PR fortran/19239 * Makefile.in (fortran/trans-expr.o): Depend on dependency.h. * dependency.h (gfc_ref_needs_temporary_p): Declare. * dependency.c (gfc_ref_needs_temporary_p): New function. (gfc_check_fncall_dependency): Use it instead of inlined check. By so doing, take advantage of the fact that character substrings within an array reference also need a temporary. * trans.h (GFC_SS_VECTOR): Adjust comment. * trans-array.c (gfc_free_ss): Remove GFC_SS_VECTOR case. (gfc_set_vector_loop_bounds): New function. (gfc_add_loop_ss_code): Call it after evaluating the subscripts of a GFC_SS_SECTION. Deal with the GFC_SS_VECTOR case by evaluating the vector expression and caching its descriptor for use within the loop. (gfc_conv_array_index_ref, gfc_conv_vector_array_index): Delete. (gfc_conv_array_index_offset): Handle scalar, vector and range dimensions as separate cases of a switch statement. In the vector case, use the loop variable to calculate a vector index and use the referenced element as the dimension's index. Perform bounds checking on this final index. (gfc_conv_section_upper_bound): Return null for vector indexes. (gfc_conv_section_startstride): Give vector indexes a start value of 0 and a stride of 1. (gfc_conv_ss_startstride): Adjust for new GFC_SS_VECTOR representation. (gfc_conv_expr_descriptor): Expand comments. Generalize the handling of the !want_pointer && !direct_byref case. Use gfc_ref_needs_temporary_p to decide whether the variable case needs a temporary. (gfc_walk_variable_expr): Handle DIMEN_VECTOR by creating a GFC_SS_VECTOR index. * trans-expr.c: Include dependency.h. (gfc_trans_arrayfunc_assign): Fail if the target needs a temporary. 2005-09-09 Richard Sandiford <richard@codesourcery.com> PR fortran/21104 * trans.h (gfc_interface_sym_mapping, gfc_interface_mapping): Moved from trans-expr.c. (gfc_init_interface_mapping, gfc_free_interface_mapping) (gfc_add_interface_mapping, gfc_finish_interface_mapping) (gfc_apply_interface_mapping): Declare. * trans-array.h (gfc_set_loop_bounds_from_array_spec): Declare. (gfc_trans_allocate_temp_array): Add pre and post block arguments. * trans-array.c (gfc_set_loop_bounds_from_array_spec): New function. (gfc_trans_allocate_array_storage): Replace loop argument with separate pre and post blocks. (gfc_trans_allocate_temp_array): Add pre and post block arguments. Update call to gfc_trans_allocate_array_storage. (gfc_trans_array_constructor, gfc_conv_loop_setup): Adjust for new interface to gfc_trans_allocate_temp_array. * trans-expr.c (gfc_interface_sym_mapping, gfc_interface_mapping): Moved to trans.h. (gfc_init_interface_mapping, gfc_free_interface_mapping) (gfc_add_interface_mapping, gfc_finish_interface_mapping) (gfc_apply_interface_mapping): Make extern. (gfc_conv_function_call): Build an interface mapping for array return values too. Call gfc_set_loop_bounds_from_array_spec. Adjust call to gfc_trans_allocate_temp_array so that code is added to SE rather than LOOP. From-SVN: r104077
