Re: nofib output difference
I fear that one is my fault. This should fix it: https://phabricator.haskell.org/D5426 I did not want to add a large binary file to the repo so instead compress generated the out file during boot. Which used to work well on my box. However make boot also creates the dependency files that guarantee the proper build order. Turns out sometimes we end up trying to build the compress executable before building the dependency file, so the build fails. I've just gave in to storing the output file in the repo now. ___ ghc-devs mailing list ghc-devs@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs
Understanding bind in template haskell
Hi, In the function DsMeta.repE there is a format being repeated: For example in: repE e@(ExplicitTuple _ es boxed) | not (all tupArgPresent es) = notHandled "Tuple sections" (ppr e) | isBoxed boxed = do { xs <- repLEs [e | (dL->L _ (Present _ e)) <- es] ; repTup xs } | otherwise = do { xs <- repLEs [e | (dL->L _ (Present _ e)) <- es] ; repUnboxedTup xs } There is `(dL->L _ (Present _ e)) <- es`. I don't understand how this type checks correctly. If I'll try to do data Foo a = Foo a runQ [| Foo b <- Foo 1 |] in ghciI get an error. What is the difference?
