I'm trying to learn a bit of ppc assembly. Below is an implementation of
_chacha_core. Seems to work, when tested on gcc112.fsffrance.org (just
put the file in the powerpc64 directory and reconfigure). This machine
is little-endian, I haven't yet tested on big-endian.
Unfortunately I don't get
This is a stand-alone patch that applies all the previous patches to the
optimized GCM implementation. This patch is based on the master upstream so
it can be merged directly.
It passes the testsuite and yields the expected performance.

Some questions on the overall structure:
What's the speedup you get from assembly gcm_fill? I
