From cc15a20d5f3abc3cbd7911b70156b7b9e2bc7d41 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sat, 11 Jul 2020 23:53:29 +0200 Subject: selftests/bpf: Add test for resolve_btfids Adding resolve_btfids test under test_progs suite. It's possible to use btf_ids.h header and its logic in user space application, so we can add easy test for it. The test defines BTF_ID_LIST and checks it gets properly resolved. For this reason the test_progs binary (and other binaries that use TRUNNER* macros) is processed with resolve_btfids tool, which resolves BTF IDs in .BTF_ids section. The BTF data are taken from btf_data.o object rceated from progs/btf_data.c.
