[Bug rtl-optimization/43742] [4.6 Regression] web.c/union_match_dups segfaults for a null *ref on sh-elf

------- Comment #2 from steven at gcc dot gnu dot org  2010-04-13 06:59 -------
The patch of comment #1 is not the right thing to do. What it means, is that
recog_data finds an operand for which the insn has no df_ref.
