#
# 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.
