@item Report
The state of the option should be printed by @option{-fverbose-asm}.
@item Warning
This is a warning option and should be shown as such in
@option{--help} output. This flag does not currently affect anything
other than @option{--help}.
@item Optimization
This is an optimization option. It should be shown as such in
@option{--help} output, and any associated variable named using
@code{Var} should be saved and restored when the optimization level is
changed with @code{optimize} attributes.
@item Undocumented
The option is deliberately missing documentation and should not
be included in the @option{--help} output.
