Thanks, Eranian, statically link work fine.
BTW, I check the Intel manual, there is a even to count
"Cycles_not_issuing_uops":
Cycles_not_issuing_uops: This can be measured by event RS_UOPS_DISPATCHED,
setting the INV bit and specifying a counter mask(CMASK) value of 1 in the
target performance event select (IA32_PERFEVSELx) MSR. In Vtune, this event
name is RS_UOPS_DISPATCHED.CYCLES_NONE;
Cycles_issuing_uops: Counter part of the above metrics.
But I just found the event RS_UOPS_DISPATCHED_CYCLES:PORT[0, 5]/ANY, no
RS_UOPS_DISPATCHED.CYCLES_NONE. How can I get
RS_UOPS_DISPATCHED.CYCLES_NONE?
Thanks.
