event not found - cannot create event uops_dispatched_port:port_0
LLVM ERROR: invalid perf event 'uops_dispatched_port:port_0'
I'm running this on a i7-4790K. Am I missing something on my computer or is this not yet fully implemented...

Inverse_throughput doesn't use the uops counters, so for example, the instruction layout shared between these two modes is really...
