Comment at: llvm/tools/llvm-profdata/llvm-profdata.cpp:1089-1091
+ size_t NumToRemove = CalculateNumFunctionsToRemove(
+ OriginalFunctionCount, Functions->size(),
+ Writer->getOutputStream().tell(), OutputSizeLimit);
----------------
This heuristic can be quite inaccurate. The number of body sample + call site sample entries can be much better proxy for actual profile size and yet still easily accessible.
`functionSamples.getBodySamples().size() + functionSamples.getCallsiteSamples().size()`
