search for: inst2

...r. I am writing a ModulePass that insert new instruction to an existing Module. Besides, how can you get a reference to myreg1 ? Looking at your snippet this variable would be a llvm::Value* (I saw that in the documentation of IRBuilder). All I have in my code is something like: llvm::LoadInst *inst2 = new llvm::LoadInst( oneGlobalVariable, "myreg1", inst1); Probably I can get a Value pointer to the output register from the inst2 variable, but I don't know how (I couldn't figure out myself by just reading the documentation). Any help is very welcome, Eduardo

I've got a suggestion for a refinement: Right now, we have classes like DILocation that wrap an MDNode* to provide more convenient access to it. It would be more convenient for users if instead of MDNode *DbgInfo = Inst->getMD(MDKind::DbgTag); Inst2->setMD(MDKind::DbgTag, DbgInfo); they could write: DILocation DbgInfo = Inst->getMD<DILocation>(); inst2->setMD(DbgInfo); we'd use TheContext->RegisterMDKind<MyKindWrapper>() or ...Register<MyKindWrapper>("name"); to register a new kind. (I prefer...

I have been looking over the doxygen documentation as well as the llvm code. Is there a standard way to check to see if two instructions are identical (i.e., Inst1 == Inst2 does not work)? Thanks, Brian Brian M. Fahs Graduate Student University of Illinois

Hi all, I want to find memory dependency between CallInst instruction and other. So i used the following code: * AliasAnalysis &AA=getAnalysis<AliasAnalysis>();* * if(isa<StoreInst>(inst1)){* * ** **if(isa<CallInst>(inst2))**{* * CallInst *call_inst2= dyn_cast<CallInst>(inst2); * * if(AA.getModRefInfo(inst1,call_inst2)==mod)**{* * //* * } * * }* * }* but i get the following error. I should what do for exrtact memory dependency between CallInst instruction and o...

Comparing pointers will tell you if they are the SAME instruction. I think what Brian is looking for is "equivalent" instructions, as I am famil...

...is it correct to say that the last dependent instruction in each visited basic block is what is mapped ? For example, if a basicblock B has two instructions: B: store i32 1, i32* %i, align 4 (say inst1) ... load i32* %i, align 4 ; <i32>:39 [#uses=1] (say inst2) and suppose i had one more Store instruction to %i outside B which is the query, then when B is visited, in the DenseMap only the mapping <B, inst2> is added and not <B, inst1> ? I am guessing that this information is sufficient for most code-hoisting optimizations since just the kno...

If you want to check if two instructions are the same instruction, you should be able to just compare pointers. -Tanya

Hello everyone, I am running into an obscure issue with ExpandPostRA. Does anyone recognizes the following: The pass replaces a real copy with a "transfer" instruction: ********** EXPANDING POST-RA PSEUDO INSTRS ********** ********** Function: main real copy: %R15<def> = COPY %R4, %D2<imp-use,kill>, %D7<imp-use,kill>, %D7<imp-def> replaced by:

Hi, You'd use an IRBuilder, like you did to create your LoadInsts. IRBuilder<> IRB(BB); IRB.CreateGEP(myreg1, myreg2); I assume because you asked this question, something went wrong when using the above method. What was it? :) Cheers, James ________________________________________ From: llvmdev-bounces at cs.uiuc.edu [llvmdev-bounces at cs.uiuc.edu] On Behalf Of Eduardo [erocha.ssa

Hi all, How can I create an llvm::GetElementPtrInst in which the pointer and the index are in registers previously loaded with llvm::LoadInst ? I mean, the generated instruction will be like this: %1 = getelementptr i8* %myreg1, i32 %myreg2 here, %myreg1 and %myreg2 are previously created by load instructions (llvm::LoadInst). Please, let me know if there is an example of something similar.

Hi, I have a question about the memory dependence analysis. I am trying to use it to selectively enumerate a set of pairs of (load, store) instructions for every function by calling getNonLocalDependency() on the MemoryDependenceAnalysis. This populates a DenseMap<BasicBlock*, Value*>. I just looked up an usage of this in GVN.cpp: MD->getNonLocalDependency(C, deps); for
