+/* List of various ARC CPU configurations.  If updated, cd to
+   $(builddir)/gcc and run
+
+   $ make arc-cpus
+
+   This will regenerate / update the following source files:
+
+   -  $(srcdir)/config/arc/t-multilib
+   -  $(srcdir)/config/arc/arc-tables.opt
+
+   After that, rebuild everything and check-in the new sources to the
+   repo.  This file defines the accepted values for -mcpu=<CPU>
+   option.
+
+   Before including this file, define a macro:
+
+   ARC_CPU (NAME, ARCH, FLAGS, TUNE)
+
+   where the arguments are the fields of arc_cpu_t:
+
+   NAME	  A given arbitrary name.
+   ARCH	  Base architecture for the given CPU.
+   FLAGS  Specific hardware flags that are enabled by this CPU configuration,
+	  as defined in arc-options.def file, and allowed by arc-arches.def
+	  file.  The specific hardware flags are enumerated without using
+	  spaces between the '|' character and consequtive flags.
+   TUNE	  Tune value for the given configuration, otherwise NONE.  */
