6/// \brief Library configuration file
7/// \details <tt>config_asm.h</tt> provides defines for instruction set
8/// architectures
9/// and inline assembly.
10/// \details <tt>config.h</tt> was split into components in May 2019 to better
11/// integrate with Autoconf and its feature tests. The splitting occurred so
12/// users could continue to include <tt>config.h</tt> while allowing Autoconf
13/// to write new <tt>config_asm.h</tt> and new <tt>config_cxx.h</tt> using
14/// its feature tests.
15/// \note You should include <tt>config.h</tt> rather than <tt>config_asm.h</tt>
16/// directly.
