Hi,
The attached patch is a stab at adding the necessary compiler builtin to
support std::is_virtual_base_of (P2985R0, approved for C++26). The name
of the builtin matches the one just merged into clang:
https://github.com/llvm/llvm-project/issues/98310
The next patch will add the libstdc++ bits.
Hello,
This is a new revision of the same patch, this time with a DCO.
+ ba_require_virtual = 1 << 3 /* Require a virtual base */
Why change lookup rather than just call lookup_base and then
binfo_from_vbase in trait_expr_value?
