I'm confused about what you are talking about now.
I was referring to your suggestion that all calls throughout libm to
__ieee754_sqrt() should be replaced with calls to sqrt() as you think gcc
can optimise it. While this may work for targets with a h/w sqrt
instruction, this will be slower for targets that do not have a sqrt
instruction, as you'll end up with the extra overhead and error handling
code in w_sqrt.c being executed, no?
Cheers,
Jon
