   5 #       NOP - four byte opcode for no-op (defaults to 0)
   6 #       DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
   7 #       OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
   8 #               (e.g., .PARISC.milli)
   9 #       OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
  10 #               (e.g., .PARISC.global)
  11 #       OTHER_SECTIONS - at the end
  12 #       EXECUTABLE_SYMBOLS - symbols that must be defined for an
  13 #               executable (e.g., _DYNAMIC_LINK)
  14 #       TEXT_START_SYMBOLS - symbols that appear at the start of the
  15 #               .text section.
  16 #       DATA_START_SYMBOLS - symbols that appear at the start of the
  17 #               .data section.
  18 #       OTHER_BSS_SYMBOLS - symbols that appear at the start of the
  19 #               .bss section besides __bss_start.

 101      The current expression does not correctly handle the case of a
 102      text segment ending precisely at the end of a page; it causes the
 103      data segment to skip a page.  The above expression does not have
 104      this problem, but it will currently (2/95) cause BFD to allocate
 105      a single segment, combining both text and data, for this case.
 106      This will prevent the text segment from being shared among
 107      multiple executions of the program; I think that is more
 108      important than losing a page of the virtual address space (note
 109      that no actual memory is lost; the page which is skipped can not
 110      be referenced).  */
