perf probe: Make --line checks validate C-style function name
Fix --line to check valid C-style function name and returns a semantic error if it is not. For example, previously, --line doesn't support lazy pattern but it doesn't recognized as a semantic error. ---- # perf probe -L 'func;return*:0-10' Specified source line is not found. Error: Failed to show lines. ---- With this patch, it is correctly handled as a semantic error. ---- # perf probe -L 'func;return*:0-10' Semantic error :'func;return*' is not a valid function name. ... ---- Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Ananth N Mavinakayanahalli <ananth@in.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Hemant Kumar <hemant@linux.vnet.ibm.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20150506124647.4961.99473.stgit@localhost.localdomain Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
