2016-09-23 Jerry DeLisle <jvdelisle@gcc.gnu.org> PR libgfortran/48298 * io/inquire.c (inquire_via_unit): Adjust error check for the two possible internal unit KINDs. * io/io.h: Adjust defines for is_internal_unit and is_char4_unit. (gfc_unit): Add internal unit data to structure. (get_internal_unit): Change declaration to set_internal_unit. (free_internal_unit): Change name to stash_internal_unit_number. (get_unique_unit_number): Adjust parameter argument. Define IOPARM_DT_HAS_UDTIO. (gfc_saved_unit): New structure. * io/list_read.c (next_char_internal): Use is_char4_unit. * io/open.c (st_open): Adjust call to get_unique_unit_number. * io/transfer.c (write_block): Use is_char4_unit. (data_transfer_init): Update check for unit numbers. (st_read_done): Free the various allocated memories used for the internal units and stash the negative unit number and pointer to unit structure to allow reuse. (st_write_done): Likewise stash the freed unit. * io/unit.c: Create a fixed size buffer of 16 gfc_saved_unit's to use as a stack to save newunit unit numbers and unit structure for reuse. (get_external_unit): Change name to get_gfc_unit to better reflect what it does. (find_unit): Change call to get_gfc_unit. (find_or_create_unit): Likewise. (get_internal_unit): Change name to set_internal_unit. Move internal unit from the dtp structure to the gfc_unit structure so that it can be passed to child I/O statements through the UNIT. (free_internal_unit): Change name to stash_internal_unit_number. Push the common.unit number onto the newunit stack, saving it for possible reuse later. (get_unit): Set the internal unit KIND. Use get_unique_unit_number to get a negative unit number for the internal unit. Use get_gfc_unit to get the unit structure and use set_internal_unit to initialize it. (init_units): Initialize the newunit stack. (get_unique_unit_number): Check the stack for an available unit number and use it. If none there get the next most negative number. (close_units): Free any unit structures pointed to from the save stack. 2016-09-23 Jerry DeLisle <jvdelisle@gcc.gnu.org> PR fortran/48298 * gfortran.h (gfc_dt): Add *udtio. * ioparm.def: Add bit IOPARM_dt_f2003 to align with library use of bit 25. Add IOPARM_dt_dtio bit to common flags. * resolve.c (resolve_transfer): Set dt->udtio to expression. * io.c (gfc_match_inquire): Adjust error message for internal unit KIND. * libgfortran.h: Adjust defines for GFC_INTERNAL_UNIT4, GFC_INTERNAL_UNIT, and GFC_INVALID_UNIT. * trans-io.c (build_dt): Set common_unit to reflect the KIND of the internal unit. Set mask bit for presence of dt->udtio. 2016-09-23 Jerry DeLisle <jvdelisle@gcc.gnu.org> PR fortran/48298 * gfortran.dg/negative_unit_check.f90: Update test. * gfortran.dg/dtio_14.f90: New test.
