Same here. I'm just more involved with gcc on targets like SH, sparc64 and m68k. > In fact I'm one of the maintainers of LDC (LLVM D compiler), and I've > bootstrapped the package for armhf/ppc64/ppc64le and working on arm64/powerpc > and > other arches to follow (s390x/mips*) when I have the time.

It first sound like you thought it would be a trivial thing to do. - From my experience, getting compilers work properly can be quite involved on non-mainstream architectures. People are normally used to compilers to be nearly bug free from their experience on x86 targets but that's often not the case on other architectures. On SH, for example, there were over 20 bugs to be fixed until the SH backend for gcc-5 was properly working. > I know for a fact that there are people pushing for IBM to actively support > Rust on ppc64*.

But the question is whether this is endorsed by IBM themselves or just some people working at IBM. Unlike Golang, Rust doesn't have a big usecase which makes it attractive for porters. For Golang, it's container technology and all the projects around it. Nearly every company wants to jump the container hypetrain and that's why Golang is coming to more and more platforms. Plus, Go has a second implementation called gccgo which reaches even more targets. > As with all new languages it will take time, but eventually it will get > there, with a big IF.

The problem with Rust is that there isn't even a stable and fully supported ARM port despite ARM being one of the largest targets Linux runs on. x86 is their only tier 1 architecture, the rest is tier 2 or lower. If Mozilla wants Rust to be a serious competitor to C++, they will have to stack up their resources but I doubt they have the finanical power to do that. They're not Google and their contract with Yahoo will probably not be extended either now that Yahoo has been bought by Verizon. Adrian - -- .''`.
