-- sdata.c --
extern char *name;
main()
{
        printf("%s\n",name);
}

 m32r-elf-gcc -c -msdata=use -O0 sdata.c

sdata.c: In function `main':
sdata.c:5: error: unrecognizable insn:
(insn 8 21 9 0 (set (reg:SI 27)
        (unspec [
                (const_int 0 [0x0])
            ] 2)) -1 (nil)
    (nil))
sdata.c:5: internal compiler error: in extract_insn, at recog.c:2083
Comment 1 Andrew Pinski 2004-08-19 06:25:40 UTC 
The insn looks right at least one the mainline and the 3.4 branch:
(define_insn "*load_sda_base"
  [(set (match_operand:SI 0 "register_operand" "=r")
        (unspec:SI [(const_int 0)] UNSPEC_LOAD_SDA_BASE))]
  ""
  "ld24 %0,#_SDA_BASE_"
  [(set_attr "type" "int4")
   (set_attr "length" "4")])

I think so. But It has happened.
