Hi all, I did a performance test of two real applications (FFMPEG and GTK) on ARM. For more details see: http://laurovenancio.wordpress.com/2007/08/07/llvm-perf-tests/ Lauro
This is pretty awesome. Thanks Lauro! Evan On Aug 13, 2007, at 4:10 PM, Lauro Ramos Venancio wrote:> Hi all, > > I did a performance test of two real applications (FFMPEG and GTK) on > ARM.

Hi, I have two related questions: Are there LLVM developers on this list that are interested in improving LLVM performance? I have examples in which LLVM is slower than gcc (e.g., STM linked list microbenchmark, 1.8 (gcc) vs. 1.3 (llvm), more is better). I've never done compiler performance tuning, so I don't know how much effort is required. Second question: does anyone keep track of performance results?

If you can narrow down the example to a simple testcase and attach that to a bugzilla, that would be wonderful. -Chris
