* haskell-cabal.eclass: drop unused CABAL_FEATURES="alex happy c2hs cpphs"Sergei Trofimovich2016-09-131-66/+7
| | | | | | | | | | | | | | | | | | | | | | While at it: - dropped internal 'ghc-sanecabal()' helper - factored out parallelism setup to new 'ghc-make-args()' function - building initial Setup binary now also uses 'ghc-make-args()' - dropped unused CABAL_MIN_VERSION global variable Fixed bug in 'ghc-make-args()' to work on NOSMP ports of GHC: We use 'qb0' to enable parallel GC. Parallel GC requires SMP support and threaded runtime. Reported by iota__ on arm/ghc-8 where there is support for parallel make but not the SMP support: ,("Host platform","arm-unknown-linux") ,("Support SMP","NO") ,("Support parallel --make","YES") ,("RTS ways","l debug thr...

* haskell-cabal.eclass: unleash full parallelism of parallel ghcSergei Trofimovich2016-09-021-12/+8
| | | | | | | | | | | | | | | | | | | I've explored scalability of 'ghc --make -j' a bit in https://ghc.haskell.org/trac/ghc/ticket/9221 Some takeaways: - never specify -j<N> with N > CPU. garbage collector threads waste kernel time running sched_yield() - GHC allocates A Lot: large nursery decreases GC interruptions. We fix it with '-A256M' - for large nursery enabling work-stealing makes GC finish faster on each collection cycle. We fix it with -qb0 While at it move HCFLAGS setup after parallel defaults. That allows user to override defaults with own HCFLAGS. Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* haskell-cabal.eclass: drop IUSE=hoogleSergei Trofimovich2016-06-011-1/+3
| | | | | | | | | | commit 2db4176c329e5e99e68f47dcb058c55d434bb64e accidentally exposed IUSE=hoogle to ::gentoo. It's meant to be used only in ::haskell. The patch reverts accidental change back. Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H.
