--- Comment #1 from jcmvbkbc at gcc dot gnu.org --- The issue does not reproduce with the current gcc trunk after SVN revision 277054 (generalized IPA predicate on parameter), but it doesn't look like this change fixes the root cause, it just results in inlining of bitmap_replace() into the test_replace().
