Hello Vorbis folks, I'm one of the FFTW authors (www.fftw.org), and a few days ago I was playing with our codelet generator for fun and modified it to spit out hard-coded MDCTs of small sizes. The code (at jdj.mit.edu/~stevenj/mdct_128nr.c) for 256 samples (128 outputs) seems to be almost twice as fast as the Vorbis MDCT code for that size on my 2.2GHz P-IV (gcc 3.2.2 and flags "-O1

Hello, I would like to submit two papers that use LLVM to the Related Publications section. Both papers focus on code isolation applied to perform piecewise compiler optimizations. The code isolation process is performed by CERE, an open source tool based on LLVM. The second paper is an extended version of the first one. 1) Piecewise Holistic Autotuning of Compiler and Runtime Parameters

Dear Mihail, I've added these two publications to the publications page. Please review it and let me know if I need to make any changes. In particular, if you have URLs to use for the papers, having those would be greatly appreciated.

Dear R people, I am trying to install rimage using install.packages("rimage") but am receiving the following errors despite having FFTW installed. I would appreciate any help to get this fixed. checking fftw.h usability... no checking fftw.h presence... no checking for fftw.h... no configure: error: Sorry, can't find fftw header ERROR: configuration failed for package

So I now have a working first-order language that uses conventional boxing to handle polymorphism and with ints, floats and ('a -> 'a) functions. After a huge amount of detailed benchmarking in OCaml and F# I have decided that it is very important to be able to unbox complex numbers but no other compound types. As LLVM provides a vector type for power-of-two dimensionalities that

The rimage install can't find the ffw header. Any idea why?

I'm still having problems installing rimage - the installation can't find the fftw headers. As suggested, I installed the fftw rpm (for RH 9 from freshrpms). It installed without any errors or warnings. Yet I get exactly the same error message - it can't find the fftw headers. What do I have to do to get the headers? Rick B.

A somewhat random question: I'm wondering if there's any kind of trick in LLVM that would allow me to implement closures efficiently. We can assume that a closure function has a hidden parameter which points to its environment, that is, the values of the variables which were in scope at the point where the closure function was defined. The problem comes when mixing closure and

Hello All (to Ocaml List & CC LLVM list) As some might probably know, the LLVM compiler http://llvm.org/ has (at least in its latest SVN snapshot) a binding for Ocaml. This means that one could code in Ocaml some stuff (eg a JIT-ing compiler) which uses (and links with) LLVM libraries. http://lists.cs.uiuc.edu/pipermail/llvmdev/2007-November/011481.html

Hi folks: I am trying to install the package "rimage" in R 1.8.0 on an Alpha Linux box.

Hi people! I want to save the 1st letter from the ${EXTEN} variable. I don't want to trim it, I want to RESAVE it into a new variable. Let us assume the ${EXTEN} contains: 0698332977 then I'd love to get the 0 I would thank you for all advises. Tamer

I'm surprised you're happy with a non-polymorphic llvm. Does Cayenne target llvm? Dependent types take polymorphism to new heights -- but
