   For building Linux, you mean? I don't know whether that's the case, but I wouldn't be surprised. LLVM is missing some of the targets that Linux supports, so Linux people are probably going to want to use a Rust compiler that uses GCC as a backend (either rustc_codegen_gcc or gcc-rs) once it's sufficiently mature.

   As of this moment, though, they're using the LLVM-based rustc, according to their documentation.

     @wolf480pl @argv_minus_one @puppygirlhornypost2 @pancake Wikipedia lists the Motorola 68000 as discontinued in 1996. I would firmly count that into the historical context. Wikipedia has nothing on C sky... does not look like a major player.

     Are these seriously the two architectures we absolutely need gcc for?

     No.

     These are *a* two architectures.

     There's also SuperH, DEC Alpha, PARISC, OpenRISC, MicroBlaze, Xtensa, ARC, NIOS II.

     I do not know which of those are still being used in some embedded systems. The kernel maintainers for those architectures probably know, you'd have to ask them.

     Motorola 68k is still alive: https://en.wikipedia.org/wiki/NXP_ColdFire

     You can buy those chips today:

     @argv_minus_one @puppygirlhornypost2 @pancake @wolf480pl I keep hearing that gcc supports more targets than LLVM, and I do notmdoubt that. But can you name one such target that is still relevant outside of a historical context.

     Anything that has vague community or commercial backing has a LLVM target by now.

     @hunger @argv_minus_one @puppygirlhornypost2 @pancake
     m68k seems to be still in use in some embedded systems and getting fixes for those:

     https://github.com/torvalds/linux/commit/a0a8306c823986c43ea58be13e8b366999a93cb2

     Also, there's c-sky which is a pretty new architecture.

     LLVM seems to have backends for those two in some shape or form, but not enough to build Linux for those architectures with clang:

     @wolf480pl @argv_minus_one @puppygirlhornypost2 @pancake So basically architectures that can not effort to have support in LLVM because either the commercial interest by its vendors is too small or there is no more vendor.

     So nothing you can build on in earnest todays... just historical interest.

     I'm pretty sure there is work on adding supoport for half of those to LLVM.

     Also, by your logic, NVidia is of historical interest.
