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.  */
