re PR fortran/40196 ([F03] [F08] Type parameter inquiry (str%len, a%kind) and Complex parts (z%re, z%im))
2018-11-01 Paul Thomas <pault@gcc.gnu.org> PR fortran/40196 * dependency.c (are_identical_variables): Return false if the inquiry refs are not the same. (gfc_ref_needs_temporary_p): Break on an inquiry ref. * dump_parse_tree.c (show_ref): Show the inquiry ref type. * expr.c (gfc_free_ref_list): Break on an inquiry ref. (gfc_copy_ref): Copy the inquiry ref types. (find_inquiry_ref): New function. (simplify_const_ref, simplify_ref_chain): Call it. Add new arg to simplify_ref_chain. (gfc_simplify_expr): Use the new arg in call to simplify_ref_chain. (gfc_get_full_arrayspec_from_expr, gfc_is_coarray): Break on inquiry ref. (gfc_traverse_expr): Return true for inquiry ref. * frontend-passes.c (gfc_expr_walker): Break on inquiry ref. * gfortran.h : Add enums and union member in gfc_ref to implement inquiry refs. * intrinsic.c : Fix white nois. * match.c (gfc_match_assignment): A constant lavlue is an error. * module.c : Add DECL_MIO_NAME for inquiry_type and the mstring for inquiry_types. (mio_ref): Handle inquiry refs. * primary.c (is_inquiry_ref): New function. (gfc_match_varspec): Handle inquiry refs calling new function. (gfc_variable_attr): Detect inquiry ref for disambiguation with components. (caf_variable_attr): Treat inquiry and substring refs in the same way. * resolve.c (find_array_spec): ditto. (gfc_resolve_substring_charlen): If there is neither a charlen ref not an inquiry ref, return. (resolve_ref): Handle inqiry refs as appropriate. (resolve_allocate_expr): Entities with an inquiry ref cannot be allocated. * simplify.c (simplify_bound, simplify_cobound): Punt on inquiry refs. * trans-array.c (get_array_ctor_var_strlen): Break on inquiry ref. *trans-expr.c (conv_inquiry): New function. (gfc_conv_variable): Retain the last typespec to pass to conv_inquiry on detecting an inquiry ref. 2018-11-01 Paul Thomas <pault@gcc.gnu.org> PR fortran/40196 * gfortran.dg/inquiry_part_ref_1.f08: New test. * gfortran.dg/inquiry_part_ref_2.f90: New test. * gfortran.dg/inquiry_part_ref_3.f90: New test.
