# Unusual variables checked by this code:
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
#       ATTRS_SECTIONS - at the end
12
#       OTHER_SECTIONS - at the end
13
#       EXECUTABLE_SYMBOLS - symbols that must be defined for an
14
#               executable (e.g., _DYNAMIC_LINK)
15
#       TEXT_START_SYMBOLS - symbols that appear at the start of the
16
#               .text section.
17
#       DATA_START_SYMBOLS - symbols that appear at the start of the
18
#               .data section.
19
#       OTHER_BSS_SYMBOLS - symbols that appear at the start of the
20
#               .bss section besides __bss_start.
21
#
22
# When adding sections, do note that the names of some sections are used
23
# when specifying the start address of the next.

  /* 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

102
       ${RELOCATING+. = ${DATA_ADDR-ALIGN(${MAXPAGESIZE}) + (ALIGN(8) & (${MAXPAGESIZE} - 1))};}
103
     The current expression does not correctly handle the case of a
104
     text segment ending precisely at the end of a page; it causes the
105
     data segment to skip a page.  The above expression does not have
106
     this problem, but it will currently (2/95) cause BFD to allocate
107
     a single segment, combining both text and data, for this case.
108
     This will prevent the text segment from being shared among
109
     multiple executions of the program; I think that is more
110
     important than losing a page of the virtual address space (note
111
     that no actual memory is lost; the page which is skipped can not
112
     be referenced).  */
