- <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.

- <p>The current motivation for parameter attributes is to enable the sign and
- zero extend information necessary for the C calling convention to be passed
- from the front end to LLVM. The <tt>zext</tt> and <tt>sext</tt> attributes
- are used by the code generator to perform the required extension. However,
- parameter attributes are an orthogonal feature to calling conventions and
- may be used for other purposes in the future.</p>
