# 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.
