=== Cut ===
static const double coeff[] = { 1.0l/42 };

gives:

------- Comment #1 from pinskia at gcc dot gnu dot org 2006-02-19 22:01 -------
This is actually because the middle-end does not constant fold 128bit IBM long
double. I am assuming you are using -mlong-double-128.

I'm not sure 1.0l/42 is a valid constant initializer.

hmm, I guess I'm find with resolving this as duplicate to 19779, even though I
don't understand why this is only an issue on PPC for me..

It is because the long double format used on PPC is IBM's 128bit long double
which is two doubles basicially added together.

> Any progress on this?
There are two way of fixing this as far as I can see:
teach real.c about how to fold IBM 128bit long double format
use MPFR instead
I would use the latter if I got any time but I don't have any time to do
either.
