[PATCH] D53850: Declares __cpu_model as hidden symbol

2018-10-29 Thread Craig Topper via Phabricator via cfe-commits

craig.topper added inline comments.



Comment at: lib/CodeGen/CGBuiltin.cpp:9013
   Features, llvm::ConstantInt::get(Int32Ty, FeaturesMask));
   return Builder.CreateICmpNE(Bitset, llvm::ConstantInt::get(Int32Ty, 0));
 }

This code looks to be out of date. It's missing the changes from r344832 that 
added another runtime variable that presumably has the same issue.
