--- Comment #77 from Mikael Morin <mikael at gcc dot gnu.org> 2012-08-01 12:37:45 UTC --- (In reply to comment #75) > Created attachment 27919 [details] > rough patch > About the patch: The failures are mostly(all?) due to structure constructors. Structure constructors use components' backend_decl which are of restricted types. however, if the lhs is a target, one should use the non-restricted components. I tried fixing the constructor using gfc_convert (see the patch). However, it doesn't work with scalarization, as the constructor is evaluated outside the loop into a variable (which gets the restricted type). So, this patch adds a flag restricted to gfc_conv_structure. the flag propagates to gfc_conv_expr, and gfc_conv_initializer, gfc_conv_initializer, etc. To know whether we need to call gfc_conv_expr with the restricted flag set or not in the scalarizer, a new flag field is added to the scalarizer's gfc_ss_info structures to tell whether we want a non-restricted expression. For it to be set appropriately, a flag is propagated to the gfc_walk_* functions.
