Hi!

I'm getting on both ppc and ppc64 2.125 ulp error on clog10 (> 2ulp
allowed), 0.75ulp on y0 1/8 and 1ulp on imag csinh (-2-3i).

Which gcc are you using? I found that gcc-4.2 or gcc-4.1.1 with the reassociation patch backport causes upls errors in ppc that are not there for just gcc-4.1.1.

I have not had time to tract this down to a simple test case that I can hand to the gcc folks.
