rnk added a comment. Interesting. In Clang, we basically layer the C++ rules over the C rules: if C++ aspects of a class allow it to be passed directly transparently, then we defer down to the C rules, which deal with HVAs, structs, and things like that.

Can you file an issue for that and cc me? ================ Comment at: clang/test/CodeGenCXX/homogeneous-aggregates.cpp:294 +typedef double V __attribute((ext_vector_type(2))); +struct base { V v; }; +struct test { test(double); protected: V v2;}; ---------------- Can you do the same test again with a non-vector field (double) for test coverage? ================ Comment at: clang/test/CodeGenCXX/homogeneous-aggregates.cpp:295 +struct base { V v; }; +struct test { test(double); protected: V v2;}; +test f(test *x) { return *x; } ---------------- Did you mean to inherit from `base` here to make a two-element HVA?
