--- Comment #5 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Author: jvdelisle Date: Thu Jan 2 00:57:31 2020 New Revision: 279828 URL: https://gcc.gnu.org/viewcvs?rev=279828&root=gcc&view=rev Log: PR 90374 d0.d, e0.d, es0.d, en0.d, g0.d and ew.d edit descriptors. PR libfortran/90274 * io/format.c (parse_format_list): Implement the E0 exponent width to provide smallest possible width for exponent fields. Refactor code for correct parsing and better readability of the code. * io/io.h (write_real_w0): Change interface to pass in pointer to fnode. * io/transfer.c: Update all calls to write_real_w0 to use the new interface. * io/write.c ((write_real_w0): Use the new interface with fnode to access both the decimal precision and exponent widths used in build_float_string. * io/write_float.def (build_float_string): Use the passed in exponent width to calculate the used width in the case of E0.
