#
# Unusual variables checked by this code:
# NOP - four byte opcode for no-op (defaults to 0)
# DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
# OTHER_READONLY_SECTIONS - other than .text .init .ctors .rodata ...
# (e.g., .PARISC.milli)
# OTHER_READWRITE_SECTIONS - other than .data .bss .sdata ...
# (e.g., .PARISC.global)
# OTHER_SECTIONS - at the end
# EXECUTABLE_SYMBOLS - symbols that must be defined for an
# executable (e.g., _DYNAMIC_LINK)
# 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_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.
#
# When adding sections, do note that the names of some sections are used
# when specifying the start address of the next.
