They are known not to be ABI compatible, see e.g. https://bugs.llvm.org/buglist.cgi?quicksearch=42439%2C19909%2C44228%2C12207 That is just one arch, has anyone e.g. tried gcc make check-gcc check-c++-all RUN_ALL_COMPAT_TESTS=1 ALT_CC_UNDER_TEST=clang \ ALT_CXX_UNDER_TEST=clang++ RUNTESTFLAGS=struct-layout-1.exp on different architectures? That might come up with more. Is e.g. C++ struct A {}; struct B { [[no_unique_address]] A a; double b; }; passed by value the same between g++ 10 and latest clang++?
