[Daniel Bertalan via Phabricator via cfe-commits]

BertalanD added a comment.

I tried out D135772 <https://reviews.llvm.org/D135772>, and our build got 
significantly farther than before! I unfortunately discovered another piece of 
code that pre babdef27c503c0bbbcc017e9f88affddda90ea4e 
<https://reviews.llvm.org/rGbabdef27c503c0bbbcc017e9f88affddda90ea4e> Clang and 
GCC accept in C++20 mode, but Clang trunk does not 
(https://godbolt.org/z/q1q4nfobK):

  struct String {
    String(char *);
    bool operator==(String const &);
    void operator!=(String const &);
  };
  
  extern char* c;
  extern String s;
  int test() {
    return c == s;
  }



  <source>:10:12: error: invalid operands to binary expression ('char *' and 
'String')
    return c == s;
