Commit for Asher Langton
PR fortran/17031 PR fortran/22282 fortran/ * check.c (gfc_check_loc) : New function * decl.c (variable_decl): New variables cp_as and sym. Added a check for variables that have already been declared as Cray Pointers, so we can get the necessary attributes without adding a new symbol. (attr_decl1): Added code to catch pointee symbols and "fix" their array specs. (cray_pointer_decl): New method. (gfc_match_pointer): Added Cray pointer parsing code. (gfc_mod_pointee_as): New method. * expr.c (gfc_check_assign): added a check to catch vector-type assignments to pointees with an unspecified final dimension. * gfortran.h: (GFC_ISYM_LOC): New. (symbol_attribute): Added cray_pointer and cray_pointee bits. (gfc_array_spec): Added cray_pointee and cp_was_assumed bools. (gfc_symbol): Added gfc_symbol *cp_pointer. (gfc_option): Added flag_cray_pointer. (gfc_add_cray_pointee): Declare. (gfc_add_cray_pointer ): Declare. (gfc_mod_pointee_as): Declare. * intrinsic.c (add_functions): Add code for loc() intrinsic. * intrinsic.h (gfc_check_loc): Declare. (gfc_resolve_loc): Declare. * iresolve.c (gfc_resolve_loc): New. * lang.opt: Added fcray-pointer flag. * options.c (gfc_init_options): Intialized gfc_match_option.flag_cray_pointer. (gfc_handle_option): Deal with -fcray-pointer. * parse.c:(resolve_equivalence): Added code prohibiting Cray pointees in equivalence statements. * resolve.c (resolve_array_ref): Added code to prevent bounds checking for Cray Pointee arrays. (resolve_equivalence): Prohibited pointees in equivalence statements. * symbol.c (check_conflict): Added Cray pointer/pointee attribute checking. (gfc_add_cray_pointer): New (gfc_add_cray_pointee): New (gfc_copy_attr): New code for Cray pointers and pointees * trans-array.c (gfc_trans_auto_array_allocation): Added code to prevent space from being allocated for pointees. (gfc_conv_array_parameter): Added code to catch pointees and correctly set their base address. * trans-decl.c (gfc_finish_var_decl): Added code to prevent pointee declarations from making it to the back end. (gfc_create_module_variable): Same. * trans-expr.c (gfc_conv_variable): added code to detect and translate pointees. (gfc_conv_cray_pointee): New. * trans-intrinsic.c (gfc_conv_intrinsic_loc): New. (gfc_conv_intrinsic_function): added entry point for loc translation. * trans.h (gfc_conv_cray_pointee): Declare. * gfortran.texi: Added section on Cray pointers, removed Cray pointers from list of proposed extensions * intrinsic.texi: Added documentation for loc intrinsic. * invoke.texi: Documented -fcray-pointer flag testsuite/ PR fortran/17031 PR fortran/22282 * gfortran.dg/cray_pointers_1.f90: New test. * gfortran.dg/cray_pointers_2.f90: New test. * gfortran.dg/cray_pointers_3.f90: New test. * gfortran.dg/loc_1.f90: New test. * gfortran.dg/loc_2.f90: New test.
