2.4 Compiler options

2.4.2 Kinds of options

Vortex has four classes of options:

Boolean options (e.g., optimize, show_phases). They can have true and false as values.

Integer options (e.g., opt_verbosity_level). Their values are integers.

String options (e.g., gen_dir). Their values are strings. When changing their values, the double quotes around the new string value (that would be required by the Cecil syntax) should be omitted. To set a string option to the empty string, use set optname (with no explicit option value, i.e., the empty string).

String list options (e.g., source_paths). Their values are lists of strings. When changing the value of a string list option, the new value is the list of words that are separated by spaces in the user's command. As with string options, the quotes around the strings should be omitted, and set optname sets an option to the empty list.

String and string list options allow prepend and append operations:
