[PATCH] D110424: [llvm-profgen] Ignore invalid perf line in LBR record

[Wenlei He via Phabricator via llvm-commits]

wenlei added inline comments.


================
Comment at: llvm/tools/llvm-profgen/PerfReader.cpp:424
   if (!Records.empty() && Records[0].find('/') == StringRef::npos) {
     Index = 1;
   }
----------------
We need to make sure this is a number? 

Anything else we should check? Wondering if regex can make things easier and more robust.
