Hi All ,
We are porting GCC 4.8.1 for the customized hardware, where the current calling convention used as arguments are passed by stack and return value by register. But we do have some intrinsic functions(that are supplied by hardware folks ) which has the calling convention like both arguments and return value are passed by stack. So question is that currently the backend using usually conventions like arguments are passed by stack ad return value by register ,But how do we can model that only intrinsic uses the caller stack space for return value over registers. Appreciate any hints or shed some lights on the same. Thank you ~Umesh
