-Define this macro if references to a symbol must be treated differently
-depending on something about the variable or function named by the

-The macro definition, if any, is executed immediately after the rtl for

+Define this macro if references to a symbol or a constant must be

+function named by the symbol (such as what section it is in).
+
+The macro definition, if any, is executed under two circumstances. One
+is immediately after the rtl for @var{decl} that represents a variable
+or a function has been created and stored in @code{DECL_RTL
+(@var{decl})}. The value of the rtl will be a @code{mem} whose address
+is a @code{symbol_ref}. The other is immediately after the rtl for
+@var{decl} that represents a constant has been created and stored in
+@code{TREE_CST_RTL (@var{decl})}. The macro is called once for each
+distinct constant in a source file.
