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
<http://git.haskell.org/ghc.git>
cd ghc
./sync-all --nofib get
perl boot
./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 <http://build.mk> we can do to
make the build faster without compromising the results?
Turn down the stage2 optimisation, and turn off the docs:
GhcStage2HcOpts = -O
HADDOCK_DOCS = NO
BUILD_DOCBOOK_HTML = NO
BUILD_DOCBOOK_PS = NO
BUILD_DOCBOOK_PDF = NO
* 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?
Sure. I occasionally use EC2 for GHC hacking and I had a VM set up with
all the tools ready to work on GHC. (but I assume you mean a local VM;
EC2 is not good for perf measurements)
Cheers,
Simon
