I don't know if there is something to do with my problem, but I'm using VMKit front-end to generate the .bc files. So, after generating the example.bc, I remove some redundant instructions with my pass with opt.

...ere if you haven't found this document: http://llvm.org/docs/WritingAnLLVMPass.html I'm going to assume you're using `opt -load MyPass.so -my-pass input.bc -o output.bc` in which case you can just run llc on output.bc to get a .s file.

Hi all, I´ve been working on a transformation pass which performs the remotion of some redundant instructions. So now it´s finished I´d like to run the optimized programs generated by my pass. But I´ve got some problems to do this, because I didn´t find a way to generate assembly from the code and then call the gcc compiler to produce machine-dependent code. Please, does anybody know how to run

Hi all, I wrote you some days ago about one project that I want to do on vmkit: I want to remove redundant instanceof tests. I am right now looking at the LLVM code that vmkit produces for java files, but I am finding it very difficult to identify the code that is produced by each instanceof. Would it be possible for you guys to give me some pointers on how to attack this problem? Should I

Hi Zoe, maybe you've already solved your problem with VMKit configuration, but here you can find a mini-tutorial that I've done to guide people on VMKit installation. http://www2.dcc.ufmg.br/laboratorios/llp/wiki/doku.php?id=afpf Best regards, Alysson On Wed, Jun 30, 2010 at 1:34 PM, nicolas geoffray < nicolas.geoffray at gmail.com> wrote: > Hi Zoe, > > Unfortunately, I

Hi Zoe, Unfortunately, I don't have access to a x64 machine anymore, so I can't test that architecture on vmkit. Could you install a virtual machine on your machine that is x86_32? I know it has been successfully built and ran on x86_32 on different systems. Cheers, Nicolas On Wed, Jun 30, 2010 at 7:49 AM, Zoe Wolk <zoewolk at gmail.com> wrote: > Hi again Nicolas, > >

Hi, LLVMers, I am a CS student in my final year, and I would like to use LLVM in my final course project. So, I just download LLVM and VMKit, and I have been playing with both. I can produce llvm bytecodes from java programs, and now my idea is to remove redundant type checks from the code. For instance, if we consider a program like this: if (o instanceof A) { A a = (A) o; // do

Hi LLVMers, I am working on my llvm school project optimization pass. It's relatively simple, and it tries to remove redundant bitcast instructions followed by load instructions. At first, I'm using as input a bytecode generated by a simple Java test program. I've already found the reduntant instructions by looking at it's CFG, and I also could implement the code to
