...#39;re interested in. The way to do this is to introduce a simple pointer expression language. This should be able to express things like: "The immediate for this call points at symbol foo". Symbolically, what I have in mind would look something like: // some asm ... # assert *(inst1 + 1) = foo inst1: callq foo // some asm... Here we add the "inst1" label to give us a address from which we can get at the immediate for the call. The " + 1" expression skips the call opcode (we know the size of the opcode ahead of time, since this is assembly...

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...

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

...e reverse Control Flow Graph starting at the query instruction's block, 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 infor...

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

...ting 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

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

...ng access the bits in their sections only. For example, there could be 3 rounds of discriminator assigning: the base discriminator which corresponds to existing discriminator assigning, discriminator for pass N, and discriminator for pass M. Let’s assume each round uses 4 bits. If the instruction Inst1 is from BB0 and it’s copied to BB1, it will have a discriminator 0x1. If BB1:Inst1 is copied to BB2:intr2 before Pass N, this instruction will have a new discriminator of 0x11 associated with pass N. Similarly, each copy of Inst1 before Pass M will have its own discriminators using bit 8 to bit 12....

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.
