Well, Factory is building packages for ppc, ppc64 and ppc64le so it's not so relevant at the moment that there are no Tumbleweed releases for 32-bit PowerPC:
Isn't the ppc target more or less just an ILP32 variant of a ppc64 anyway, similar to what x32 is to x86_64?
It's a different instruction set. x32 is basically x86_64 with 32-bit pointers with the full x86_64 instruction set available. 32-bit PowerPC is the PowerPC 74xx series (based on the POWER3 ISA IIRC) while 64-bit PowerPC is the 970 series (based on the POWER4 ISA).
For 32-bit SPARC, people usually use SPARCv9 (the first 64-bit UltraSPARC) with 32-bit pointers. So it's very much comparable with x32 and x86_64.
That last part has always been a bit strange, because sparc64-linux-gcc -m32 does not actually make use of the basic 64-bit instructions like ldx/stx, noticable for example when playing with uint64_t-based time. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
