dll-split

2017-08-29 Thread lonetiger 
Hi All,

I have just killed off dll-split, this means that you no longer need to 
maintain a list
of modules in GHC.mk.

If you’re a non-Windows programmer you can stop reading here, for those that 
build on Windows:

The replacement for dll-split is called gen-dll, and it is able to 
automatically partition any library we build, so this issue is hopefully solved 
once and for all.

Currently dynamic linking is still turned off as I have a few more patches to 
upstream. When I do turn it on, by default you will get a large ~45min hit in 
compile time. This is because dlltool which BFD based is quite slow.

To mitigate this gen-dll supports the use of the msys2 project’s genlib tool. 
This tool finishes in seconds instead of tens of minutes like dlltool.

To install it just run pacman -Sy mingw-w64-$(uname -m)-tools-git

The wiki pages have been updated accordingly already. If you install this now 
you won’t notice any difference in build time later.

Thanks,
Tamar

Very nice, it worked out of the box for me! (Almost, small issue with
https://github.com/mpickering/core-kythe/issues/10.)

I like how you can just add package names to a file and everything
magically works without setup effort.
