    * varasm.c (output_constant): Return the number of bytes actually
    emitted.
    (output_constructor_array_range): Update the field size with the
    number of bytes emitted by output_constant.
    (output_constructor_regular_field): Likewise.  Also do not
     complain if the total number of bytes emitted is now greater
    than the expected fieldpos.
    * output.h (output_constant): Update prototype and descriptive
    comment.

    * gcc.c-torture/compile/pr28865.c: New.
    * gcc.c-torture/execute/pr28865.c: New.
