3 # NOP - four byte opcode for no-op (defaults to 0)
4 # NO_SMALL_DATA - no .sbss/.sbss2/.sdata/.sdata2 sections if not
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

17 # OTHER_BSS_SECTIONS - other than .bss .sbss ...
18 # ATTRS_SECTIONS - at the end
19 # OTHER_SECTIONS - at the end
20 # EXECUTABLE_SYMBOLS - symbols that must be defined for an
21 # executable (e.g., _DYNAMIC_LINK)
22 # TEXT_START_ADDR - the first byte of the text segment, after any
24 # TEXT_BASE_ADDRESS - the first byte of the text segment.
25 # TEXT_START_SYMBOLS - symbols that appear at the start of the
27 # DATA_START_SYMBOLS - symbols that appear at the start of the
29 # DATA_END_SYMBOLS - symbols that appear at the end of the
30 # writeable data sections.

32 # OTHER_GOT_SECTIONS - sections just after .got.
33 # OTHER_SDATA_SECTIONS - sections just after .sdata.
34 # OTHER_BSS_SYMBOLS - symbols that appear at the start of the
35 # .bss section besides __bss_start.
36 # DATA_PLT - .plt should be in data segment, not text segment.
37 # PLT_BEFORE_GOT - .plt just before .got when .plt is in data segement.
38 # BSS_PLT - .plt should be in bss segment
39 # TEXT_DYNAMIC - .dynamic in text segment, not data segment.
40 # EMBEDDED - whether this is for an embedded system.
41 # SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set
42 # start address of shared library.
43 # INPUT_FILES - INPUT command of files to always include
44 # WRITABLE_RODATA - if set, the .rodata section should be writable
45 # INIT_START, INIT_END - statements just before and just after
46 # combination of .init sections.

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