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, 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

Thanks Alysson. Unfortunately, those instructions don't work for me (I followed them exactly using a clean system) -- probably because of the recent changes to the svn heads. After fixing EscapeAnalysis in vmkit to use the updated CallInst.getArgOperand interface I hit the error below. I was interested in using mmtk with the system (as recommended), but that requires a llvm-gcc build (and

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

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.

Thank you for the answer Reid. I've been already using the format `opt -load MyPass.so -my-pass input.bc -o output.bc`. But my problem is to execute the .s generated file. As long as I know, gcc compiler is capable to generate target machine code from assembly. So I tried to compile it with gcc to generate machine code, but there was many problems. Is there any way to compile and run .s files?

How are you getting LLVM to run your pass? There's plenty of information here 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.

You can pass the entire df, example: > data(iris) > iris$sp = as.character(iris$Species) > o=.jarray(lapply(iris, .jarray)) > .jcall("C",,"df",o) df, 6 variables [0]: double[150] [1]: double[150] [2]: double[150] [3]: double[150] [4]: int[150] [5]: String[150] Java code: public class C { static void df(Object df[]) { int n;

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

Hey, Ive installed web meetme and everything is working fine except no records are being written to the cdr and participants tables, this is because the cbEnd.php script is not running. Below is the output of the cbEnd.php when I run in manually. I am running asterisk 1.4.20.1 and web meetme 3.1.0 and the latest release's of PEAR,PHP and MySQL. ./cbEnd.php PHP Strict Standards: Assigning

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

Hello ! I want some piece of advice regarding a LLVM pass.
