"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. +

"fastcc" - The fast calling convention:
This calling convention attempts to make calls as fast as possible
