Jakob Stoklund Olesen 43cda021d9 Fix inline cost predictions with SCIENCE. ... After running a batch of measurements, it is clear that the inliner metrics need some adjustments: Own argument bonus: 20 -> 5 Outgoing argument penalty: 0 -> 5 Alloca bonus: 10 -> 5 Constant instr bonus: 7 -> 5 Dead successor bonus: 40 -> 5*(avg instrs/block) The new cost metrics are generaly 25 points higher than before, so we may need to move thresholds. With this change, InlineConstants::CallPenalty becomes a political correction: if (!isa<IntrinsicInst>(II) && !callIsSmall(CS.getCalledFunction())) NumInsts += InlineConstants::CallPenalty + CS.arg_size(); The code size is accurately modelled by CS.arg_size(). CallPenalty is added because calls tend to take a long time, so it may not be worth it to inline a function with lots of calls. All of the political corrections are in the InlineConstants namespace: IndirectCallBonus, CallPenalty, LastCallToStaticBonus, ColdccPenalty, NoreturnPenalty. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94615 91177308-0d34-0410-b5e6-96231b3b80d8		2010-01-26 23:21:56 +00:00
