[LLVMdev] Instruction Cost
CostModule::getInstructionCost also consults TTI ( http://llvm.org/docs/doxygen/html/CostModel_8cpp_source.html#l00380). No?

[LLVMdev] Does LLVM have Instruction Performance Model?
Hi, Does LLVM define some performance model for each type of instructions? I mean the cost or latency for executing each type of instruction. Thanks a lot! Best, Linhai

[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
