Re: Sparc status ?

I really don't understand why this "32-bit gone" myth is happening. It
was poor wording at least. Debian doesn't even support the ancient
32-bit sparc CPUs. Modern SPARC ABIs (post 1997) require 64-bit CPUs
even when running in 32-bit code, it's like x32 ABI in x86 land.
Debian sparc userland is v8+. It only is usable on v9 CPU, not v8. I
have reinstalled all my old sparc v8 under NetBSD.
SPARCv7, SPARCv8 = old 32-bit CPUs, Linux kernel barely supports them now
You have forgotten Leon CPU that are v8e (32 bits), not v8+ or v9.
SPARCv9 = modern (post 1997) 64-bit CPUs, Linux and GCC supports them
just fine.
There are some bugs in userland (mainly due to endianess).
