I am pleased to announce the arrival of ghc version 9 (9.2.6) and Haskell
packages based on Stackage LTS 20 versions in Rawhide and F38
<https://bodhi.fedoraproject.org/updates/FEDORA-2023-7a3a4921e3>.
This landed in f38 and f39 today for
https://fedoraproject.org/wiki/Changes/Haskell_GHC_9.2_and_Stackage_20.
With ghc 9.2 there are some significant performance improvements
particularly for aarch64 (with its new Native Code Generator compilation
times are now on par with Intel arch's) and also s390x gains a llvm
backend, which also improves build times a lot. (ppc64le is now the slowest
ghc arch in current Fedora). Also Haskell packages' modules are now built
in parallel in Koji for further build speed ups.
There are still a small handful of packages which didn't build yet, which I
will be sorting in the next days (the only significant ones are the gi-gtk
and dhall stacks).
If you see any problems please let me know or open a bug.
Jens
