Thanks for the heads up. FWIW, though, I don't think my changes
help here, because there are no strided loads and stores involved.

I forgot btw: the true solution here is adapt zlib so that the
functions are pluggable and the appropriate calls are made at the
appropriate times based on HW capabilities.
Then throw it at mainline, they may accept it.

Konstantinos is right with regards to the package naming, we discussed
this with the zlib developers at the time.
It is easily solved with a packaging solution though, Provides: as he
said. You will have the same problems with
something libjpegturbo if it forces NEON, or libmatrix shipped with

Konstantinos, Steve,
I think that it depends on how you interpret "plainly mark".I can imagine
several ways of doing this
- Naming the (binary) package explicitly
- install an additional README file / include in the binary package
- explicitly named source tar files
I think that the origi

Yes, you're right

Regarding zlib in particular, in 2005 I had done an altivec port of this,
