+# Unusual variables checked by this code:
+# NOP - four byte opcode for no-op (defaults to 0)ALIGN
+# 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.
+# 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.
+# 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.
