  /* Adjust the address for the data segment.  We want to adjust up to

     the same address within the page on the next page up.  It would

     be more correct to do this:
69
       . = ALIGN(0x40000) + (ALIGN(8) & (0x40000 - 1));
70
     The current expression does not correctly handle the case of a
71
     text segment ending precisely at the end of a page; it causes the
72
     data segment to skip a page.  The above expression does not have
73
     this problem, but it will currently (2/95) cause BFD to allocate
74
     a single segment, combining both text and data, for this case.
75
     This will prevent the text segment from being shared among
76
     multiple executions of the program; I think that is more
77
     important than losing a page of the virtual address space (note
78
     that no actual memory is lost; the page which is skipped can not
79
     be referenced).  */
