Hello *, Now that GHC 7.8.[12] is out of the door, the Git reorganization can be tackled further... After a short conversion with Austin and Edward it appears that the sensible course of action with respect towards moving to a proper Git submodule set-up is to fold-in the 5 Git repos listed below (which btw are all GHC wired-in packages) directly into ghc.git (the same way testsuite.git was a few months ago): - base - ghc-prim - integer-gmp - integer-simple - template-haskell IMO, the benefit/cost ratio of simplifying the workflow outweighs the benefit/cost ratio of turning those into proper Git submodules. This incremental step towards a fully git-bisect-able ghc.git does already allow bisecting to work on a larger time-range than it does now, as those wired-in packages are the most likely to break compilation if out-of-sync with ghc.git. If no objections are raised, I'm planning to implement this change next weekend (April 19th/20th). Any comments/questions/...? Cheers, hvr PS: After this step, the next remaining step would be to turn the remaining not-yet-submodule Git repos into proper submodule Repos (like haddock.git) and figure out how to get the sync-all convenience-tooling a bit more submodule friendly...
