class SampleCoverageTracker

Declaration

class SampleCoverageTracker { /* full declaration omitted */ };

Declared at: llvm/include/llvm/Transforms/Utils/SampleProfileLoaderBaseUtil.h:35

Member Variables

private llvm::sampleprofutil::SampleCoverageTracker:: FunctionSamplesCoverageMap SampleCoverage

Each entry in the map corresponds to a FunctionSamples instance. This is another map that counts how many times the sample record at the given location has been used.

private uint64_t TotalUsedSamples = 0

Note that this accumulator tracks samples used from a single function and all the inlined callsites. Strictly, we should have a map of counters keyed by FunctionSamples pointers, but these stats are cleared after every function, so we just need to keep a single counter.

private bool ProfAccForSymsInList = false
