The attached patch contains: - Cleanups in the DAGCombiner.cpp ROTL/ROTR combine code, primarily helping me to fix 80col violations (benefiting the code as a whole). - Detect sign/zext/any-extended versions of ROTL/ROTR patterns. - Allow custom lowering for ROTL/ROTR (needed in the CellSPU's case for 8-bit rotates, when only 16-bit and 32-bit rotates are actually implemented in the

Hi Óscar, But if I do "I1->getOperand(0)->getOperand(0)" I get " ‘class llvm::Value’ has no member named ‘getOperand’ ". getOperand() I think it's only defined for Instruction class. Do you know any equivalent method for Value? On Fri, Jan 11, 2013 at 12:07 PM, Óscar Fuentes <ofv at wanadoo.es> wrote: > Alexandru Ionut Diaconescu

Hi Duncan, Thank you for your response! Now it works. But I have another problem: Do you know how can I iterate through a Value*? For instance, I have : Instruction *I1; // I take only I1 that are ICmp errs()<<"\n "<<*I1->getOperand(0)<<" \n"; // %3 = load i32* %c, align 4 As expected. Now I want to get %c from the previous to use "%c" in

Hello everyone, Can you please tell me if it is possible in LLVM to cast a `Value*` to an `Instruction*/LoadInst*` if for example `isa<LoadInst>(MyValue)` is true? In my particular piece of code: Value* V1 = icmpInstrArray[i]->getOperand(0); Value* V2 = icmpInstrArray[i]->getOperand(1); if (isa<LoadInst>(V1) || isa<LoadInst>(V2)){ ...

Hello everyone ! In my pass I inspect the penultimate instruction from every basic block in runOnFunction(). I am interested in ICMP instructions only. if(BB->size()>1) if(last->getPrevNode()) { previous = last->getPrevNode(); ok=1; } I want to get the operands of previous, which is of type Instruction*. Due tests based on getNumOperands, ICMP has 2 (as

Hello everyone ! In my LLVM pass, there is `Intruction* I1`. All the used "I1"s are ICMP instructions. *I1->getOperand(0) returns a `Value*` type. From errs()<<"\n"<<*I1->getOperand(0)<<"\n"; //printed : %3 = load i32* %c, align 4 Printed as expected. But I want to use %c. Do you know how I can get %c ? I need to use the value %c in

Hi All,   Can we extract name of variable name from "MDNode" ?   1. Neither temp_MDNode->getName() nor temp_MDNode->getValueName() give me "global_int" which is name of a variable.   2. I tried below ways as well. DIVariable DV(mdnode1); Value *v = mdnode1->getOperand(0);//gives add 0x69   3. I have written below code to reach till variable name.        LLVMIname is

Hi! I added 2 more tests and also refined an assert statement. Applies cleanly to r148473 now. Are there more comments on the code? Thank you!!

Hi All, In SVN head, MipsISelDAGToDAG.cpp has the following optimization: // Operand is a result from an ADD. if (Addr.getOpcode() == ISD::ADD) { // When loading from constant pools, load the lower address part in // the instruction itself. Example, instead of: // lui $2, %hi($CPI1_0) // addiu $2, $2, %lo($CPI1_0) // lwc1 $f0, 0($2) // Generate: //

I am currently working on DAGToDAGISel class for MIPS and am trying to figure out a way to use INTRINSIC_W_CHAIN for an intrinsic which can return a value. My intrinsic is defined as: Intrinsic<[llvm_i32_ty],[llvm_i32_ty,llvm_i32_ty,llvm_i32_ty,llvm_i32_ty],[IntrReadWriteArgMem]>; i.e. it has four arguments and one return value In DAGToDAGISel when I try to pass it with four arguments and

If I1->getOperand(0) is the load, then %c is its pointer argument available with: LoadInst *LD = cast<LoadInst>(I1->getOperand(0)); Value *C = LD->getPointerOperand(); On Fri, Jan 11, 2013 at 7:19 AM, Alexandru Ionut Diaconescu < alexandruionutdiaconescu at gmail.com> wrote: > Hello everyone ! > > In my LLVM pass, there is `Intruction* I1`.
