<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.
