re PR libfortran/90374 (Fortran 2018: Support d0.d, e0.d, es0.d, en0.d, g0.d and ew.d e0 edit descriptors for output)
2019-11-06 Jerry DeLisle <jvdelisle@gcc.ngu.org> PR fortran/90374 * io.c (check_format): Allow zero width for D, E, EN, and ES specifiers as default and when -std=F2018 is given. Retain existing errors when using the -fdec family of flags. * libgfortran/io/format.c (parse_format_list): Relax format checking for zero width as default and when -std=f2018. io/format.h (format_token): Move definition to io.h. io/io.h (format_token): Add definition here to allow access to this definition at higher levels. Rename the declaration of write_real_g0 to write_real_w0 and add a new format_token argument, allowing higher level functions to pass in the token for handling of g0 vs the other zero width specifiers. io/transfer.c (formatted_transfer_scalar_write): Add checks for zero width and call write_real_w0 to handle it. io/write.c (write_real_g0): Remove. (write_real_w0): Add new, same as previous write_real_g0 except check format token to handle the g0 case. * gfortran.dg/fmt_error_10.f: Modify for new constraints. * gfortran.dg/fmt_error_7.f: Add dg-options "-std=f95". * gfortran.dg/fmt_error_9.f: Modify for new constraints. * gfortran.dg/fmt_zero_width.f90: New test.
