+# NOP - four byte opcode for no-op (defaults to none)
# NO_SMALL_DATA - no .sbss/.sbss2/.sdata/.sdata2 sections if not
# empty.
# SMALL_DATA_CTOR - .ctors contains small data.
# OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
# (e.g., .PARISC.milli)
# OTHER_TEXT_SECTIONS - these get put in .text when relocating
+# INITIAL_READWRITE_SECTIONS - at start of data segment (after relro)

+# OTHER_BSS_SECTIONS - other than .bss .sbss ...
+# ATTRS_SECTIONS - at the end
# OTHER_SECTIONS - at the end
# EXECUTABLE_SYMBOLS - symbols that must be defined for an
# executable (e.g., _DYNAMIC_LINK)
# OTHER_SDATA_SECTIONS - sections just after .sdata.
# OTHER_BSS_SYMBOLS - symbols that appear at the start of the
# .bss section besides __bss_start.
+# PLT_NEXT_DATA - .plt next to data segment when .plt is in text segment.
# 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
+# NO_REL_RELOCS - Don't include .rel.* sections in script
+# NO_RELA_RELOCS - Don't include .rela.* sections in script
+# NON_ALLOC_DYN - Place dynamic sections after data segment.
# TEXT_DYNAMIC - .dynamic in text segment, not data segment.
-# EMBEDDED - whether this is for an embedded system.
+# 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
# OTHER_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_CODE - if set, .text and similar sections containing
+# actual machine instructions must be in wholly disjoint
+# pages from any other data, including headers
# 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

# in the RELRO area as well.
+# USER_LABEL_PREFIX - prefix to add to user-visible symbols.

#
# When adding sections, do note that the names of some sections are used

# Each of these can also have corresponding .rel.* and .rela.* sections.
