--- Comment #17 from Bernhard Reutner-Fischer <aldot at gcc dot gnu.org> ---
Do we want to address arrays always at position 0 (maybe to help graphite ?) or
would it be sufficient to just not dereference the array "before" the first
position like Mikael suggests in comment #14?
gfc_conv_expr_descriptor has this
if (se->data_not_needed)
gfc_conv_descriptor_data_set (&loop.pre, parm,
gfc_index_zero_node);
else
/* Point the data pointer at the 1st element in the section. */
gfc_get_dataptr_offset (&loop.pre, parm, desc, base,
subref_array_target, expr);
gfc_conv_descriptor_offset_set (&loop.pre, parm, offset);
where base is (for "section"-addressing) 9 for the testcase in comment #16 as
can be seen in Richard's initial report.
