Writing a option pass

[albino aiello]

Thank you,
my problem is that the value of the variable that i have defined in 
common.opt in the following manner is always at the default value:

myvariable=
Common RejectNegative UInteger Var (my_variable) Init(-1)
Comments

In passes.c i have defined a new compilation pass that must use the 
value stored in myvariable that is always -1.
I think that maybe i wrong when write the compilation command. I have 
try in different ways like:

gcc -my-passes -myvariable=number
gcc -my-passes -myvariable='number'
gcc -my-passes -myvariable=[number]
gcc -my-passes -myvariable="number"

I don't know the just way.
Can you give some suggestion??

Thanks.
