Hi, I was wondering how I can print out the result of some arithmetic on 128 bit integers. After having a look at the API , it seems it is possible to get the integer value from the "ConstantInt::getSextValue() " but the return value is only a int64_t. I wish to print it on the console output and printing as a string or decimal ( using C standard library printf ) My Question :

Hi, I have been trying to move some instructions between basic blocks , After looking at the API , I found llvm::Instruction::clone() but there is no result value for this. For example- source Basic block : continuation: ; preds = %else, %then %iftmp = phi i32 [ 5, %then ], [ 9, %else ] store i32 %iftmp, i32* %datasize ; 3 instructions below

Hi, I was trying to print out a 128 bit result at runtime using a call to printf in LLVM. I am able to print 32 uptil 64 bit integers using the format string "%d" in printf . Please see the code in red below , as I am having a bit difficulty in trying to print the 128 bit value computed at runtime. The code in red is never executed since the value may never be casted to a

Hi, I was wondering if it was possible to create a Dummy Type by subclassing LLVM Type. I do not want to create a new type or even do much with this dummy type , all I need is a placeholder type until I generate IR. I want to use this approach as most of my AST is already configured to accept a Type* and not a DummyType* ( which is my own class ) I explored this a bit and did manage to

I was trying to run the simplify CFG Pass in LLVM , and delete an unreachable basic block ("continuation" below ) after running one of my own IR transforms , but I keep getting the error - While deleting: i8* %g Use still stuck around after Def is destroyed: store i8 0, i8* %g I am well aware of what that means, but isn't the whole purpose of the "simplifyCFGPass" to

Hi everyone, I just had a question - I am aware that LLVM supports it's own form of RTTI ( using dyn_cast<>() ,etc) but I wish to use C++ RTTI currently. I have tried building with "cmake -G "Unix Makefiles" -LLVM_ENABLE_RTTI=ON" but that doesnt seem to remove the "fno-rtti" flag from llvm-config and I still get an error when I try using

Dear all, I just created this revision <https://reviews.llvm.org/D34937> but I did not receive any email for it even though it says 'Automatically Subscribed' on the right. Also, even my profile shows no trace of the aforementioned revision. It shows that my last activity was on 24th May. Additionally, just to verify that I am not receiving any emails from Phabricator, I logged

Hey all, I have a piece of code (written in LLVM 2.8) which uses profiling results produced by ProfileInfo. It essentially computes the number of iterations performed by a loop from the profiling information available. The code snippet in my pass looks something like this. BasicBlock *header = loop->getHeader(); ProfileInfo &pi = getAnalysis< ProfileInfo >(); for(pred_iterator

Hello everyone, In the file *lib/CodeGen/AsmPrinter/AsmPrinter.cpp*, I would like to obtain an MCInst corresponding to its MachineInstr. Can anyone tell me a way to do that? If that is not possible, then, I would like to know if a given MachineInstr is an *lea *instruction and I would like to know if the symbol involved with this lea instruction is a jump-table. For instance, given a

Does anyone know how to make www.ud.com's Think Cancer Research Program Work under wine? I got it to install, but then it can't contact the server to register. Any ideas/suggestions? Thanks in advance, Dan W

Dear List, It's the first time that I try to request your support. I intent do use the BRB (Biased Random Bridge) function with a boundary. I believe I have made sure to fulfill all the rules for boundaries (segment length, angle of junction) When calculating the UD I get the following Error: Error in adehabitatHR:::.fbboun(sor2, boundary, sigg, max(so$h)) : non convenient sign Can

Hi, I want to add "mem2reg" pass similar to this: PassManager PM; PM.add(new LoopInfo()); PM.add(new Mem2Reg()); // What's the class name for this pass I couldn't find the name of corresponding class and header file of mem2reg pass except "mem2reg.cpp". So how can I add mem2reg pass into my pass manager? Thanks, Riyad -------------- next part -------------- An

Hello, I am used to specifying dependence on other LLVM passes in the `getAnalysisUsage(AnalysisUsage &)` method of my pass. However, it doesn't seem that there is a header file that exposes the `mem2reg` pass - it is implemented in `Mem2Reg.cpp` as a wrapper. Is there an easy way to reuse this pass, or should I, in essence, duplicate `Mem2Reg.cpp` in my project? Cheers, - Stan

Hi, I was trying to pass llvm option -mem2reg to clang using -mllvm and I found the following error: clang (LLVM option parsing): Unknown command line argument '-mem2reg'. Try: 'clang (LLVM option parsing) -help' clang (LLVM option parsing): Did you mean '-debug'? I would appreciate if anyone could help me. -- Syed Rafiul Hussain

Hello, I just upgraded my llvm to 5.0.0. I applied mem2reg pass as follows: opt -mem2reg m2rtttl.bc > m2rtttl.opt But after that, I compared m2rtttl.bc and m2rtttl.opt. I noticed that there are no difference between m2rtttl.bc and m2rtttl.opt. Did I apply llvm in the correct way? Thanks a lot for the help! Best, Linhai -------------- next part
