[Fixing the subject, it hasn’t been about LLVM for a while]
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
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:
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:
