[Bug rtl-optimization/42511] [4.5 Regression] bootstrap error in stage3 on alpha-linux-gnu

------- Comment #17 from ubizjak at gmail dot com  2010-01-06 18:14 -------
This bug is similar (or even a duplicate of) PR21767. ifcvt.c has a fixup code
for cases like this, grep ifcvt.c for:

      /* PR 21767: When moving insns above a conditional branch, REG_EQUAL
         notes might become invalid.  */

So, let's analyse why this fixup doesn't trigger for attached testcase.
