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. | |
09d69286 CZ |
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. | |
f9ccf899 CZ |
49 | TUNE Tune value for the given configuration, otherwise NONE. */ |
