--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Probably needs enhancement here:
/* Apply our simple cost model - fuse partitions with similar
memory accesses. */
for (i = 0; partitions.iterate (i, &into); ++i)
{
bool changed = false;
if (partition_builtin_p (into))
continue;
for (int j = i + 1;
partitions.iterate (j, &partition); ++j)
{
if (!partition_builtin_p (partition)
&& similar_memory_accesses (rdg, into, partition))
{
if (dump_file && (dump_flags & TDF_DETAILS))
{
fprintf (dump_file, "fusing partitions\n");
dump_bitmap (dump_file, into->stmts);
see how we do not let detected patterns participate in the cost modeling.
