Dear George,

One more question, I have to gotta home :) why the Type of relocation by avr-gcc and `clang --target=avr` is different?

  readelf -r avr-gcc-BareMinimum.o
  
  Relocation section '.rela.text' at offset 0x1d0 contains 2 entries:
   Offset     Info    Type            Sym.Value  Sym. Name + Addend
  00000000  00000d03 R_AVR_13_PCREL    00000000   bar + 0
  00000002  00000e03 R_AVR_13_PCREL    00000000   foo + 0
                                         ^----- see

and

  readelf -r clang-BareMinimum.o
  
  Relocation section '.rela.text' at offset 0xb8 contains 2 entries:
   Offset     Info    Type            Sym.Value  Sym. Name + Addend
  00000000  00000212 R_AVR_CALL        00000000   bar + 0
  00000004  00000312 R_AVR_CALL        00000000   foo + 0
                                         ^----- see

Is the bug of LLVM's AVR target?
