+#	DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
+#	OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
+#		(e.g., .PARISC.milli)
+#	OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .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.
