+A C statement (sans semicolon) to output to the stdio stream
+@var{stream} any text necessary for declaring the name @var{name} of a
+constant which is being defined.  This macro is responsible for
+outputting the label definition (perhaps using
+@code{ASM_OUTPUT_LABEL}).  The argument @var{exp} is the
+value of the constant, and @var{size} is the size of the constant
+in bytes.  @var{name} will be an internal label.
+
+If this macro is not defined, then the @var{name} is defined in the
+usual manner as a label (by means of @code{ASM_OUTPUT_LABEL}).
