[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,

[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
