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
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?
