[PATCH] D144500: [BOLT] initial version of stale profile matching

[Amir Ayupov via Phabricator via llvm-commits]

Amir added inline comments.


================
Comment at: llvm/lib/Transforms/Utils/SampleProfileInference.cpp:1325
+/// profi options
 void llvm::applyFlowInference(const ProfiParams &Params, FlowFunction &Func) {
+  // Check if the function has samples and assign initial flow values
----------------
There's an issue in shared build mode:
```
ld.lld: error: undefined symbol: llvm::applyFlowInference(llvm::ProfiParams const&, llvm::FlowFunction&)
>>> referenced by StaleProfileMatching.cpp
>>>               tools/bolt/lib/Profile/CMakeFiles/LLVMBOLTProfile.dir/StaleProfileMatching.cpp.o:(llvm::bolt::applyInference(llvm::FlowFunction&))
```
