Hi All, I have a query regarding LLVM,Can LLVM IR can restore high level information of base language. Thanks and Regards, Manish On 5/18/07, manish <manishagg22 at gmail.com> wrote: > >

Hello I am developing a backend that generates OpenCL from llvm bitcode. I start with a revived fork of the original LLVM C-Backend and have been modifying it. One thing that the backend lacked was generating proper loop structures; instead it relied on labels and goto statements. Therefore, I am trying to find a way to identify the loop structure and print it out in the backend. So far, the main

Here is my current flow: in my "external accounts controller" 1) before_filter :ensure_authenticated_to_facebook, :only =&gt; [:authenticate_facebook, :edit_facebook] 2) when the user links into facebook, facebooker authenticates and redirects back to my application 3) i detect the

Hi, You might want to try running -loops -loop-simplify before loop unroll. >From loop simplify.cpp This pass performs several transformations to transform natural loops into a00011 // simpler form, which makes subsequent analyses and transformations simpler and00012 // more effective.

Even after all the sequence of commands below bit-code is not showing any effect of loop-unrolling *manish at manish:~/Test2$ llvm-gcc-4.2 -O2 -emit-llvm Hello.c -c -o Hello.bc* *manish at manish:~/Test2$ opt-2.8 -loops Hello.bc -o Hello1.bc* *manish at manish:~/Test2$ opt-2.8 -loopsimplify Hello1.bc -o Hello2.bc* *manish at manish:~/Test2$ opt-2.8 -indvars Hello2.bc -o Hello3.bc* *manish at

1. You should run the passes in the same opt command, for passes like loops which is an analysis pass provides results to the following passes. 2. You can pass a -debug flag to opt to see the some debugging info. 3. I tried this opt -mem2reg -loops -loopsimplify -loop-unroll -unroll-count=3 -debug loop.o -o tt.bc and got this message. Loop Size = 14 Can't unroll; loop not terminated by

I have a legacy C++ application that constructs a tree of C++ objects (an iterator tree to implement a query language). I am trying to use LLVM to "serialize" the state of this tree to disk for later loading and execution (or "compile" it to disk, if you prefer). Each of the C++ iterator objects now has a codegen() member function that adds to the LLVM code of an

There's a README.txt in the subversion repository: https://llvm.org/svn/llvm-project/hlvm/trunk/README.txt which says: HLVM comes with documentation in HTML format. These are provided in

What happened to the HLVM project? I understand it was intended to be a high-level VM specifically for dynamic languages and this post indicates that it was integrated into the LLVM project last year: http://www.nabble.com/NEWS:-HLVM-merges-with-LLVM-td9627113.html But I cannot find any code in LLVM that looks like it would have come from HLVM. -- Dr Jon Harrop, Flying Frog Consultancy

I took the first two lines of the sample program in the tutorial: hendrik at lovesong:~/dv/lang/hlvm$ cat broken.cpp #include "llvm/DerivedTypes.h" #include "llvm/Module.h" hendrik at lovesong:~/dv/lang/hlvm$ and tried to compile them using the llvm-dev in Debian testing: hendrik at lovesong:~/dv/lang/hlvm$ g++ -o broken.o -c broken.cpp In file included from

Someone is trying to work on HLVM with me but they're hitting a problem that we have not been able to resolve. Specifically, GCC seems to be performing some kind of sanity check for "stack smashing" and is calling abort because it is unhappy with something that the code is doing. However, I am not sure what and cannot reproduce the problem. The stack trace they have given me is:
