#
# Unusual variables checked by this code:
#	NOP - four byte opcode for no-op (defaults to 0)
#	NO_SMALL_DATA - no .sbss/.sbss2/.sdata/.sdata2 sections if not
#		empty.
#	SMALL_DATA_CTOR - .ctors contains small data.
#	SMALL_DATA_DTOR - .dtors contains small data.
#	DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
#	INITIAL_READONLY_SECTIONS - at start of text segment
#	OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
#		(e.g., .PARISC.milli)
#	OTHER_TEXT_SECTIONS - these get put in .text when relocating
#	OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
#		(e.g., .PARISC.global)
#	OTHER_RELRO_SECTIONS - other than .data.rel.ro ...
#		(e.g. PPC32 .fixup, .got[12])
#	OTHER_BSS_SECTIONS - other than .bss .sbss ...
#	OTHER_SECTIONS - at the end
#	EXECUTABLE_SYMBOLS - symbols that must be defined for an
#		executable (e.g., _DYNAMIC_LINK)
#       TEXT_START_ADDR - the first byte of the text segment, after any
#               headers.
#       TEXT_BASE_ADDRESS - the first byte of the text segment.
#	TEXT_START_SYMBOLS - symbols that appear at the start of the
#		.text section.
#	DATA_START_SYMBOLS - symbols that appear at the start of the
#		.data section.
#	DATA_END_SYMBOLS - symbols that appear at the end of the
#		writeable data sections.
#	OTHER_GOT_SYMBOLS - symbols defined just before .got.
#	OTHER_GOT_SECTIONS - sections just after .got.
#	OTHER_SDATA_SECTIONS - sections just after .sdata.
#	OTHER_BSS_SYMBOLS - symbols that appear at the start of the
#		.bss section besides __bss_start.
#	DATA_PLT - .plt should be in data segment, not text segment.
#	PLT_BEFORE_GOT - .plt just before .got when .plt is in data segement.
#	BSS_PLT - .plt should be in bss segment
#	TEXT_DYNAMIC - .dynamic in text segment, not data segment.
#	EMBEDDED - whether this is for an embedded system. 
#	SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set
#		start address of shared library.
#	INPUT_FILES - INPUT command of files to always include
#	WRITABLE_RODATA - if set, the .rodata section should be writable
#	INIT_START, INIT_END -  statements just before and just after
# 	combination of .init sections.
#	FINI_START, FINI_END - statements just before and just after
# 	combination of .fini sections.
#	STACK_ADDR - start of a .stack section.
#	OTHER_END_SYMBOLS - symbols to place right at the end of the script.
#	ETEXT_NAME - name of a symbol for the end of the text section,
#		normally etext.
#	SEPARATE_GOTPLT - if set, .got.plt should be separate output section,
#		so that .got can be in the RELRO area.  It should be set to
#		the number of bytes in the beginning of .got.plt which can be
#		in the RELRO area as well.
#
# When adding sections, do note that the names of some sections are used
# when specifying the start address of the next.
#

#  Many sections come in three flavours.  There is the 'real' section,
#  like ".data".  Then there are the per-procedure or per-variable
#  sections, generated by -ffunction-sections and -fdata-sections in GCC,
#  and useful for --gc-sections, which for a variable "foo" might be
#  ".data.foo".  Then there are the linkonce sections, for which the linker
#  eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
#  The exact correspondences are:
#
#  Section	Linkonce section
#  .text	.gnu.linkonce.t.foo
#  .rodata	.gnu.linkonce.r.foo
#  .data	.gnu.linkonce.d.foo
#  .bss		.gnu.linkonce.b.foo
#  .sdata	.gnu.linkonce.s.foo
#  .sbss	.gnu.linkonce.sb.foo
#  .sdata2	.gnu.linkonce.s2.foo
#  .sbss2	.gnu.linkonce.sb2.foo
#  .debug_info	.gnu.linkonce.wi.foo
#  .tdata	.gnu.linkonce.td.foo
#  .tbss	.gnu.linkonce.tb.foo
#
#  Each of these can also have corresponding .rel.* and .rela.* sections.
