[PATCH ARC 3/8] GAS: new ARC port

[Nick Clifton]

Hi Claudiu,

I get some compile time errors building with this patch:

   gas/frags.c: In function 'frag_align_code':
   gas/frags.c:377:8: error: overflow in implicit constant conversion 
[-Werror=overflow]
    *p = NOP_OPCODE;

Which makes sense since p is a char* pointer and NOP_OPCODE is 0x000078E0.

   gas/config/tc-arc.c: In function 'md_assemble':
   gas/config/tc-arc.c:2732:17: error: 'reloc' may be used uninitialized 
in this function [-Werror=maybe-uninitialized]
     fixup->reloc = reloc;
                  ^
   gas/config/tc-arc.c:2576:37: note: 'reloc' was declared here
    extended_bfd_reloc_code_real_type reloc;
                                      ^
   gas/config/tc-arc.c:2434:14: error: 't' may be used uninitialized in 
this function [-Werror=maybe-uninitialized]
          || (t->X_add_number != tok[tokidx].X_add_number))
               ^
   gas/config/tc-arc.c:2225:26: note: 't' was declared here
        const expressionS *t;
                           ^

This is with gcc 5 running on Fedora 22...

Cheers
