Methods

¶ICallPromotionAnalysis(
    const llvm::ICallPromotionAnalysis& other)

Declared at: llvm/include/llvm/Analysis/IndirectCallPromotionAnalysis.h:43

Parameters

const llvm::ICallPromotionAnalysis& other

¶ICallPromotionAnalysis()

Declared at: llvm/include/llvm/Analysis/IndirectCallPromotionAnalysis.h:48

¶uint32_t getProfitablePromotionCandidates(
    const llvm::Instruction* Inst,
    uint32_t NumVals,
    uint64_t TotalCount)

Declared at: llvm/include/llvm/Analysis/IndirectCallPromotionAnalysis.h:38

Parameters

const llvm::Instruction* Inst

uint32_t NumVals

uint64_t TotalCount

¶ArrayRef<InstrProfValueData>
getPromotionCandidatesForInstruction(
    const llvm::Instruction* I,
    uint32_t& NumVals,
    uint64_t& TotalCount,
    uint32_t& NumCandidates)

Description

Returns reference to array of InstrProfValueData for the given instruction \p I. The \p NumVals, \p TotalCount and \p NumCandidates are set to the number of values in the array, the total profile count of the indirect call \p I, and the number of profitable candidates in the given array (which is sorted in reverse order of profitability). The returned array space is owned by this class, and overwritten on subsequent calls.
