Subject: [RFC] perf top and deleted binaries
Date: Mon, 9 May 2011 11:28:23 -0700 [thread overview]
Message-ID: <20110509182822.GA23798@dev1756.snc6.facebook.com> (raw)
For long running binaries which may have been replaced or deleted, today
perf top spits out a warning and doesn't show anything. For eg:
test.c:
main()
{
while(1);
}
gcc -O2 test.c -o test
./test &
gcc -O2 test.c -o test # overwrite the binary
perf top -p <pid>
shows nothing. It could instead show:
100% <unresolved> test
like perf record/report would show for the same test case. Comments?
