/// architectures
/// and inline assembly.
/// \details <tt>config.h</tt> was split into components in May 2019 to better
/// integrate with Autoconf and its feature tests. The splitting occurred so
/// users could continue to include <tt>config.h</tt> while allowing Autoconf
/// to write new <tt>config_asm.h</tt> and new <tt>config_cxx.h</tt> using
/// its feature tests.
/// \note You should include <tt>config.h</tt> rather than <tt>config_asm.h</tt>
/// directly.
