+  <dt><b>"<tt>csretcc</tt>" - The C struct return calling convention</b>:</dt>
+
+  <dd>This calling convention matches the target C calling conventions, except
+  that functions with this convention are required to take a pointer as their
+  first argument, and the return type of the function must be void.  This is
+  used for C functions that return aggregates by-value.  In this case, the
+  function has been transformed to take a pointer to the struct as the first
+  argument to the function.  For targets where the ABI specifies specific
+  behavior for structure-return calls, the calling convention can be used to
+  distinguish between struct return functions and other functions that take a
+  pointer to a struct as the first argument.
