$clang -g -S -emit-llvm -o loopy.ll loopy.c
$ operf -Vdebug -e CPU_CLK_UNHALTED:5000000 lli

Using samples dir /home/dad/oprofile_data/samples
Kernel profiling is not possible with current system config
Set /proc/sys/kernel/kptr_restrict to 0 to collect kernel samples.
Exec args are: lli -debug-only=oprofile-jit-event-listener loopy.ll
telling child to start app
app 47033 is running
parent says start app /usr/local/bin/lli
