Dear all,
now that my copyright assignment is ok, you'll find on [1] a first contribution
that adds some inputs that yield larger errors for the float (binary32) type on
x86_64. These cases were generated by exhaustive search using MPFR, thus the
corresponding bounds are now definitive (on x86_64 only of course).
For those functions where no case was added, this means the previous bounds
were the largest ones.
This exhaustive search only concerns functions with one argument. It does not
cover functions like pow(x,y) or hypot(x,y) where exhaustive search would be
too expensive.
I would be grateful if someone could review that contribution.

Verified 13 output files updated. Verified ULPs seem reasonable. Verified libm-test-ulps seems reasonable. Looks good to me. I'd like to see Joseph give this quick review also before committing. You don't say why you limit j*/y* functions to ULP <=9, but I expect the implied intent is to avoid using such a high ULP value that it hides other genuine bugs.

Things pass if I drop the y1 value e.g. 0x1.f7e5dcp+0. I don't think we can reliably add y1. I can push your patch without the y1 value, tell me if that works for you. See the attached patch.
