Possible typo in LRA

[sa...@hederstierna.com]

Hi

When reviewing some code from LRA, I just saw some lines that looked a bit 
strange,
could it be a possible typo perhaps?

The file "lra.c" from GC5 master branch current date

Line 469:

              /* Try x = index_scale; x = x + disp; x = x + base.  */
              last = get_last_insn ();
              rtx_insn *move_insn = emit_move_insn (x, index_scale);
              ok_p = false;
              if (recog_memoized (move_insn) >= 0)
                {
                  rtx insn = emit_add2_insn (x, disp);
                  if (insn != NULL_RTX)
                    {
                      insn = emit_add2_insn (x, disp);
                      if (insn != NULL_RTX)
                        ok_p = true;
                    }
                }

Shouldn't the code be as the comment suggest to in the second call to 
emit_add2_insn use 'base' ?

-                     insn = emit_add2_insn (x, disp);
+                     insn = emit_add2_insn (x, base);

Maybe the code is right, I tried to mail vmakarov, some months ago, but did not 
get any reply.
But it looks like I typo, so I just wanted to verify it so its not a bug,

Thanks and Kind Regards, Fredrik
