It is much easier for understanding. Thank you! I've tried to consider
an older version.
Is this necessary? The id should already be set in
(graphite-sese-to-poly.c):
static isl_id *
isl_id_for_pbb (scop_p s, poly_bb_p pbb)
{
char name[50];
snprintf (name, sizeof (name), "S_%d", pbb_index (pbb));
return isl_id_alloc (s->ctx, name, pbb);
}
Thank you! I haven't known about this function. Should its declaration
be moved to graphite-sese-to-poly.h or it is better to redefine it in
the graphite-isl-ast-to-gimple.c?
No, nothing of the both. To my understanding the isl_ids you get should
already contain a user pointer to a pbb, which is created at the time
isl_id_for_pbb is called in sese-to-polly. You should be able to just
retrieve it. If that does not work, we should figure out why.
