[Bug rtl-optimization/32372] [4.3 Regression] ICE in df_refs_verify, at df-scan.c:4065

------- Comment #1 from zadeck at naturalbridge dot com  2007-06-18 12:33 -------
I believe that the failure is due to a an insn illegally sharing with a
reg_equal note.  Insn 8 is modified in regmove.  When this happens, the
reg_equal note in insn 22 magically changes.  That reg_equal note was changed
last in cse.
