------- Additional Comments From steven at gcc dot gnu dot org 2005-07-08 14:58 -------
Bug 7561 is apparently a long-forgotten bug in loop.c array prefetching.
Bug 21323 is a stength reduction ICE in loop.c.
Bug 21848 is a report about loop.c producing wrong code.
Bug 22325 is a missed optimization related to "final value replacement" where
the final value is not a constant.
Bug 20376 is a report about missing GIV splitting in the new unroller.
Also note the wiki page, "http://gcc.gnu.org/wiki/old loop optimizer".
