I think you can do that with the help of `-Xclang > -ast-dump`. Heh, yeah I tried that, and hit an assertion before we were able to dump the full AST. | | | | `-TypedefDecl 0x7f4a5cf03fb0 <line:72:3, line:73:106> col:106 referenced SegmentWrapper 'std::conditional_t<CanAlign, Ref<const Matrix<Scalar, Dynamic, 1, 0, blockSize, 1>, internal::evaluator<VectorTypeCopyClean>::Alignment>, typename VectorTypeCopyClean::ConstSegmentReturnType>':'clang-18: /android0/llvm-project/clang/lib/AST/NestedNameSpecifier.cpp:309: void clang::NestedNameSpecifier::print(raw_ostream &, const PrintingPolicy &, bool) const: Assertion `!isa<ElaboratedType>(T) && "Elaborated type in nested-name-specifier"' failed. 2.75 hours of cvise later: https://github.com/llvm/llvm-project/issues/43179#issuecomment-1719922669 Can probably either rebuild with assertions disabled, or put a clearly wrong type and have the compiler tell me what it was.
