Are there efforts to do this for 8-bit processors such as the Z80? Famously they are not very suited for compiling C to because of the limited number of registeres, but LLVM does aggressive register allocation that might make it practical. Edit: Z80 is 8-bit, not 16-bit.

That's an 8-bit CPU.

You might be interested in SDCC, a C compiler that supports Z80, among other small architectures. I'm happy to see it's still actively developed. http://sdcc.sourceforge.net/ http://sdcc.sourceforge.net/

  I have heard of SDCC, but even on small programs such as int main() { return 4; } it generates quite a bit of code. Can it be more optimized?

  SDCC is not especially great.

There's vbcc[0], which, besides 68000, supports a bunch of architectures including 6502 and 6809. [0]: http://www.compilers.de/vbcc.html http://www.compilers.de/vbcc.html

There actually is a Z80 backend for LLVM: > https://github.com/jacobly0/llvm-project https://github.com/jacobly0/llvm-project

  Neat. I've been tempted to try writing a Sharp LR35902 LLVM backend... Probably would be very close to Z80.
