Hi!I observed that for a (slowly increasing?) number of C++ testcases (gcc/testsuite/g++.*/), their nvptx compilation fails as follows:
This is occurring because in C++land (some?) functions that return structs via a hidden parameter now also return a reference to that struct (see cp_genericize in cp-gimplify.c). Hence it is possible for RETURN_IN_REG (return_type) to be false AND for a return value in a register (!).
