After some initially positive experience with ghc-7.8-rc1 I’ve decided to upstream most of gentoo fixes.

On rare arches ghc-7.8.3 behaves a bit bad:

  • ia64 build stopped being able to link itself after ghc-7.4 (gprel overflow)
  • on sparc, ia64 and ppc ghc was not able to create working shared libraries
  • integer-gmp library on ia64 crashed, and we had to use integer-simple

I have written a small story of those fixes here if you are curious.

TL;DR:

To get ghc-7.8.3 working nicer for exotic arches you will need to backport at least the following patches:

Thank you!
