tools/bpf: add test_btf unit tests for kind_flag
This patch added unit tests for different types handling
type->info.kind_flag. The following new tests are added:
$ test_btf
...
BTF raw test[82] (invalid int kind_flag): OK
BTF raw test[83] (invalid ptr kind_flag): OK
BTF raw test[84] (invalid array kind_flag): OK
BTF raw test[85] (invalid enum kind_flag): OK
BTF raw test[86] (valid fwd kind_flag): OK
BTF raw test[87] (invalid typedef kind_flag): OK
BTF raw test[88] (invalid volatile kind_flag): OK
BTF raw test[89] (invalid const kind_flag): OK
BTF raw test[90] (invalid restrict kind_flag): OK
BTF raw test[91] (invalid func kind_flag): OK
BTF raw test[92] (invalid func_proto kind_flag): OK
BTF raw test[93] (valid struct kind_flag, bitfield_size = 0): OK
BTF raw test[94] (valid struct kind_flag, int member, bitfield_size != 0): OK
BTF raw test[95] (valid union kind_flag, int member, bitfield_size != 0): OK
BTF raw test[96] (valid struct kind_flag, enum member, bitfield_size != 0): OK
BTF raw test[97] (valid union kind_flag, enum member, bitfield_size != 0): OK
BTF raw test[98] (valid struct kind_flag, typedef member, bitfield_size != 0): OK
BTF raw test[99] (valid union kind_flag, typedef member, bitfield_size != 0): OK
BTF raw test[100] (invalid struct type, bitfield_size greater than struct size): OK
BTF raw test[101] (invalid struct type, kind_flag bitfield base_type int not regular): OK
BTF raw test[102] (invalid struct type, kind_flag base_type int not regular): OK
BTF raw test[103] (invalid union type, bitfield_size greater than struct size): OK
...
PASS:122 SKIP:0 FAIL:0
The second parameter name of macro
BTF_INFO_ENC(kind, root, vlen)
in selftests test_btf.c is also renamed from "root" to "kind_flag".
Note that before this patch "root" is not used and always 0.
