51 The current expression does not correctly handle the case of a
52 text segment ending precisely at the end of a page; it causes the
53 data segment to skip a page. The above expression does not have
54 this problem, but it will currently (2/95) cause BFD to allocate
55 a single segment, combining both text and data, for this case.
56 This will prevent the text segment from being shared among
57 multiple executions of the program; I think that is more
58 important than losing a page of the virtual address space (note
59 that no actual memory is lost; the page which is skipped can not
60 be referenced). */
