#	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)
#	ATTRS_SECTIONS - at the end
#	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

#	OTHER_BSS_SYMBOLS - symbols that appear at the start of the

#
# When adding sections, do note that the names of some sections are used
# when specifying the start address of the next.

     data segment to skip a page.  The above expression does not have
     this problem, but it will currently (2/95) cause BFD to allocate
     a single segment, combining both text and data, for this case.
     This will prevent the text segment from being shared among
     multiple executions of the program; I think that is more
     important than losing a page of the virtual address space (note
     that no actual memory is lost; the page which is skipped can not
