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.
