yes.  John, can you, from gdb, print the value of
OPENSSL_sparcv9cap_P[0] and OPENSSL_sparcv9cap_P[1].  if 1<<6 is set
in the first, then the vis3 path will be taken in gcm_ghash_4bit().

it seems that these caps are setup wrongly.  you could try to
instrument OPENSSL_cpuid_setup() in 
crypto/external/bsd/openssl/dist/crypto/sparcv9cap.c to print the
various settigs.  it seems that SPARCV9_VIS3 is set.  note that
there are two places it can be set, but the first one is only for
_SVR4 so not used here.

nothing here seems changed with the update.  these values should
all be zero for real sparc 32 bit hardware (they're the sparcv9
caps after all :)

good idea.
