[PATCH] D105439: [clang] protects users from relying on libc++ detail headers

[Christopher Di Bella via Phabricator via cfe-commits]

cjdb added a comment.

I tried the following, but it doesn't work with modules, so it looks like a compiler solution is necessary.

  // in <algorithm>
  #define _LIBCPP_PRIVATE_HEADER_ALLOWED
  
  // in <__algorithm/find.h>
  #ifndef _LIBCPP_PRIVATE_HEADER_ALLOWED
  #error This is a libc++ detail header. Please instead include <algorithm>.
  #endif
