--- Comment #6 from Doug Gilmore <doug.gilmore at imgtec dot com> --- > It also looks like mips lacks implementation of any of the > vectorizer cost hooks and thus defaults to > default_builtin_vectorization_cost which means that unaligned > loads/stores have double cost. Removing the double cost for unaligned memory OPs didn't have any effect, pealing still occurred and the alias problem is exposed on MIPS. So it looks like we need to come up with fix for bug 69710, that hopefully also fixes bug68030, to address is issue.
