Yafang Shao 6a8faf1070 bpftool: Fix build warnings with -Wtype-limits ... Quentin reported build warnings when building bpftool : link.c: In function ‘perf_config_hw_cache_str’: link.c:86:18: warning: comparison of unsigned expression in ‘>= 0’ is always true [-Wtype-limits] 86 | if ((id) >= 0 && (id) < ARRAY_SIZE(array)) \ | ^~ link.c:320:20: note: in expansion of macro ‘perf_event_name’ 320 | hw_cache = perf_event_name(evsel__hw_cache, config & 0xff); | ^~~~~~~~~~~~~~~ [... more of the same for the other calls to perf_event_name ...] He also pointed out the reason and the solution: We're always passing unsigned, so it should be safe to drop the check on (id) >= 0.
