2017-11-13Introduce logical_type_node and use itjb
Backport from trunk. Earlier GFortran used to redefine boolean_type_node, which in the rest of the compiler means the C/C++ _Bool/bool type, to the Fortran default logical type. When this redefinition was removed, a few issues surfaced. Namely, 1) PR 82869, where we created a boolean tmp variable, and passed it to the runtime library as a Fortran logical variable of a different size. 2) Fortran specifies that logical operations should be done with the default logical kind, not in any other kind. 3) Using 8-bit variables have some issues, such as - on x86, partial register stalls and length prefix changes. - s390 has a compare with immediate and jump instruction which works with 32-bit but not 8-bit quantities. This patch addresses these issues by introducing a type logical_type_node which is a Fortran LOGICAL variable of default kind. It is then used in places were the Fortran standard mandates, as well as for compiler generated temporary variables. For x86-64, using the Polyhedron benchmark suite, no performance or code size difference worth mentioning was observed.

2017-01-13PR 78534 Change character length from int to size_tjb
In order to handle large character lengths on (L)LP64 targets, switch the GFortran character length from an int to a size_t. This is an ABI change, as procedures with character arguments take hidden arguments with the character length. I also changed the _size member in vtables from int to size_t, as there were some cases where character lengths and sizes were apparently mixed up and caused regressions otherwise. Although I haven't tested, this might enable very large derived types as well. Also, as there are some places in the frontend were negative character lengths are used as special flag values, in the frontend the character length is handled as a signed variable of the same size as a size_t, although in the runtime library it really is size_t. I haven't changed the character length variables for the co-array intrinsics, as this is something that may need to be synchronized with OpenCoarrays. This is v4 of the patch. v3 was applied but had to reverted due to breaking bootstrap. The fix is in resolve.c:resolve_charlen, where it's necessary to check that an expression is constant before using mpz_sgn. Overview of v3 of the patch: All the issues pointed out by FX's review of v2 have been fixed. In particular, there are now new functions gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT instead of a long value. Similarly, gfc_get_int_expr now takes a HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by gfc_extract_hwi. Also, the preliminary work to handle gfc_charlen_type_node being unsigned has been removed.

2017-01-03PR 78534 Change character length from int to size_tjb
In order to handle large character lengths on (L)LP64 targets, switch the GFortran character length from an int to a size_t. This is an ABI change, as procedures with character arguments take hidden arguments with the character length. I also changed the _size member in vtables from int to size_t, as there were some cases where character lengths and sizes were apparently mixed up and caused regressions otherwise. Although I haven't tested, this might enable very large derived types as well. Also, as there are some places in the frontend were negative character lengths are used as special flag values, in the frontend the character length is handled as a signed variable of the same size as a size_t, although in the runtime library it really is size_t. I haven't changed the character length variables for the co-array intrinsics, as this is something that may need to be synchronized with OpenCoarrays. This is v3 of the patch. All the issues pointed out by FX's review of v2 have been fixed. In particular, there are now new functions gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT instead of a long value. Similarly, gfc_get_int_expr now takes a HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by gfc_extract_hwi. Also, the preliminary work to handle gfc_charlen_type_node being unsigned has been removed.

Add INTERFACE_DTIO to interface type. Add new enum 'dtio_codes'. Add bitfield 'has_dtio_procs' to symbol_attr. Add prototypes 'gfc_check_dtio_interfaces' and 'gfc_find_specific_dtio_proc'. * interface.c (dtio_op): New function. (gfc_match_generic_spec): Match generic DTIO interfaces. (gfc_match_interface): Treat DTIO interfaces in the same way as (gfc_current_interface_head): Add INTERFACE_DTIO appropriately. (check_dtio_arg_TKR_intent): New function. (check_dtio_interface1): New function. (gfc_check_dtio_interfaces): New function. (gfc_find_specific_dtio_proc): New function. * io.c : Add FMT_DT to format_token. (format_lex): Handle DTIO formatting. * match.c (gfc_op2string): Add DTIO operators. * resolve.c (derived_inaccessible): Ignore pointer components to enclosing derived type. (resolve_transfer): Resolve transfers that involve DTIO. procedures. Find the specific subroutine for the transfer and use its existence to over-ride some of the constraints on derived types. If the transfer is recursive, require that the subroutine be so qualified. (dtio_procs_present): New function. (resolve_fl_namelist): Remove inhibition of polymorphic objects in namelists if DTIO read and write subroutines exist. Likewise for derived types. (resolve_types): Invoke 'gfc_verify_dtio_procedures'. * symbol.c : Set 'dtio_procs' using 'minit'. * trans-decl.c (gfc_finish_var_decl): If a derived-type/class object is associated with DTIO procedures, make it TREE_STATIC. * trans-expr.c (gfc_get_vptr_from_expr): If the expression drills down to a PARM_DECL, extract the vptr correctly. (gfc_conv_derived_to_class): Check 'info' in the test for 'useflags'. If the se expression exists and is a pointer, use it as the class _data. * trans-io.c : Add IOCALL_X_DERIVED to iocall and the function prototype. Likewise for IOCALL_SET_NML_DTIO_VAL. (set_parameter_tree): Renamed from 'set_parameter_const', now returns void and has new tree argument. Calls modified to match new interface. (transfer_namelist_element): Transfer DTIO procedure pointer and vpointer using the new function IOCALL_SET_NML_DTIO_VAL. (get_dtio_proc): New function. (transfer_expr): Add new argument for the vptr field of class objects. Add the code to call the specific DTIO proc, convert derived types to class and call IOCALL_X_DERIVED. (trans_transfer): Add BT_CLASS to structures for treatment by the scalarizer. Obtain the vptr for the dynamic type, both for scalar and array transfer. 2016-08-31 Jerry DeLisle <jvdelisle@gcc.gnu.org> Paul Thomas <pault@gcc.gnu.org> PR libgfortran/48298 * gfortran.map : Flag _st_set_nml_dtio_var and _gfortran_transfer_derived. * io/format.c (format_lex): Detect DTIO formatting. (parse_format_list): Parse the DTIO format. (next_format): Include FMT_DT. * io/format.h : Likewise. Add structure 'udf' to structure 'fnode' to carry the IOTYPE string and the 'vlist'. * io/io.h : Add prototypes for the two types of DTIO subroutine and a typedef for gfc_class. Also, add to 'namelist_type' fields for the pointer to the DTIO procedure and the vtable. Add fields to struct st_parameter_dt for pointers to the two types of DTIO subroutine. Add to gfc_unit DTIO specific fields. (internal_proto): Add prototype for 'read_user_defined' and 'write_user_defined'. * io/list_read.c (check_buffers): Use the 'current_unit' field. (unget_char): Likewise. (eat_spaces): Likewise. (list_formatted_read_scalar): For case BT_CLASS, call the DTIO procedure.

Add extra arguments for st_set_nml_var prototype. (set_nml_var): New function that contains the contents of the old version of st_set_nml_var. Also sets the 'dtio_sub' and 'vtable' fields of the 'nml' structure. (st_set_nml_var): Now just calls set_nml_var with 'dtio_sub' and 'vtable' NULL. (st_set_nml_dtio_var): New function that calls set_nml_var. * io/unit.c (get_external_unit): If the found unit child_dtio is non zero, don't do any mutex locking/unlocking. Just return the unit. * io/unix.c (tempfile_open): Revert to C style comment. * io/write.c (list_formatted_write_scalar): Do the DTIO call. (nml_write_obj): Add BT_CLASS and do the DTIO call. 2016-08-31 Jerry DeLisle <jvdelisle@gcc.gnu.org> Paul Thomas <pault@gcc.gnu.org> PR fortran/48298 * gfortran.dg/dtio_1.f90: New test. * gfortran.dg/dtio_2.f90: New test. * gfortran.dg/dtio_3.f90: New test. * gfortran.dg/dtio_4.f90: New test. * gfortran.dg/dtio_5.f90: New test. * gfortran.dg/dtio_6.f90: New test. * gfortran.dg/dtio_7.f90: New test. * gfortran.dg/dtio_8.f90: New test. * gfortran.dg/dtio_9.f90: New test. * gfortran.dg/dtio_10.f90: New test. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@239880 138bc75d-0d04-0410-961f-82ee72b054a4
