2# 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.
