+ "csretcc" - The C struct return calling convention:
+
+ 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.
