[Bug rtl-optimization/26449] [4.2/4.3 Regression] ICE in loop invariant motion



------- Comment #10 from ubizjak at gmail dot com  2007-06-01 06:39 -------
Not fixed, please look for the same failure at PR32123.

          start_sequence ();
          op = force_operand (SET_SRC (set), reg);
+         if (!op)
+           {
+             end_sequence ();
+             goto fail;
+           }
          if (op != reg)

Also, this fix is wrong, force opereand will not return NULL, but will ICE if
value can't be expanded via optab.
