Yes, this is a worry of mine too. > Do you envision that LLVM always be built alongside GHC when bringing up a > new working tree? No - on Tier 1 platforms, I suggest we always provide binary packages for developers to grab. Those same binaries would be shipped with the actual binary distributions we create. On Tier 2 platforms, people may have to compile things, but we can provide some guidelines (and perhaps utilities/scripts) to help manage this. > I suppose there will also be a "make fetch-llvm" > rule to grab a compatible binary snapshot from an archive > for bringing up builds on small machines (presumably these could be > built at least for the first-tier platforms?) Yes, something like that is what I envisioned (a make target or a shell script). > Cheers, > > - Ben -- Regards, Austin Seipp, Haskell Consultant Well-Typed LLP, http://www.well-typed.com/ _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://www.haskell.org/mailman/listinfo/ghc-devs
