Like hundreds. Most are "bad stderr" or "stderr mismatch". I notice a lot of tests complaining about "unable to decommit memory: Function not implemented". This may be the cause of all the failures. Any idea what it's about?

I'm afraid not. For the record, I have nightly ARM builds available [[http://home.smart- cactus.org/~ben/ghc/nightlies/arm/20160209/|here]]. They are built on an ARMv7 board running Debian 8.

IN addition, however many problems there are with Armv7, the ones with Armv7 are significantly worse. Debian shipped a working ghc-7.8.4, but the current ghc-7.10.3 is completely busted due to a bug in LLVM that was never fixed. I've been using Debian's old ghc-7.8.4 to build the GHC 8.0 branch, but I currently cannot build Git HEAD because git head requires ghc-7.10. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11206#comment:23 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
