2016-06-23 Jerry DeLisle <jvdelisle@gcc.gnu.org> PR libgfortran/48852 * io/write.c: Cleaned up whitespace. (write_d, write_e, write_f, write_es, write_en): Use new helper function write_float_0. (write_float_0): New helper function. (get_precision, select_buffer, select_string, write_float_string): New helper functions used in remaining float writing functions. Helper function write_float_string now contains code for writing to kind=4 character internal units. (write_real): Modified to establish working buffers at this level and to use new helper functions. (write_real_g0): Likewise modified. (write_complex): Likewise modified. Gets both float strings before output so that final lengths can be determined which allows right justifying the complex number with no intervening spaces. * io/write_float.def (build_float_string): Renamed from previosly output_float, modified to use buffers passed in from higher functions, builds a null terminated string of the floating point value. Character kind=4 code eliminated. (write_infnan): Likewise modified to use incoming buffers and eliminate kind=4 related code. (OUTPUT_FLOAT_FMT_G): Deleted, functionality moved into FORMAT_FLOAT. (FORMAT_FLOAT): Renamed macro from WRITE_FLOAT. Use build_float_string. (get_float_string): Renamed from write_float, uses FORMAT_FLOAT macro. Buffer allocation removed, now at higher level. PR libgfortran/48852 * gfortran.dg/char4_iunit_1.f03: Update test. * gfortran.dg/f2003_io_5.f03: Update test. * gfortran.dg/real_const_3.f90: Update test. From-SVN: r237735

nml_write_obj writes a namelist object to the output stream. It is called

recursively for derived type components:
|
|
obj = is the namelist_info for the current object.
|
|
offset = the offset relative to the address held by the object for
|
|
derived type arrays.
|
|
base = is the namelist_info of the derived type, when obj is a
|
|
component.
|
|
base_name = the full name for a derived type, including qualifiers
|
|
if any.
|
|
The returned value is a pointer to the object beyond the last one
|
|
accessed, including nested derived types. Notice that the namelist is
|
|
a linear linked list of objects, including derived types and their
|
|
components. A tree, of sorts, is implied by the compound names of
|
|
the derived type components and this is how this function recurses through
|
|
the list. */
