2012-01-27 Paul Thomas <pa...@gcc.gnu.org> Tobias Burnus <bur...@gcc.gnu.org> PR fortran/48705 PR fortran/51870 PR fortran/51943 PR fortran/51946 * trans-array.c (gfc_array_init_size): Add two extra arguments to convey the dynamic element size of a calls object and to return the number of elements that have been allocated. (gfc_array_allocate): Add the same arguments and use them to call gfc_array_init_size. Before the allocation dereference the data pointer, if necessary. Set the allocated array to zero if the class element size or expr3 are non-null. * trans-expr.c (gfc_conv_class_to_class): Give this function global scope. (get_class_array_ref): New function. (gfc_copy_class_to_class): New function. * trans-array.h : Update prototype for gfc_array_allocate. * trans-stmt.c (gfc_trans_allocate): For non-variable class STATUS expressions extract the class object and the dynamic element size. Use the latter to call gfc_array_allocate and the former for setting the vptr and, via gfc_copy_class_to_clasfc_cs, to copy to the allocated data. * trans.h : Prototypes for gfc_get_class_array_ref, gfc_copy_class_to_class and gfc_conv_class_to_class. 2012-01-27 Paul Thomas <pa...@gcc.gnu.org> Tobias Burnus <bur...@gcc.gnu.org> PR fortran/48705 * gfortran.dg/class_allocate_11.f03: New.
