I took the required steps. The patch is attached to this email, I hope
I got it right this time. I did not forward the patch to gcc-patches
the first time, sorry for the inconvenience.

Hi.
This patch adds a new optimization to avoid the redundant calculation
tanh(x)/sinh(x) by replacing it for 1.0/cosh(x), for all cases where x is a
double, a long double or a float.
There should be no need for numerical stability testing, since the division
of the two functions only adds numeri
