@ -340,19 +340,6 @@ The state of this option should be stored in variable @var{var}
(actually a macro for @code{global_options.x_@var{var}}).
The way that the state is stored depends on the type of option:
@item WarnRemoved
The option is removed and every usage of such option will
result in a warning. We use it option backward compatibility.
@item Var(@var{var}, @var{set})
The option controls an integer variable @var{var} and is active when
@var{var} equals @var{set}. The option parser will set @var{var} to
@var{set} when the positive form of the option is used and @code{!@var{set}}
when the ``no-'' form is used.
@var{var} is declared in the same way as for the single-argument form
described above.

The option-processing script will usually zero-initialize @var{var}.
You can modify this behavior using @code{Init}.
@item Var(@var{var}, @var{set})
The option controls an integer variable @var{var} and is active when
@var{var} equals @var{set}. The option parser will set @var{var} to

@var{var} is declared in the same way as for the single-argument form

@item Init(@var{value})
The variable specified by the @code{Var} property should be statically
initialized to @var{value}. If more than one option using the same
variable specifies @code{Init}, all must specify the same initializer.
@item WarnRemoved
The option is removed and every usage of such option will
result in a warning. We use it option backward compatibility.
@item Mask(@var{name})
The option is associated with a bit in the @code{target_flags}
variable (@pxref{Run-time Target}) and is active when that bit is set.
