30
#               writeable data sections.
31
#       OTHER_GOT_SYMBOLS - symbols defined just before .got.
32
#       OTHER_GOT_SECTIONS - sections just after .got.

35
#               .bss section besides __bss_start.
36
#       DATA_PLT - .plt should be in data segment, not text segment.
37

42
#       TEXT_DYNAMIC - .dynamic in text segment, not data segment.
43
#       EMBEDDED - whether this is for an embedded system.
44
#       SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set
45
#               start address of shared library.
46
#       INPUT_FILES - INPUT command of files to always include
47
#       WRITABLE_RODATA - if set, the .rodata section should be writable
48
#       INIT_START, INIT_END -  statements just before and just after
49
#       combination of .init sections.
50
#       FINI_START, FINI_END - statements just before and just after

#       combination of .fini sections.
52
#       STACK_ADDR - start of a .stack section.
53
#       OTHER_SYMBOLS - symbols to place right at the end of the script.
54

55
#               normally etext.
56
#       SEPARATE_GOTPLT - if set, .got.plt should be separate output section,
57
#               so that .got can be in the RELRO area.  It should be set to
58
#               the number of bytes in the beginning of .got.plt which can be
59
#               in the RELRO area as well.
60
#       USER_LABEL_PREFIX - prefix to add to user-visible symbols.
61
#
62
# When adding sections, do note that the names of some sections are used
63
# when specifying the start address of the next.
64
#
65
 
66
#  Many sections come in three flavours.  There is the 'real' section,
67
#  like ".data".  Then there are the per-procedure or per-variable
68
#  sections, generated by -ffunction-sections and -fdata-sections in GCC,
69
#  and useful for --gc-sections, which for a variable "foo" might be
70
#  ".data.foo".  Then there are the linkonce sections, for which the linker
71
#  eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
72
#  The exact correspondences are:
73
#
74
#  Section      Linkonce section
75
#  .text        .gnu.linkonce.t.foo
76
#  .rodata      .gnu.linkonce.r.foo
77
#  .data        .gnu.linkonce.d.foo
78
#  .bss         .gnu.linkonce.b.foo
79
#  .sdata       .gnu.linkonce.s.foo
80
#  .sbss        .gnu.linkonce.sb.foo
81
#  .sdata2      .gnu.linkonce.s2.foo
82
#  .sbss2       .gnu.linkonce.sb2.foo
83
#  .debug_info  .gnu.linkonce.wi.foo
84
#  .tdata       .gnu.linkonce.td.foo
85
#  .tbss        .gnu.linkonce.tb.foo
86
#  .lrodata     .gnu.linkonce.lr.foo
87
#  .ldata       .gnu.linkonce.l.foo
88
#  .lbss        .gnu.linkonce.lb.foo
89
#
90
#  Each of these can also have corresponding .rel.* and .rela.* sections.
