# Unusual variables checked by this code:
# NOP - four byte opcode for no-op (defaults to none)
# 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_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_RELRO_SECTIONS_2 - as above, but after .dynamic in text segment
# OTHER_BSS_SECTIONS - other than .bss .sbss ...
# ATTRS_SECTIONS - at the end
# OTHER_SECTIONS - at the end
# 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
