[llvm-exegesis] Uops mode isnćt working
Hello,
I've been testing llvm-exegesis on X86. Latency and inverse_throughput modes work fine but when I run uops I get an error:
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?

[LLVMdev] Build Attributes Proposal
...vm.attribute]
[%llvm.attribute { i32 1, i8* getelementptr inbounds ([3 x i8]* @.str,
i32 0, i32 0) }, %llvm.attribute zeroinitializer], align 4
@.str = private constant [3 x i8] c"O3\00"
And the target-specific has something like the CPU name and whether
it's using R9 as SB:
// 5 is CPU_name in ARM ABI, 14 is ABI_PCS_R9_use
@llvm.arm.attributes = appending global [2 x %llvm.attribute]
[%llvm.attribute { i32 5, i8* getelementptr inbounds ([10 x i8]*
@.str1, i32 0, i32 0) }, %llvm.attribute { i32 14, i8* null }], align
4
@.str1 = private constant [10 x i8] c"ARM946E-S\00"
Do...
