Hello, LLVM-Java has been rendered obsolete by http://vmkit.llvm.org/ so look into using VMKit instead. --Sam ----- Original Message ---- > From: Andre Tavares <andrelct at dcc.ufmg.br> > To: LLVMdev at cs.uiuc.edu > Sent: Monday, May 18, 2009 10:09:42 AM > Subject: [LLVMdev] llvm-java > > Hello, > > I'm working on a project to remove unnecessary array

Dear Community, I'm working on a project for Google Summer of Code, to implement the ABCD and Bitwidth analysis in LLVM. I'm not going to extend the description of the project here, this link shows my proposal http://homepages.dcc.ufmg.br/~andrelct/projects/gsoc_2009/proposal. I have been in some discussions on this list about Ada and SSI that helped on my decisions up to this

Hello, I'm working on a project to remove unnecessary array bound checks in Java. For this purpose I will need to use llvm-java. What is the state of llvm-java? Can someone explain how to build and use it? I saw some old emails on the list, and some about a SoC 2008 on Java, but I didn't find anything regarding its current state and documentation.

I'm developing the ABCD algorithm for LLVM, and I will need to store some information as a digraph. I was thinking of a list of adjacency, implemented with a map<Instruction, Set<Node>>. The node would have an Instruction and a value. I opted for map and set, because I will create the graph once and will search on it a bunch of times, and will never remove a node. Is there

Dear Nicolas, I'm curious why you are using ABCD in vmkit. Do you need any features from static array bounds checking? As far as I know, SAFECode has a number of implementation for that. Thanks.

Why not use SmallPtrSet instead of std::vector? Isn't there something in LLVM I can use?

Dear LLVM Community, I'm a Computer Science master student at UFMG, Brasil. I'm interested in taking part on Google Summer of Codes 2009. My idea is not on the LLVM list, but I have written a project description to make my intentions clear. My project is attached as a pdf file.

By static array bounds checking, I mean eliminating array bounds checking which can be proved ``safe'' at compile-time. Well, even though there are a lot of approaches of doing this, I believe that having an implementation of ABCD would very useful. It would be even more useful if LLVM can have a general framework for doing static array bounds checking -- just like the aliasing framework.

Dear Andre, That's great! Thanks for the blog. I am really looking forward into using ABCD in vmkit!

Hello, I'm trying to build LLVM-gcc to compile Ada. But I'm having a few problems. First thing I did was install gnat 2007. In the bin directory there is a gcc version 4.1. So I think that these versions are good for Ada. Now when I ran make I get an error that for me it seams very weird. ../../gcc/c-format.c: In function 'set_Wformat': ../../gcc/c-format.c:48: error:

Hi Andre, > In file included from ../../gcc/llvm-backend.cpp:23: > ../../gcc/llvm-internal.h:31: fatal error: vector: No such file or directory > compilation terminated. line 31 of llvm-internal.h is: #include <vector> so if that's failing then your C++ compiler is somehow borked. How did you arrange to use the right gcc for the build? Maybe that's getting in the way of

I tried to make 5 separate patches, but as they are constructive, they had information from the last one. So I will post one by one as it gets on the tree. 1. We had a function isUsedInTerminator that tested if a comparator was used in the terminator of its parent BasicBlock. This is wrong because a comparator can be created in a BasicBlock and used in the terminator of other BasicBlock, and

Dear LLVM community, In 2007 Lang Hames developed a Graph Coloring Register Allocator. This allocator was created based on the paper " A generalized algorithm for graph-coloring register allocation" (http://doi.acm.org/10.1145/996841.996875). This algorithm is graph based, and is concerned with register banks that have different register classes and registers that alias. Lang
