# Unusual variables checked by this code:
3
#       NOP - four byte opcode for no-op (defaults to 0)
4
#       DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
5
#       OTHER_READONLY_SECTIONS - other than .text .init .ctors .rodata ...
6
#               (e.g., .PARISC.milli)
7
#       OTHER_READWRITE_SECTIONS - other than .data .bss .sdata ...
8
#               (e.g., .PARISC.global)
9
#       OTHER_SECTIONS - at the end
10
#       EXECUTABLE_SYMBOLS - symbols that must be defined for an
11
#               executable (e.g., _DYNAMIC_LINK)
12
#       TEXT_START_SYMBOLS - symbols that appear at the start of the
13
#               .text section.
14
#       DATA_START_SYMBOLS - symbols that appear at the start of the
15
#               .data section.
16
#       OTHER_BSS_SYMBOLS - symbols that appear at the start of the
17
#               .bss section besides __bss_start.
18
#       DATA_PLT - .plt should be in data segment, not text segment.
19
#
20
# When adding sections, do note that the names of some sections are used
21
# when specifying the start address of the next.
