[LLVMdev] Instruction Cost
Hi,
I'm looking for APIs that compute instruction costs, and noticed several of
them.
1. A series of APIs of TargetTransformInfo that compute the cost of
instructions of a particular type (e.g. getArithmeticInstrCost and
getShuffleCost)
2. TargetTransformInfo::getOperationCost
3. CostModel::getInstructionCost::getInstructionCost in
lib/Analysis/CostModel.cpp
Only the first one is used
