Slower pipeline in Athlon X2?

[Torbjorn Granlund]

It has been reported to me that the Athlon X2 core runs GMP loops
slower than single core Athlon 64.

Can people on this list that have access to X2 system please
build the tune/speed utility and run this test, and send me the
results:

 cd tune
 make speed
 ./speed -C -s1-10000 -f1.14 mpn_addmul_1.0xbadcafebabe

Please also state your operating system as reported by "uname -a".
