/* $Id: //info.ravenbrook.com/project/mps/master/test/test/testlib/rankfmt.h#5 $
Format like exfmt but with rank-checking built in.
This format will work without register roots, but to use it, you must
take precautions. You must register exfmt_root as a root, and unless
you register the registers and stack, you must register it as
ambiguous (or it might change before you can write the address of a
newly allocated object into another root). When you call getref or
setref, you must make sure that the objects concerned are referenced
ambiguously somewhere (this guarantees that they won't move -- I
asked richard and drj).
