class ProfileSummaryBuilder

Declaration

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

Declared at: llvm/include/llvm/ProfileData/ProfileCommon.h:40

Member Variables

private std::map<uint64_t, uint32_t, std::greater<uint64_t>> CountFrequencies

We keep track of the number of times a count (block count or samples) appears in the profile. The map is kept sorted in the descending order of counts.
