None is therefore the “not an NVIDIA
target” marker callers test against.
The digits split NVIDIA’s way: the LAST digit is the minor version, the
rest is the major (sm_90 = 9.0, sm_100 = 10.0, sm_121 = 12.1).
