The perf probe command has some exclusive options. Use new PARSE_OPT_EXCLUSIVE flag to simplify the code and show more compact usage. $ perf probe -l -a foo Error: switch `a' cannot be used with switch `l' usage: perf probe [<options>] 'PROBEDEF' ['PROBEDEF' ...] or: perf probe [<options>] --add 'PROBEDEF' [--add 'PROBEDEF' ...] or: perf probe [<options>] --del '[GROUP:]EVENT' ... or: perf probe --list or: perf probe [<options>] --line 'LINEDESC' or: perf probe [<options>] --vars 'PROBEPOINT' -a, --add <[EVENT=]FUNC[@SRC][+OFF|%return|:RL|;PT]|SRC:AL|SRC;PT [[NAME=]ARG ...]> probe point definition, where GROUP: Group name (optional) EVENT: Event name FUNC: Function name OFF: Offset from function entry (in byte) %return: Put the probe at function return SRC: Source code path RL: Relative line number from function entry. AL: Absolute line number in file. PT: Lazy expression of line code. ARG: Probe argument (local variable name or kprobe-tracer argument format.) -l, --list list up current probe events Signed-off-by: Namhyung Kim <namhyung@kernel.org> Acked-by: Hemant Kumar <hemant@linux.vnet.ibm.com> Acked-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: David Ahern <dsahern@gmail.com> Cc: Hemant Kumar <hemant@linux.vnet.ibm.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1413990949-13953-6-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
