Hello, I’m trying to improve SILNode memory layout density by adopting the AST bitfield macros. Unfortunately, multiple inheritance doesn’t seem to get along with anonymous/unnamed unions. Here is a distillation of the problem:
class B { protected: int i; union { int j; }; }; class X : public B { }; class Y : public B { }; class Z : public X, public Y { int a() { return X::i; } // works int b() { return X::j; } // fails }; Is this expected C++ behavior? I can certainly workaround this by naming the unnamed union, but before I do, I thought that I should check here first. Thanks, Dave _______________________________________________ swift-dev mailing list swift-dev@swift.org https://lists.swift.org/mailman/listinfo/swift-dev
