floating point emulation

Subject: floating point emulation

Hi,


I am trying to build an embedded system using the GNU tool chain on an
xscale-elf target (Intel PXA255).

When linking the newlib libraries to my code, unfortunately the linker
reports a lot of unresolved low level float function references like
__addf3, __gtdf3, __muldf3, __subdf3 ....

Looking with xscale-elf-objdump into libgcc.a there are obviously a lot of
single and double precision float functions
like _*_df.o and _*_sf.o, but not of the type I need.  

Is there a posibility to use them? 

I rebuild the newlib libraries, but I only got function calls to __adddf3
and so on.
I tried the SoftFloat library , which implements some of the low level
functions, but produces new unresolved references like _udivdi3.

Does anybody has an idea how to solve my problem?


Regards


Uwe
