Hi,
I'd like to set up a performance build bot for GHC, but before I can do that I need a script that reliably builds GHC and runs nofib. Do we have such a script? Here's a strawman proposal for one:
cabal install happy alex git clone git://git.haskell.org/ghc.git cd ghc ./sync-all --nofib get perl boot ./configure make cd nofib make clean make boot make -k mode=slow
Questions:
* Does this look sensible? * Is there a way to only build and run a subset of the benchmarks? * Are there any tweaks to mk/build.mk we can do to make the build faster without compromising the results? * Is there a way to do this in a cheap throwaway VM like travis-ci does? Could such a VM already provide GHC and the required libs to make the whole thing hermetic?

I think this ties in with the whole issue of not having nightlies/test bots running. I think if the infrastructure for that was in place then this would simply be a part of the functionality. re: subset of benchmarks, I believe they are just regular tests, in which case you can explicitly pass in which test cases should be ran. Correct me if I'm wrong. -- Mateusz K.
