#
2
# Unusual variables checked by this code:
3
#       NOP - four byte opcode for no-op (defaults to 0)
4
#       DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
5
#       INITIAL_READONLY_SECTIONS - at start of data segment
6
#       OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
7
#               (e.g., .PARISC.milli)
8
#       OTHER_TEXT_SECTIONS - these get put in .text when relocating
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_GOT_SYMBOLS - symbols defined just before .got.
19
#       OTHER_GOT_SECTIONS - sections just after .got.
20
#       OTHER_SDATA_SECTIONS - sections just after .sdata.
21
#       OTHER_BSS_SYMBOLS - symbols that appear at the start of the
22
#               .bss section besides __bss_start.
23
#       DATA_PLT - .plt should be in data segment, not text segment.
24
#       BSS_PLT - .plt should be in bss segment
25
#       TEXT_DYNAMIC - .dynamic in text segment, not data segment.
26
#       EMBEDDED - whether this is for an embedded system.
27
#       SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set
28
#               start address of shared library.
29
#       INPUT_FILES - INPUT command of files to always include
30
#       WRITABLE_RODATA - if set, the .rodata section should be writable
31
#       INIT_START, INIT_END -  statements just before and just after
32
#       combination of .init sections.
33
#       FINI_START, FINI_END - statements just before and just after
34
#       combination of .fini sections.
35
#
36
# When adding sections, do note that the names of some sections are used
37
# when specifying the start address of the next.
38
#
39
 
40
#  Many sections come in three flavours.  There is the 'real' section,
41
#  like ".data".  Then there are the per-procedure or per-variable
42
#  sections, generated by -ffunction-sections and -fdata-sections in GCC,
43
#  and useful for --gc-sections, which for a variable "foo" might be
44
#  ".data.foo".  Then there are the linkonce sections, for which the linker
45
#  eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
46
#  The exact correspondences are:
47
#
48
#  Section      Linkonce section
49
#  .text        .gnu.linkonce.t.foo
50
#  .rodata      .gnu.linkonce.r.foo
51
#  .data        .gnu.linkonce.d.foo
52
#  .bss         .gnu.linkonce.b.foo
53
#  .sdata       .gnu.linkonce.s.foo
54
#  .sbss        .gnu.linkonce.sb.foo
55
#  .sdata2      .gnu.linkonce.s2.foo
56
#  .sbss2       .gnu.linkonce.sb2.foo
57
#
58
#  Each of these can also have corresponding .rel.* and .rela.* sections.
