7 # Unusual variables checked by this code:
8 # NOP - four byte opcode for no-op (defaults to 0)
9 # NO_SMALL_DATA - no .sbss/.sbss2/.sdata/.sdata2 sections if not
11 # SMALL_DATA_CTOR - .ctors contains small data.
12 # SMALL_DATA_DTOR - .dtors contains small data.
13 # DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
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 # OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
19 # (e.g., .PARISC.global)
20 # OTHER_RELRO_SECTIONS - other than .data.rel.ro ...
21 # (e.g. PPC32 .fixup, .got[12])
22 # OTHER_BSS_SECTIONS - other than .bss .sbss ...
23 # ATTRS_SECTIONS - at the end
24 # OTHER_SECTIONS - at the end
25 # EXECUTABLE_SYMBOLS - symbols that must be defined for an
26 # executable (e.g., _DYNAMIC_LINK)
27 # TEXT_START_ADDR - the first byte of the text segment, after any
29 # TEXT_BASE_ADDRESS - the first byte of the text segment.
30 # TEXT_START_SYMBOLS - symbols that appear at the start of the
32 # DATA_START_SYMBOLS - symbols that appear at the start of the
34 # DATA_END_SYMBOLS - symbols that appear at the end of the
35 # writeable data sections.
36 # OTHER_GOT_SYMBOLS - symbols defined just before .got.
37 # OTHER_GOT_SECTIONS - sections just after .got.
38 # OTHER_SDATA_SECTIONS - sections just after .sdata.
39 # OTHER_BSS_SYMBOLS - symbols that appear at the start of the
40 # .bss section besides ___bss_start.
41 # DATA_PLT - .plt should be in data segment, not text segment.
42 # PLT_BEFORE_GOT - .plt just before .got when .plt is in data segement.
43 # BSS_PLT - .plt should be in bss segment
44 # NO_REL_RELOCS - Don't include .rel.* sections in script
45 # NO_RELA_RELOCS - Don't include .rela.* sections in script
46 # NON_ALLOC_DYN - Place dynamic sections after data segment.
47 # TEXT_DYNAMIC - .dynamic in text segment, not data segment.
48 # EMBEDDED - whether this is for an embedded system.
49 # SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set
50 # start address of shared library.
51 # INPUT_FILES - INPUT command of files to always include
52 # WRITABLE_RODATA - if set, the .rodata section should be writable
53 # INIT_START, INIT_END - statements just before and just after
54 # combination of .init sections.
55 # FINI_START, FINI_END - statements just before and just after
56 # combination of .fini sections.
57 # OTHER_SYMBOLS - symbols to place right at the end of the script.
58 # ETEXT_NAME - name of a symbol for the end of the text section,
60 # SEPARATE_GOTPLT - if set, .got.plt should be separate output section,
61 # so that .got can be in the RELRO area. It should be set to
62 # the number of bytes in the beginning of .got.plt which can be
63 # in the RELRO area as well.
64 # USER_LABEL_PREFIX - prefix to add to user-visible symbols.
66 # When adding sections, do note that the names of some sections are used
67 # when specifying the start address of the next.
70 # Many sections come in three flavours. There is the 'real' section,
71 # like ".data". Then there are the per-procedure or per-variable
72 # sections, generated by -ffunction-sections and -fdata-sections in GCC,
73 # and useful for --gc-sections, which for a variable "foo" might be
74 # ".data.foo". Then there are the linkonce sections, for which the linker
75 # eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
76 # The exact correspondences are:
78 # Section Linkonce section
79 # .text .gnu.linkonce.t.foo
80 # .rodata .gnu.linkonce.r.foo
81 # .data .gnu.linkonce.d.foo
82 # .bss .gnu.linkonce.b.foo
83 # .sdata .gnu.linkonce.s.foo
84 # .sbss .gnu.linkonce.sb.foo
85 # .sdata2 .gnu.linkonce.s2.foo
86 # .sbss2 .gnu.linkonce.sb2.foo
87 # .debug_info .gnu.linkonce.wi.foo
88 # .tdata .gnu.linkonce.td.foo
89 # .tbss .gnu.linkonce.tb.foo
90 # .lrodata .gnu.linkonce.lr.foo
91 # .ldata .gnu.linkonce.l.foo
92 # .lbss .gnu.linkonce.lb.foo
94 # Each of these can also have corresponding .rel.* and .rela.* sections.
