Clement Courbet 17ad6e2f24 Revert "[llvm-exegesis] Add benchmark latency option on X86 that uses LBR for more precise measurements." ... From @erichkeane: ``` This patch doesn't seem to build for me: /iusers/ekeane1/workspaces/llvm-project/llvm/tools/llvm-exegesis/lib/X86/X86Counter.cpp: In function ‘llvm::Error llvm::exegesis::parseDataBuffer(const char*, size_t, const void*, const void*, llvm::SmallVector<long int, 4>*)’: /iusers/ekeane1/workspaces/llvm-project/llvm/tools/llvm-exegesis/lib/X86/X86Counter.cpp:99:37: error: ‘struct perf_branch_entry’ has no member named ‘cycles’ CycleArray->push_back(Entry.cycles); I'm on RHEL7, so I have kernel 3.10, so it doesn't have 'cycles'. According ot this: https://elixir.bootlin.com/linux/v4.3/source/include/uapi/linux/perf_event.h#L963 kernel 4.3 is the first time that 'cycles' appeared in this structure. ```		2020-07-17 16:55:17 +02:00
