That should of course be 20050323 (not 20030323).

This regression affects ia64-linux which is a secondary platform.

Binary search on ia64-hpux shows the failure appeared between 2005-03-22 22:04
UTC and 2005-03-22 22:30 UTC. The only plausibly responsible patch in that range is
2005-03-22 Zdenek Dvorak <dvorakz@suse.cz>
* tree-ssa-loop-ivopts.c (determine_iv_cost): Do not try to preserve
artificial original candidates.

Hmm, maybe we are just selecting the orignal IV as the IV which we should use, this is just a missed
optimization.

Or it might be the testcase which is matching it wrong, someone already asked about this testcase
before on IRC (IIRC) and the regex was just matching wrongly.

No, that's bug 21341 (if indeed the problem was the regex, the submitter
of the patch which changed the regex didn't mention the bug and its prior
change from PASS to FAIL). There are multiple test assertions within the
same test file, and when any one changes from PASS to FAIL that is in
principle, and in practice in this case, a separate bug.
