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

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

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.

42 # TEXT_DYNAMIC - .dynamic in text segment, not data segment.
43 # EMBEDDED - whether this is for an embedded system.

53 # OTHER_SYMBOLS - symbols to place right at the end of the script.
54 # ETEXT_NAME - name of a symbol for the end of the text section,
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.
62 # When adding sections, do note that the names of some sections are used
63 # when specifying the start address of the next.
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:
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
90 # Each of these can also have corresponding .rel.* and .rela.* sections.
