AW: Re-port Intent for HPE NonStop (a.k.a. Tandem)

["Joachim Schmitz" <jojo@schmitz-digital.de>]

Hi Florian

No idea whether that port had ever been send back upstream, it must have
been done in 2007 or before.
Not sure what you mean by "stable kernel interface"?
No, sorry, unfortunately no gcc available nor possible to cross-compile, it
is actually the assembler part that is missing IIRC
While gcc may be free (libre) it is also provides quite a few non-standard
features. Our compilers do have some extensions too, but generally are
pretty strictly C89/90, C99 compliant.

Bye, Jojo

It must have been a private port, not released to the general public.

Does HPE NonStop provide a stable kernel interface?  Linux is somewhat
unique in that.  Other systems require some level of synchronization between
libc and kernel updates.

Can you use a GCC cross-compiler?

We need a publicly available, free (libre) toolchain for any port.  This is
both a matter of policy, and also to prevent the port from bit-rotting.

I've removed this section because it is outdated.  I'm not sure if we would
accept ports to new kernels at this point.  (New targets is a different
matter.)

Thanks,
Florian
