2010-01-27Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes GlobalValues now, and doesn't provide modules, it's renamed to "GVMaterializer". Code that used to need a ModuleProvider to materialize Functions can now materialize the Functions directly. Functions no longer use a magic linkage to record that they're materializable; they simply ask the GVMaterializer. Because the C ABI must never change, we can't remove LLVMModuleProviderRef or the functions that refer to it. Instead, because Module now exposes the same functionality ModuleProvider used to, we store a Module* in any LLVMModuleProviderRef and translate in the wrapper methods. The bindings to other languages still use the ModuleProvider concept. It would probably be worth some time to update them to follow the C++ more closely, but I don't intend to do it. Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94686 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-27Eliminate target hook IsEligibleForTailCallOptimization.Evan Cheng
Target independent isel should always pass along the "tail call" property. Change target hook LowerCall's parameter "isTailCall" into a refernce. If the target decides it's impossible to honor the tail call request, it should set isTailCall to false to make target independent isel happy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94626 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-26use EmitLinkage for functions as well as globals. One outputChris Lattner
change is that we now use ".linkonce discard" for global variables instead of ".linkonce samesize". These should be the same, just less strict.

2010-01-26Fix inline cost predictions with SCIENCE.Jakob Stoklund Olesen
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
