Here you go for gmpbench w/ -O2 -m64 (attached as RES.O2)

NOTE : gmp itself doesn't seem to compile with -O3 (this is still on the
same opteron box) :

beaufort : ...mp-4.1.4/mpz $ gcc -I.. -O3 -c n_pow_ui.c  
n_pow_ui.c: In function `__gmpz_n_pow_ui':
n_pow_ui.c:521: error: extended registers have no high halves

The offending line is the asm statement from the expansion of
ULONG_PARITY (from line 484 in n_pow_ui.c) :

asm("xorb   %h1, %b1\n" "setpo  %0\n": "=qm"(__p), "=q"(__n):"1"(__n));

( %h1 seems like unwanted on x86-64 ; why this very thing _passes_ with
-O2 is bizarre to me. )

With the generic C code itself, the compile goes OK. The corresponding
bench output is in RES.O3

Makes sense.
