------- Comment #28 from hubicka at gcc dot gnu dot org 2009-03-29 18:26 -------
The testcase is now failing on mainline. Reason seems to be new pure-const
pass causing PRE to take unacceptable amount of time producing extraordinarily
large bitmaps. I stoppped it after while and out of 1GB of memory use, 700MB
was PRE bitmap.
