   2 # Unusual variables checked by this code:
   3 #       NOP - four byte opcode for no-op (defaults to 0)
   4 #       NO_SMALL_DATA - no .sbss/.sbss2/.sdata/.sdata2 sections if not
   5 #               empty.
   6 #       SMALL_DATA_CTOR - .ctors contains small data.
   7 #       SMALL_DATA_DTOR - .dtors contains small data.
   8 #       DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
   9 #       INITIAL_READONLY_SECTIONS - at start of text segment
  10 #       OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
  11 #               (e.g., .PARISC.milli)
  12 #       OTHER_TEXT_SECTIONS - these get put in .text when relocating
  13 #       OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
  14 #               (e.g., .PARISC.global)
  15 #       OTHER_RELRO_SECTIONS - other than .data.rel.ro ...
  16 #               (e.g. PPC32 .fixup, .got[12])
  17 #       OTHER_BSS_SECTIONS - other than .bss .sbss ...
  18 #       OTHER_SECTIONS - at the end
  19 #       EXECUTABLE_SYMBOLS - symbols that must be defined for an
  20 #               executable (e.g., _DYNAMIC_LINK)
  21 #       TEXT_START_ADDR - the first byte of the text segment, after any
  22 #               headers.
  23 #       TEXT_BASE_ADDRESS - the first byte of the text segment.
  24 #       TEXT_START_SYMBOLS - symbols that appear at the start of the
  25 #               .text section.
  26 #       DATA_START_SYMBOLS - symbols that appear at the start of the
  27 #               .data section.
  28 #       OTHER_GOT_SYMBOLS - symbols defined just before .got.
  29 #       OTHER_GOT_SECTIONS - sections just after .got.
  30 #       OTHER_SDATA_SECTIONS - sections just after .sdata.
  31 #       OTHER_BSS_SYMBOLS - symbols that appear at the start of the
  32 #               .bss section besides __bss_start.
  33 #       DATA_PLT - .plt should be in data segment, not text segment.
  34 #       PLT_BEFORE_GOT - .plt just before .got when .plt is in data segement.
  35 #       BSS_PLT - .plt should be in bss segment
  36 #       TEXT_DYNAMIC - .dynamic in text segment, not data segment.
  37 #       EMBEDDED - whether this is for an embedded system.
  38 #       SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set
  39 #               start address of shared library.
  40 #       INPUT_FILES - INPUT command of files to always include
  41 #       WRITABLE_RODATA - if set, the .rodata section should be writable
  42 #       INIT_START, INIT_END -  statements just before and just after
  43 #       combination of .init sections.
  44 #       FINI_START, FINI_END - statements just before and just after
  45 #       combination of .fini sections.
  46 #       STACK_ADDR - start of a .stack section.
  47 #       OTHER_END_SYMBOLS - symbols to place right at the end of the script.
  48 #       SEPARATE_GOTPLT - if set, .got.plt should be separate output section,
  49 #               so that .got can be in the RELRO area.  It should be set to
  50 #               the number of bytes in the beginning of .got.plt which can be
  51 #               in the RELRO area as well.
  52 #
  53 # When adding sections, do note that the names of some sections are used
  54 # when specifying the start address of the next.
  55 #
  56
  57 #  Many sections come in three flavours.  There is the 'real' section,
  58 #  like ".data".  Then there are the per-procedure or per-variable
  59 #  sections, generated by -ffunction-sections and -fdata-sections in GCC,
  60 #  and useful for --gc-sections, which for a variable "foo" might be
  61 #  ".data.foo".  Then there are the linkonce sections, for which the linker
  62 #  eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
  63 #  The exact correspondences are:
  64 #
  65 #  Section      Linkonce section
  66 #  .text        .gnu.linkonce.t.foo
  67 #  .rodata      .gnu.linkonce.r.foo
  68 #  .data        .gnu.linkonce.d.foo
  69 #  .bss         .gnu.linkonce.b.foo
  70 #  .sdata       .gnu.linkonce.s.foo
  71 #  .sbss        .gnu.linkonce.sb.foo
  72 #  .sdata2      .gnu.linkonce.s2.foo
  73 #  .sbss2       .gnu.linkonce.sb2.foo
  74 #  .debug_info  .gnu.linkonce.wi.foo
  75 #  .tdata       .gnu.linkonce.td.foo
  76 #  .tbss        .gnu.linkonce.tb.foo
  77 #
  78 #  Each of these can also have corresponding .rel.* and .rela.* sections.
