’s post is a list of reserved C++ keywords — words the compiler treats specially, so you can’t use them as ordinary identifiers. This is a language keyword list, not assembly (assembly uses mnemonics like MOV/ADD and very different syntax). For the authoritative, version-annotated list see cppreference.
C++ keywords — cppreference. (en.cppreference.com)

The snapshot posted in 2012 looks like an early-C++11-era list. The language has evolved since then: later standards (notably C++20 and C++23) introduced additional reserved or context-only tokens — for example modules/import, concepts/requires, coroutines (co_await/co_return/co_yield), the char8_t type, and specifiers such as consteval/constinit. cppreference’s keyword page and the per-feature pages show which standard added each token.
C++ keywords — cppreference · char8_t · Concepts / requires. (en.cppreference.com)

Practical advice to avoid surprises: do not choose identifiers that the standard reserves (avoid names with double underscores or a leading underscore followed by a capital letter), and gate code that needs newer language features with feature-test macros or by checking __cplusplus. Example pattern:

#if defined(__cpp_concepts) && __cpp_concepts >= 201907L
  // use concepts
#endif

#if defined(__cpp_char8_t) && __cpp_char8_t >= 201811L
  using u8 = char8_t;
#else
  using u8 = char;
#endif

#if __cplusplus >= 202002L
  // C++20+ specific code
#endif

See cppreference’s feature-test macros and predefined-macro documentation for the macro names and values, and the identifiers page for naming rules.

that isn't c++, it's assembly
