It would be platform suicide to drop 32-bit code generation. Like many RISC architectures, switching to 64-bit is only done for apps that need it, because it is not free and will not, in general, make apps faster. Anyone who has worked on PPC, MIPS, SPARC, etc will be able to confirm this in a heartbeat, and no doubt gcc-sparc maintainers are aware of this as well.

So this does not really help to understand why the switch to gcc-4.8 didn't happened on the sparc architecture.

Because GCC maintainers have been saying for years, that they are unwilling to support the weird use case of Debian sparc port, which has 64-bit kernel but 32-bit userspace. I can find discussions about it going back as far as 2009:

https://lists.debian.org/debian-sparc/2009/08/msg00010.html

Another possibly relevant bit is that Aurelien Jarno started working on an unofficial sparc64 port a while ago, but the current status of it is unknown to me. See, for example

https://wiki.debian.org/Sparc64

 

Cheers.
