JR		 1#
2# Unusual variables checked by this code:
3# NOP - four byte opcode for no-op (defaults to 0)
4# NO_SMALL_DATA - no .sbss/.sbss2/.sdata/.sdata2 sections if not
5# empty.
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
13# OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
14# (e.g., .PARISC.global)
15# OTHER_RELRO_SECTIONS - other than .data.rel.ro ...
16# (e.g. PPC32 .fixup, .got[12])
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
23# headers.
24# TEXT_BASE_ADDRESS - the first byte of the text segment.
25# TEXT_START_SYMBOLS - symbols that appear at the start of the
26# .text section.
27# DATA_START_SYMBOLS - symbols that appear at the start of the
28# .data section.
29# DATA_END_SYMBOLS - symbols that appear at the end of the
30# writeable data sections.
31# OTHER_GOT_SYMBOLS - symbols defined just before .got.
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# NO_REL_RELOCS - Don't include .rel.* sections in script
40# NO_RELA_RELOCS - Don't include .rela.* sections in script
41# NON_ALLOC_DYN - Place dynamic sections after data segment.
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
51# 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# ETEXT_NAME - name of a symbol for the end of the text section,
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.
