  20 /* List of various ARC CPU configurations.  If updated, cd to
  21    $(builddir)/gcc and run
  22
  23    $ make arc-cpus
  24
  25    This will regenerate / update the following source files:
  26
  27    -  $(srcdir)/config/arc/t-multilib
  28    -  $(srcdir)/config/arc/arc-tables.opt
  29
  30    After that, rebuild everything and check-in the new sources to the
  31    repo.  This file defines the accepted values for -mcpu=<CPU>
  32    option.
  33
  34    Before including this file, define a macro:
  35
  36    ARC_CPU (NAME, ARCH, FLAGS, TUNE)
  37
  38    where the arguments are the fields of arc_cpu_t:
  39
  40    NAME   A given arbitrary name.
  41    ARCH   Base architecture for the given CPU.
  42    FLAGS  Specific hardware flags that are enabled by this CPU configuration,
  43           as defined in arc-options.def file, and allowed by arc-arches.def
  44           file.  The specific hardware flags are enumerated without using
  45           spaces between the '|' character and consequtive flags.
  46    EXTRA  Extra hardware flags, different than the ones in
  47           arc-arches.def.  Here we can specify the width of lp_count,
  48           for example.
  49    TUNE   Tune value for the given configuration, otherwise NONE.  */
