◆ getPromotionCandidatesForInstruction()

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

Returns reference to array of InstrProfValueData for the given instruction I.

The NumVals, TotalCount and NumCandidates are set to the number of values in the array, the total profile count of the indirect call 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.
