We have re-written several of the heavily used routines in libm.a in assembler for the Gould 32/67, 32/97, PN60xx PN90xx machines. Specifically, sqrt(), ldexp() and frexp(). sqrt() is about 10 times faster, and ldexp(), frexp() are MUCH faster than that. If you do lots of f77 stuff (exp, log, etc), these call frexp and ldexp, so their times will be much better too. If you are interested, send E-mail. I would have just posted them, but they are about 4K ofsource, and comments, and the target group is quite small.
