Re: Upcoming changes to supported architectures

Why do I see a deja-vue? I think we had this already some years ago.

The sh* ports are not dead? I've not seen anything from them for years.
Also from the kernel point of view, there are sh2, 3, 4 and 5, the
first three as both little and big endian. And when it goes for the
compiler it only gets worse, it lists 23 multilib variants.

There is some. IBM likes to add new op-codes to every processor release
and with a higher minimum supported type they can be used. They often
provide a speed benefit. Also the instruction format is identical
between the 31 and 64bit code. I would like to use multiarch, but this
is still not ready.
