# The CUDA Toolkit Documentation, in 4.1. Command Option Types and Notation, |
|
# specifies that NVCC does not parse the standard flags as GCC does. It has |
|
# 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 separated 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 |
|
# such as |
|
# |
|
# -lpthread,rt,dl,util |
|
# -l pthread,rt,dl,util |
|
# -l=pthread,rt,dl,util |

# |

# -l=pthread -l=rt -l=dl -l=util |

# is a strict subset of NVCC-speak, so we passthrough those flags. |

# |
|
# The -D macro-define flag is documented as somehow shielding commas from |
|
# splitting a definition. Balanced parentheses, braces and single-quotes |
|
# around the comma are not sufficient, but balanced double-quotes are. The |
|
# shielding appears to work with -l, -I, -L flags as well, for instance. |

# |

# Since our goal is to replicate GCC-speak as much as possible, we check for |
