14 # INITIAL_READONLY_SECTIONS - at start of text segment
15 # OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
16 # (e.g., .PARISC.milli)
17 # OTHER_TEXT_SECTIONS - these get put in .text when relocating
18 # INITIAL_READWRITE_SECTIONS - at start of data segment (after relro)
19 # OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
20 # (e.g., .PARISC.global)
21 # OTHER_RELRO_SECTIONS - other than .data.rel.ro ...
22 # (e.g. PPC32 .fixup, .got[12])
23 # OTHER_RELRO_SECTIONS_2 - as above, but after .dynamic in text segment
24 # OTHER_BSS_SECTIONS - other than .bss .sbss ...
25 # ATTRS_SECTIONS - at the end
26 # OTHER_SECTIONS - at the end
27 # EXECUTABLE_SYMBOLS - symbols that must be defined for an
28 # executable (e.g., _DYNAMIC_LINK)
29 # TEXT_START_ADDR - the first byte of the text segment, after any
31 # TEXT_BASE_ADDRESS - the first byte of the text segment.
32 # TEXT_START_SYMBOLS - symbols that appear at the start of the
34 # DATA_START_SYMBOLS - symbols that appear at the start of the
36 # DATA_END_SYMBOLS - symbols that appear at the end of the
37 # writeable data sections.
38 # OTHER_GOT_SYMBOLS - symbols defined just before .got.
39 # OTHER_GOT_SECTIONS - sections just after .got.
40 # OTHER_SDATA_SECTIONS - sections just after .sdata.
41 # OTHER_BSS_SYMBOLS - symbols that appear at the start of the
42 # .bss section besides __bss_start.
43 # PLT_NEXT_DATA - .plt next to data segment when .plt is in text segment.
44 # DATA_PLT - .plt should be in data segment, not text segment.
45 # PLT_BEFORE_GOT - .plt just before .got when .plt is in data segement.
46 # BSS_PLT - .plt should be in bss segment
47 # NO_REL_RELOCS - Don't include .rel.* sections in script
48 # NO_RELA_RELOCS - Don't include .rela.* sections in script
49 # NON_ALLOC_DYN - Place dynamic sections after data segment.
50 # TEXT_DYNAMIC - .dynamic in text segment, not data segment.
51 # EMBEDDED - whether this is for an embedded system.
52 # SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set
53 # start address of shared library.
54 # INPUT_FILES - INPUT command of files to always include
55 # WRITABLE_RODATA - if set, the .rodata section should be writable
56 # INIT_START, INIT_END - statements just before and just after
57 # combination of .init sections.
58 # FINI_START, FINI_END - statements just before and just after
59 # combination of .fini sections.
60 # STACK_ADDR - start of a .stack section.
61 # OTHER_SYMBOLS - symbols to place right at the end of the script.
62 # ETEXT_NAME - name of a symbol for the end of the text section,
64 # SEPARATE_CODE - if set, .text and similar sections containing
65 # actual machine instructions must be in wholly disjoint
66 # pages from any other data, including headers
67 # SEPARATE_GOTPLT - if set, .got.plt should be separate output section,
68 # so that .got can be in the RELRO area. It should be set to
69 # the number of bytes in the beginning of .got.plt which can be
70 # in the RELRO area as well.
71 # USER_LABEL_PREFIX - prefix to add to user-visible symbols.
72 # RODATA_NAME, SDATA_NAME, SBSS_NAME, BSS_NAME - base parts of names
73 # for standard sections, without initial "." or suffixes.
75 # When adding sections, do note that the names of some sections are used
76 # when specifying the start address of the next.
79 # Many sections come in three flavours. There is the 'real' section,
80 # like ".data". Then there are the per-procedure or per-variable
81 # sections, generated by -ffunction-sections and -fdata-sections in GCC,
82 # and useful for --gc-sections, which for a variable "foo" might be
83 # ".data.foo". Then there are the linkonce sections, for which the linker
84 # eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
85 # The exact correspondences are:
87 # Section Linkonce section
88 # .text .gnu.linkonce.t.foo
89 # .rodata .gnu.linkonce.r.foo
90 # .data .gnu.linkonce.d.foo
91 # .bss .gnu.linkonce.b.foo
92 # .sdata .gnu.linkonce.s.foo
93 # .sbss .gnu.linkonce.sb.foo
94 # .sdata2 .gnu.linkonce.s2.foo
95 # .sbss2 .gnu.linkonce.sb2.foo
96 # .debug_info .gnu.linkonce.wi.foo
97 # .tdata .gnu.linkonce.td.foo
98 # .tbss .gnu.linkonce.tb.foo
99 # .lrodata .gnu.linkonce.lr.foo
100 # .ldata .gnu.linkonce.l.foo
101 # .lbss .gnu.linkonce.lb.foo
103 # Each of these can also have corresponding .rel.* and .rela.* sections.
