aaron.ballman added a comment. Thank you for working on this!
================ Comment at: clang/docs/ReleaseNotes.rst:59 -------------------- +- Improved `__builtin_offsetof` support, allowing qualified name in member designator. ---------------- You should also link to https://github.com/llvm/llvm-project/issues/64154 here to tie it back to a bug report. ================ Comment at: clang/include/clang/Sema/Sema.h:6038 SourceLocation LocStart, LocEnd; bool isBrackets; // true if [expr], false if .ident + bool isQualifier; ---------------- I think we should combine `isBrackets` and `isQualifier` since a component can't be both at the same time anyway. e.g., ``` enum { Brackets, // U.E is valid Identifier, // U.IdentInfo is valid Qualifier, // Nothing in U is valid } Kind; ``` ================ Comment at: clang/test/Sema/offsetof.c:77-79 +struct X2 { int a; }; +int x2[__builtin_offsetof(struct X2, X2::a) == 0 ? 1 : -1]; +int x3[__builtin_offsetof(struct X2, X2::X2) == 0 ? 1 : -1]; // expected-error{{no member named 'X2'}} ---------------- Neither of these should be valid in C -- there is no way to name subobjects in C like there is in C++. ================ Comment at: clang/test/SemaCXX/offsetof.cpp:104 +struct X2 { int a; static int static_a; }; +int x2[__builtin_offsetof(struct X2, X2::static_a) == 0 ? 1 : -1]; // expected-error{{no member named 'static_a'}} ---------------- It'd be good to add the `int x2[__builtin_offsetof(struct X2, X2::a) == 0 ? 1 : -1];` test here from the C test.
