Unreg build fails when haddocking dph-seq
The unregisterised HEAD build is failing thus:
"inplace/bin/ghc-cabal" haddock dist-install libraries/dph/dph-seq --with-haddock=/64playpen/buildbot/x86_64-linux-head-unreg/build/inplace/bin/haddock --with-ghc=/64playpen/buildbot/x86_64-linux-head-unreg/build/inplace/bin/ghc-stage2 --hyperlink-source Running Haddock for dph-seq-0.4.0... Preprocessing library dph-seq-0.4.0... Running hscolour for dph-seq-0.4.0... Warning: The documentation for the following packages are not installed. No links will be generated to these packages: ffi-1.0, rts-1.0 haddock: panic! (the 'impossible' happened) (GHC version 6.13.20091112 for x86_64-unknown-linux): This compiler was built without a native code generator Use -fvia-C instead Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
Presumably because dph-seq needs to do some dynamic compilation for its annotations, so Haddock tells it to use -fasm, but there's no native code generator.
Not clear whether this is a Haddock problem or something we need to fix in the GHC API (probably both).
