------- Comment #3 from rask at gcc dot gnu dot org  2007-12-21 22:20 -------
You want something like this in libgcc/config/avr/t-avr to get the 16-bit
versions:

# Extra 16-bit integer functions.
intfuncs16 = _absvXX2 _addvXX3 _subvXX3 _mulvXX3 _negvXX2 _ffsXX2 _clzXX2 \
             _ctzXX2 _popcountXX2
hiintfuncs16 = $(subst XX,hi,$(intfuncs16))
siintfuncs16 = $(subst XX,si,$(intfuncs16))

iter-items := $(hiintfuncs16)
iter-labels := $(siintfuncs16)
iter-sizes := $(patsubst %,2,$(siintfuncs16)) $(patsubst %,2,$(hiintfuncs16))

include $(srcdir)/empty.mk $(patsubst
%,$(srcdir)/siditi-object.mk,$(iter-items))

libgcc-objects += $(patsubst %,%$(objext),$(hiintfuncs16))
ifeq ($(enable_shared),yes)
libgcc-s-objects += $(patsubst %,%_s$(objext),$(hiintfuncs16))
endif
