------- 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.
