perf tools: Make stat/record print fatal signals of the target program
When a program crashes under perf there is no message about it, unlike when running it from bash. This can be confusing and lead to wrong actions during debugging. Print fatal signals in perf stat/record. Thanks to Furat Afram for finding the problem originally Link: http://lkml.kernel.org/r/1316122302-24306-1-git-send-email-andi@firstfloor.org Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Stephane Eranian <eranian@google.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
