Thanks for a model bug report!
This is clearly a bug in GMP's config.guess.
Do you have any idea about how common this "K8.5" CPU core might be? I
had completely missed its existence. Were they only ever marketed as
"Turion", and only a fraction of the Turions used this core?
I am quite surprised by the nature of the 'make check' failures; if the
compiler is directed by GMP to use unimplemented instructions, I'd
really expect "Illegal instruction" traps, not miscomputations,
segfaults, and hangs!
And in 64-bit mode all works fine. Even more strange.
If you copy some of the failing GMP test cases to a K10 machine, do tey
