| |
Adding test for build id cache that adds binary with sha1 and md5 build ids and verifies it's added properly.
The test updates build id cache with perf record and perf buildid-cache -a.
Signed-off-by: Jiri Olsa <jolsa@kernel.org> --- v3 changes: - compile examples directly in the test - using 'command' instead of 'which' for detection
