--- Comment #43 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Author: jvdelisle Date: Sat Mar 15 20:31:33 2014 New Revision: 208595 URL: http://gcc.gnu.org/viewcvs?rev=208595&root=gcc&view=rev Log: 2014-03-15 Jerry DeLisle <jvdeli...@gcc.gnu> Backport from mainline PR libfortran/58324 PR libfortran/38199 * io/list_read.c (finish_list_read): Read one character to check for the end of the file. If it is the end, then issue the file end error message. If not, use eat_line to reach the end without giving error. The next attempt to read will then issue the error as described above. * io/read.c (read_decimal): Quickly skip spaces to avoid calls to next_char. * io/unit.c (is_trim_ok): New helper function to check various conditions to see if its OK to trim the internal unit string. (get_internal_unit): Use LEN_TRIM to shorten selected internal unit strings for optimizing READ. Enable this optimization for formatted READ.
