2013-05-02[GV] Remove dead code which is really difficult to decipher.Shuxin Yang
Actually it took me couple of hours trying to make sense of them and only to find they are dead code. I guess the original author used "allSingleSucc" to indicate if there are any critial edge emanating from some blocks, and tried to perform code motion (actually speculation) in the presence of these critical edges; but later on he/she changed mind and decided to perform edge-splitting first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180951 91177308-0d34-0410-b5e6-96231b3b80d8

No functionality changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180897 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-01This exposes more MCJIT options via the C API:Filip Pizlo
CodeModel: It's now possible to create an MCJIT instance with any CodeModel you like. Previously it was only possible to create an MCJIT that used CodeModel::JITDefault. EnableFastISel: It's now possible to turn on the fast instruction selector. The CodeModel option required some trickery. The problem is that previously, we were ensuring future binary compatibility in the MCJITCompilerOptions by mandating that the user bzero's the options struct and passes the sizeof() that he saw; the bindings then bzero the remaining bits. This works great but assumes that the bitwise zero equivalent of any field is a sensible default value. But this is not the case for LLVMCodeModel, or its internal equivalent, llvm::CodeModel::Model. In both of those, the default for a JIT is CodeModel::JITDefault (or LLVMCodeModelJITDefault), which is not bitwise zero. Hence this change introduces LLVMInitializeMCJITCompilerOptions(), which will initialize the user's options struct with defaults. The user will use this in the same way that they would have previously used memset() or bzero(). MCJITCAPITest.cpp illustrates the change, as does the comment in ExecutionEngine.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180893 91177308-0d34-0410-b5e6-96231b3b80d8

2013-05-01This patch breaks up Wrap.h so that it does not have to include all of Filip Pizlo
the things, and renames it to CBindingWrapping.h. I also moved CBindingWrapping.h into Support/. This new file just contains the macros for defining different wrap/unwrap methods. The calls to those macros, as well as any custom wrap/unwrap definitions (like for array of Values for example), are put into corresponding C++ headers. Doing this required some #include surgery, since some .cpp files relied on the fact that including Wrap.h implicitly caused the inclusion of a bunch of other things. This also now means that the C++ headers will include their corresponding C API headers; for example Value.h must include llvm-c/Core.h. I think this is harmless, since the C API headers contain just external function declarations and some C types, so I don't believe there should be any nasty dependency issues here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180881 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-30LocalStackSlotAllocation improvementsHal Finkel
First, taking advantage of the fact that the virtual base registers are allocated in order of the local frame offsets, remove the quadratic register-searching behavior. Because of the ordering, we only need to check the last virtual base register created. Second, store the frame index in the FrameRef structure, and get the frame index and the local offset from this structure at the top of the loop iteration. This allows us to de-nest the loops in insertFrameReferenceRegisters (and I think makes the code cleaner). I also moved the needsFrameBaseReg check into the first loop over instructions so that we don't bother pushing FrameRefs for instructions that don't want a virtual base register anyway. Lastly, and this is the only functionality change, avoid the creation of single-use virtual base registers. These are currently not useful because, in general, they end up replacing what would be one r+r instruction with an add and a r+i instruction.

2013-04-30Refactoring patch.Stepan Dyatkovskiy
1. VarArgStyleRegisters: functionality that emits "store" instructions for byval regs moved out into separated method "StoreByValRegs". Before this patch VarArgStyleRegisters had confused use-cases. It was used for both variadic functions and for regular functions with byval parameters. In last case it created new stack-frame and registered it as VarArg frame, that is wrong. This patch replaces VarArgsStyleRegisters usage for byval parameters with StoreByValRegs method. 2. In ARMMachineFunctionInfo, "get/setVarArgsRegSaveSize" was renamed to "get/setArgRegsSaveSize". By the same reason. Sometimes it was used for variadic functions, and sometimes for byval parameters in regular functions. Actually, this property means the size of registers, that keeps arguments, and thats why it was renamed. 3. In ARMISelLowering.cpp, ARMTargetLowering class, in methods computeRegArea and StoreByValRegs, VARegXXXXXX was renamed to ArgRegsXXXXXX still by the same reasons. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180774 91177308-0d34-0410-b5e6-96231b3b80d8
