This is ELFv1 ABI stuff that is still required to get the function working
for PowerPC64 big-endian systems. PowerPC64
From POWER ISA 2.07 B:
- Load Vector Indexed X-form
lvx VRT,RA,RB
.
.
VRT ← MEM(EA & 0x___FFF0, 16)
- Load VSX Vector Doubleword*2 Indexed XX1-form
lxvd2x XT,RA,RB
.
.
VSR[XT]{0:63} ← MEM(EA,8)
VSR[XT]{64:127} ← MEM(EA+8,8)
lxvd2x doesn't set the least significant 4-bit of effective

I think you should reconsider.
Consider, even Andy Polyakov uses lvx/lvsl when loading [potentially]
unaligned buffers on

Thanks.
I've now merged this (squashed together with part 2/3) to the bcrypt
branch in the repository. Before merging to master, I'd need some basic
tests for the testsuite, preferably based on authoritative test

I see.
And I just pushed the change to enable big-endian too.

I tested something similar, I tried to load data at address 0xXXX1
using lxvd2x and it loaded it properly.

I've now committed your docs, in a "Miscellaneous hash functions"
section.

There was a loop over all archs. But I guess I should just remove ppc64
from that list. I was a bit in a hurry to get something working.

Patch implementation benchmark for GCM_AES (Tested on POWER8):
little-endian:
- Encrypt x~17.5 of nettle C implementation
- Decrypt x~17.5 of nettle C implementation
- Update x~30 of nettle C implementation
big-endian:
- Encrypt x~18.5 of nettle C implementation
- Decrypt x~18.5 of nettle C
