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#	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.

48# 	combination of .fini sections.
49#	STACK_ADDR - start of a .stack section.
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,
52#		normally etext.
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.
58#
59# When adding sections, do note that the names of some sections are used
60# when specifying the start address of the next.
61#
62
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:
70#
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
86#
87#  Each of these can also have corresponding .rel.* and .rela.* sections.
