The period (.) is a special symbol reserved to denote the current offset of
the location counter. It is useful in address expressions to refer to a
location relative to the current instruction or data word. This symbol is
considered relocatable, and can be used anywhere a relocatable symbol
can be used, with the exception of the label field.
The period cannot be used in an expression involving another label, such
as sym+., sym-., .+sym, or .-sym. It can be used in an expression that
has only a constant, such as .+8 or .-8.
