[Fixing the subject, it hasn’t been about LLVM for a while] Hi, with the help of Ben I managed to create a GHC 7.8.4-rc1 Debian package that builds on arm and armhf. I had to apply a few patches from GHC HEAD, which I hope can enter 7.8.4. (I’ve marked their tickets as "merge" in trac.) Additionally, I had to fix something related to the pre-ARMv6 spinlock implementation: https://phabricator.haskell.org/D564 Finally, I had to find a reliable way to make ghc (and only ghc!) pass the flags to gcc to make it use the gold linker, but I don’t know if my approach is sensible. See http://ghc.haskell.org/trac/ghc/ticket/9873 I have a patch that seems to work here: https://ghc.haskell.org/trac/ghc/attachment/ticket/9873/saner-linker-opt-han... but I’d rather avoid using non-blessed patches in the Debian package. If using the gold linker is a requirement on armel, maybe that should also be handled in upstream? The patch is rather simple: Index: ghc-7.8.3.20141119/aclocal.m4 =================================================================== --- ghc-7.8.3.20141119.orig/aclocal.m4 2014-12-08 18:49:28.207171714 +0100 +++ ghc-7.8.3.20141119/aclocal.m4 2014-12-08 19:03:06.815522917 +0100 @@ -553,6 +553,10 @@ $3="$$3 -D_HPUX_SOURCE" $5="$$5 -D_HPUX_SOURCE" ;; + arm*) + # On arm, link using gold + $3="$$3 -fuse-ld=gold" + ;; esac # If gcc knows about the stack protector, turn it off.
