I happen to have an old POWER3 AIX box available.

I got tired of waiting for a fsck --full to complete on the git repo,
so I used git://anongit.freedesktop.org/git/xcb/libxcb instead. Best
of five runs:

OpenSSL:
$ time ../git-1.6.4.1/git fsck --full

real    0m4.120s
user    0m3.776s
sys     0m0.031s

BLK_SHA1:
$ time ../git-blk/git fsck --full

real    0m4.231s
user    0m3.867s
sys     0m0.026s

PPC_SHA1:

    CC ppc/sha1ppc.o
Assembler:
/tmp//ccdODWpe.s: line 8: 1252-142 Syntax error.
/tmp//ccdODWpe.s: line 9: 1252-142 Syntax error.
[same error repeated 42 times]
gmake: *** [ppc/sha1ppc.o] Error 1

Hmm. So that may not help so much after all. Let me know if there are
any other tests you would like me to run.

This machine has:
$ gcc --version
gcc (GCC) 3.3.2

$ as -v
as V5.3

$ lsattr -E -l proc0
frequency   200000000      Processor Speed       False
smt_enabled false          Processor SMT enabled False
smt_threads 0              Processor SMT threads False
state       enable         Processor state       False
type        PowerPC_POWER3 Processor type        False
