* Option names are prefixed with a single dash (\c -).
* Options that take a value have an assignment operator (\c =)
* followed by the option value, with no spaces, e.g. \c "-arch=sm_90".
*
* The supported options are:
* - \c -arch=sm_<N\> \n
* Pass SM architecture value. See nvcc for valid values of <N\>.
* Can use compute_<N\> value instead if only generating PTX.
* This is a required option.
* - \c -maxrregcount=<N\> \n
* Maximum register count.
* - \c -time \n
* Print timing information to InfoLog.
* - \c -verbose \n
* Print verbose messages to InfoLog.
* - \c -lto \n
* Do link time optimization.
* - \c -ptx \n
* Emit ptx after linking instead of cubin; only supported with \c -lto
* - \c -O<N\> \n
* Optimization level. Only 0 and 3 are accepted.
* - \c -g \n
* Generate debug information.
* - \c -lineinfo \n
* Generate line information.
* - \c -ftz=<n\> \n
* Flush to zero.
* - \c -prec-div=<n\> \n
* Precise divide.
* - \c -prec-sqrt=<n\> \n
* Precise square root.
* - \c -fma=<n\> \n
* Fast multiply add.
* - \c -kernels-used=<name\> \n
* Pass list of kernels that are used; any not in the list can be removed.
* This option can be specified multiple times.
* - \c -variables-used=<name\> \n
* Pass list of variables that are used; any not in the list can be removed.
* This option can be specified multiple times.
* - \c -optimize-unused-variables \n
* Normally device code optimization is limited by not knowing what the
* host code references. With this option it can assume that if a variable
* is not referenced in device code then it can be removed.
* - \c -Xptxas=<opt\> \n
* Pass <opt\> to ptxas. This option can be called multiple times.
* - \c -split-compile=<N\> \n
* Split compilation maximum thread count. Use 0 to use all available processors.
* Value of 1 disables split compilation (default).
* - \c -split-compile-extended=<N\> \n
* [Experimental] A more aggressive form of split compilation.
* Accepts a maximum thread count value. Use 0 to use all available processors.
* Value of 1 disables extended split compilation (default).
* - \c -jump-table-density=<N\> \n
* When doing LTO, specify the case density percentage in switch statements,
* and use it as a minimal threshold to determine whether jump table(brx.idx
* instruction) will be used to implement a switch statement. Default
* value is 101. The percentage ranges from 0 to 101 inclusively.
