I forgot to add it to category Makefile, but can't update the revision now, for some reason:

you can rebuild curl without http2 support, that seems to have fixed arc for me

[arrowd]

• Add to category Makefile.

Try to fix messed rev.

• lang/ghc862: Create a port.
• Add to category Makefile.
• Add INTEGER_LIBRARY = %%INTEGER_LIBRARY%% to the build.mk template.

[tcberner]

Make sure this is an svn cp of lang/ghc

extra-patch-aclocal.m4 doesn't apply correctly on arm. The arm part was merged upstream. Only the last hunk is needed (AC_DEFUN([FIND_LD])

[mikael]

The arm patch was merged upstream : https://github.com/ghc/ghc/commit/297879a78cc6ca4c27afb0cc863c8796b60da6e1
patch-configure is not needed anymore.

^ this you can drop now. The svn copy is only for the history of the file. But you created it (I assume).

^ this could probably go in the shared bsd.ghc.mk file, right? (at a later stage)

ghci with DYNAMIC option is fixed on aarch64

We'll need 2 versions of llvm, one for the bootstrap (ghc-8.4 requires llvm50) and one for ghc-8.6 (llvm60)

[arrowd]

• Remove extraneous patches. Add support for BOOT_LLVM_VERSION.

[tcberner]

Looks good to me with the created-by and svn-cp change.

Please prepare a followup for all he ghc-ports to address the order of the first block:
