# as a fallback for hardware configurations for which the hand-coded
# assembly support is incomplete, i.e., where there is no NORM and/or no
# supported multiply instruction.  Using floating point on such a
# configuration is generally inadvisable, but we got to provide support
# somehow so that we can run the testsuites.
# fp-hack.h / dp-hack.h take care of slecting the parts that are needed,
# and (for debugging) of renaming functions so that they can be
# used in an asm wrapper.
