Please go to http://sourceware.cygnus.com/glibc/ and look
libc/soft-fp directory and libc/sysdeps/i386/sfp-machine.h
in their cvs resources. You can use their cvsweb interface
to access these files even if you can not use cvs command
directly. I'm not sure whether they are what you want or not
and I don't know how to use them, but there are functions
like __muldf3, __adddf3 and so on.
