Hello All, I want to dertermine whether a basicblock is in a conditional branch. such as, //============================= if a > 2 // BasicBlock A then BasicBlock B endif BasicBlock C //============================= What I want to identify is BasicBlock B, which is in a condtional block. but C is not. In other words, I want to distinguish Basi...

Hello, we can get BasicBlock from MachineBasicBlock through MachineBasicBlock::getBasicBlock() function, but how can I get MachineBasicBlock of a BasicBlock? Thank you!

Hello, I am a beginner of LLVM. I am trying to move among the instructions of a BasicBlock and I cannot. In this particular example, I try to get the previous instruction of the end instruction. I am trying 2 methods: 1. I have the following sequence of code: bool patternDC::runOnBasicBlock(BasicBlock &BB) { ... if (BB.getTerminator()) { Instruction* current = BB.ge...

...with branches as terminators on your way. If such parent exist, you mark that there is exist a direct connection between this parent and BB. What do you mean by "there are no BB with branches as terminators on your way" ? I remember All BB end with a terminator.... Well, I think if the basicblock only has one predecessor block, it also means its predecessor and iteself have direct connection. Do you mean this? > > Anyway I think it's impossible to detect all of such BB - you have indirect jumps, you can have a complicated branch structure with implicit flows that are hard to ana...

I don't think you can. The BasicBlock is a member of MachineBasicBlock. It is not inherited, so it cannot be cast. The number of the MachineBasicBlock is not the same as any BasicBlock values. So MachineFunction::getMachineBasicBlock( BasicBlock::{get the number} ) cannot work. I do not see much in the basic block which can identify it...

Hi, I am using LLVM to develop a tool, using Mac OS 10.9. I have download llvm source and binary from http://llvm.org/releases/download.html I just find the BasicBlock.h file of the binary package clang+llvm-3.6.0-x86_64-apple-darwin/include/llvm/IR/BasicBlock.h is slightly different from that of the source llvm/include/llvm/IR/BasicBlock.h In particular, llvm:: getModule(..) is included in the latter BasicBlock.h but not in the former BasicBlo...

...impossible to detect all of such BB - you have indirect jumps, you can have a complicated branch structure with implicit flows that are hard to analyse - like this: a = 0; b = 1; if (X == 1) a = 1; if (X == 0) b = 0; if (a == 0) Y = 0; if (b == 1) Y = 1; // in the end Y = X if(X == Y) BasicBlock C endif BasicBlock D In this example BasicBlock C is *must* executed, however it's hard to detect that it is. -- Yaroslav Markov PhD student in Computer Science Stony Brook University ________________________________________ From: llvmdev-bounces at cs.uiuc.edu [llvmdev-bounces at cs.uiuc.ed...

Hi, LLVM provides basic graph traversal for its CFGs, but I need additional operations, such as iterating over the edges. I thought I would solve this problem using the Boost graph library. It should be relatively simple to walk an LLVM CFG and add the BasicBlock objects to a Boost graph declared as: typedef boost::directed_graph<llvm::BasicBlock> Graph; Once constructed, this automatically gives me access to all kinds of sophisticated graph routines. Unfortunately, the above code doesn't compile because Boost apparently needs the cla...

Hi, Can anyone tell me if there's a straighforward way to create a new BasicBlock without inserting it into a function's basic block list? I want to do this so I can create a forward reference to a block that's position in the function is not yet known. I've tried: Function function Builder builder; bb = BasicBlock::Create(function,...) bb.eraseFromParent() ... a...

Dear all, Is there a way to check whether we can go from A to B within a function when I'm writing a pass? Thanks. Best, --Wenbin -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20100827/8cf26762/attachment.html>

I assume you are asking whether control flow can pass from BasicBlock A to BasicBlock B. In that case, yes: all you need to do is look at the terminator instruction of BasicBlock A and see if it can branch to BasicBlock B. There's a new indirect branch instruction; I don't believe it is used very often. You might have to handle those specially, but I'll...
