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.
|

|
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.
|
|
131
|
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.
|
|
111
|
49 TUNE Tune value for the given configuration, otherwise NONE. */
