      Description

      There are a few manual steps involved in taking the data in the Report.xml file produced by the compiler-dna test run an getting the final numbers to plug into CompilerDNA.java. They are documented on this wiki page: http://docs.codehaus.org/display/RVM/Compiler+DNA

      We do this fairly infrequently, but it would be nice to extend the compiler-dna test run so that the compilationRates and speedupRates arrays could just be copied directly from a field in the Report.xml file. I suspect that for someone who was better at ant than me, this would be a really easy thing to do.

            It would also be nice to watch these values as a performance graph.. this way we can see when we need to update the compiler dna following changes to the RVM.

            I agree with Ian's comment in principle, but gathering the DNA takes a long time. 2-3 hours on a fast IA32 machine and 3-4 hours on a fast PPC machine. Maybe a weekly job given the machine resources we have?
