Dear list, I wish to visualise some 4D data as a kind of colour / translucent cloud in 3D. I haven't seen such plots in R (but perhaps I missed a feature of rgl). The easiest option I found would be to export the data in povray's df3 (density file) format and visualise it with povray. The format specification baffles me a little, http://www.povray.org/documentation/view/3.6.1/374/ ; fortunately I found a few C++ utilities that could do the conversion from a plain ascii datafile to this format. Basically, I wish to cr...

I'm using LLVM 2.2 and trying to run the external povray test. The LLVM Test Suite Guide (http://llvm.org/releases/2.2/docs/TestingGuide.html) Indicates that configuring with "--enable-povray=directory" will do the trick. Unfortunately that doesn't seem to work. Poking around the config files I saw that "--with-externals=directory&q...

...conservative because unlike dynamic/partial unrolling, fully unrolling will not affect LSD/ICache performance.

...performance regressions between 2.9 and 3.0: http://openbenchmarking.org/result/1110178-AR-1110173AR66 Identifying where these were introduced is quite difficult. I wonder if some of the buildbots could be persuaded, after building clang, to build and run some benchmark projects (e.g. perlbench, povray, flac / lame, whatever) and email people if they introduce a performance regression, just as the current buildbots email people who break the build.

...e=core2 and are getting compile-time errors on the gamess and tonto benchmarks. For the native x86-32 target, we are using the following command-line arguments: -O3 -march=core2 -mtune=core2 -m32 and are getting compile-time errors on gamess and tonto as well as run-time errors on gcc, cactus and povray. Are these known errors? If yes, are there any patches that fix them? Are there any patches for LLVM 2.9 at all? If yes, where can I find them?
