1 ## Evaluates the hex writer behavior with empty sections and segments.
2 ##
3 ## Show that the presence of an empty section placed at the same address of a
4 ## filled section doesn't affect the hex output. Also, show that the presence of
5 ## an empty section placed behind the filled section doesn't affect the hex
6 ## output. And, show that this happens regardless of the section ordering in the
7 ## section header table. (Two filled sections, and four empty sections, to
8 ## realize this test.)
9 ##
10 ## Then, show the same kind of behaviors for segments. (One filled section, four
11 ## empty sections, each in a single segment.)
