er of registers that device functions can use. This option is ignored for whole-program compilation and does not affect registers used by entry functions. For device functions, this option overrides the value specified by -maxrregcount option. If neither device-function-maxrregcount nor maxrregcount is specified, then no maximum is assumed.
Note: Under certain situations, static device functions can safely inherit a higher register count from the caller entry function. In such cases, PTXAS may apply the higher count for compiling the static function.
Value less than the minimum registers required by ABI will be bumped up by the compiler to ABI minimum limit.
This option is a BETA feature.
