Flat annotation definitions (see section Flat Annotations) are represented by
base annote_def objects, for which the is_structured
method returns FALSE. Other than the annotation name, these
entries contain a flag that indicates whether the annotations should be
written to the SUIF output file. The output method is used to
retrieve this flag and the set_output method to change its value.
The ANNOTE macro provides a convenient way to register flat
annotations. This macro enters the annotation name in the
lexicon, creates an annote_def object, and registers it
with the manager. It takes three arguments: the variable that will hold
the pointer to the annotation name in the lexicon, the annotation
name, and the value of its output flag. For example:
char *k_my_annote; ANNOTE(k_my_annote, "my_annote", TRUE);
This enters the name "my_annote" in the lexicon and sets
k_my_annote to point to that string. It also registers that name
as a flat annotation that will be written to the SUIF output file.
Typically, k_my_annote will be a global variable that is used
throughout the program to refer to annotations of this type.
