Subject: RTTI names for classes in anonymous namespaces
Date: Wed, 23 Aug 2023 14:10:50 +0530	[thread overview]
Message-ID: <> (raw)

[-- Attachment #1: Type: text/plain, Size: 1096 bytes --]

 hello all,

      The RTTI names generated by gcc for classes in anonymous namespaces
begin with the prefix asterisk(*).
      Once the __name pointer is different why do we not return
immediately? Instead we perform a string comparison if the name does not
begin with asterisk(*).
      Could you please explain the reasoning behind this.

      code snippet below:

   type_info::operator==(const type_info& __arg) const _GLIBCXX_NOEXCEPT
      if (std::__is_constant_evaluated())
         return this == &__arg;

      if (__name == __arg.__name)
         return true;

         // ABI requires comparisons to be non-inline.
         return __equal(__arg);
         // Need to do string comparison.
         return __name[0] != '*' && __builtin_strcmp (__name,
== 0;
         return false;
