[LLVMdev] LLVM on small MCUs?

[John Regehr]

It is really cool that LLVM has a backend for PIC now.  I wonder if 
someone could comment on the suitability of LLVM for 8-bit and 16-bit 
MCUs?  Is there significant impedance mismatch or is it relatively easy to 
get good object code for these platforms?  (I.e. roughly comparable to 
gcc4?)

I ask since gcc is causing significant pain for one of my students.  He 
could switch over to LLVM but only after writing a backend for AVR (8-bit 
RISC).

Thanks,
