Parser::setOptions is called by Parser::load (load2.cc), called by the
Analysis constructor, reading option values specified in an Analysis:
specification in, e.g., the 'analysis' file passed as argument to simrisc.
Parser::setOptions fills the Parser::OptionsVect with the long option names
and specified values. Then OptionsVect is passed to Analysis::actualize called
from the Analysis constructor.
Analysis::actualize first calls
Options::activate, which assigns the STARTUP option values (which are the
specified option values (or the default option values if not specified))
to the ANALYSIS elements. This happens at each analysis, so each analysis
starts with the original set op option values. The actually specified
options are made available in d_specified[ANALYSIS]: those options cannot
be altered by 'Analysis:' specfications.
Next, all the long option names specified in the optionVect are looked up
in g_longOptions. If longOptions contains an option specified in
g_longOptions then its short option equivalent and sp
Each option specified in the OptionsVect is looked up in the global
Args::LongOptions g_longOpts vector (defined in main.cc).
If a long option is found then Options::alter is called with the optionChar
and the configured value.
Options::alter checks whether the option was specified as a comman-line option
when simrisc was called, if so it returns false, resulting in a warning
msg. that the specification is ignored.
Once all options have been processed Options::actualize is called to set the
current ANALYSIS option values, and to set the simulation type used in this
analysis.
