Faster Floating Point Arithmetik for the ATMEL
Floating point routines for addition, subtraction, multiplication are
delivered with the library, e.g from http://download.savannah.gnu.org
There in avr-libc-1.4.5/libm/fplib are the source codes addsf3.s,
mulsf3.s and divsf3.s
HJHerbert replaced these routines by home/cc/lq/_addsf3.s,
home/cc/lq/_mulsf3.s and home/cc/lq/_divsf3.s, which
are compatible and
faster.
