...ct the induction variable. Can you run the loop vectorizer with the '-debug' option and check why it fails ?

Hi all, Sorry if this is a dumb or FAQ or the wrong list! I'm currently investigating LLVM vectorization of my generated code. My codegen emits a lot of recursions that step through arrays via pointers. The recursions are nicely optimized into loops, but the loop vectorization can't seem to work on them because of phi nodes that point to gep nodes. Some simple IR to demonstrate; it

Hi, few months ago I started a thread about running PWGL under wine. PWGL is a " free cross-platform visual language based on Common Lisp, CLOS and OpenGL, specialized in computer aided composition and sound synthesis. " http://www2.siba.fi/PWGL/index.html However, because I had to use winetricks to install Microsoft Visual C++ 2005 (it's needed by PWGL), and the many errors that I got running PWGL, I stopped investigating further. However, today I installed wine 1.1.8 under Ubuntu 8.04 and the situation looks promising: I cou...

I work primarily with Visual Studio and LLVM myself and have absolutely no objection to dropping VS2010. In fact, I stronly support such a move, as the VC++ compiler has improved quite a bit recently, especially in the

Hello, I'm new on this list. First of all, thank you to all the developers of this great project! At the moment there is only an application that keeps me on both macos and windows, its name is PWGL a free environment for computer assisted composition in openGL. (http://www2.siba.fi/PWGL/) I'm running Ubuntu 8.04 and wine 0.9.59. I have to say that I also installed vcrun2005 and vcrun2005sp1(using winetricks) in order to have Microsoft.VC80.CRT DLL in my system. The program starts, but after the initial stage (showing splash screen), it quits with the following error:...

Dear LLVM devs, If one were to (academically) cite the LLVM project in the general sense, what would be the recommended reference - ie. one that gives a recent and complete overview of the system? Thanks! Vesa

Hi, For libfaust, perhaps? :) Could it be something as simple as a target triple defined for the module? Without knowledge of the target machine vector width, the vectorizer will assume maximum width of 1. You can override this without a triple by using the -force-vector-width switch.

Hi all, Is there an efficient way to construct an AttributeSet for the purpose of constructing a Function? The only (public) way I've found to designate the parameter index of attributes is via the addAttribute methods of the Function class or the AttributeSet. This is quite inefficient as a new AttributeSet is constructed every time. In fact, it takes the bulk of the time my codegen
