|
|
# its own strategy, to wit:
|
|
|
|
#
|
|
|
|
# nvcc recognizes three types of command options: boolean options, single
|
|
|
|
# value options, and list options.
|
|
|
|
#
|
|
|
|
# Boolean options do not have an argument; they are either specified on a
|
|
|
|
# command line or not. Single value options must be specified at most once,
|
|
|
|
# and list options may be repeated. Examples of each of these option types
|
|
|
|
# are, respectively: --verbose (switch to verbose mode), --output-file
|
|
|
|
# (specify output file), and --include-path (specify include path).
|
|
|
|
#
|
|
|
|
# Single value options and list options must have arguments, which must
|
|
|
|
# follow the name of the option itself by either one of more spaces or an
|
|
|
|
# equals character. When a one-character short name such as -I, -l, and -L
|
|
|
|
# is used, the value of the option may also immediately follow the option
|
|
|
|
# itself without being seperated by spaces or an equal character. The
|
|
|
|
# individual values of list options may be separated by commas in a single
|
|
|
|
# instance of the option, or the option may be repeated, or any
|
|
|
|
# combination of these two cases.
|
|
|
|
#
|
|
|
|
# One strange consequence of this choice is that directory and filenames that
|
|
|
|
# contain commas (',') cannot be passed to NVCC (at least, not as easily as
|
|
|
|
# in GCC). Another strange consequence is that it is legal to supply flags
