Description Jens Petersen 2015-03-18 03:00:06 UTC 
Description of problem:
Please enable ld.gold on aarch64.

Scratch build with:

%define gold_arches %ix86 x86_64 %arm aarch64

Comment 1 Jens Petersen 2015-04-21 10:25:54 UTC 
It turns out ld.gold is needed for correct ghc linking on aarch64.

So could you please enable it soon for f22 and f23?

If time is an issue I can also do it - thanks!
Comment 2 Nick Clifton 2015-04-21 16:27:16 UTC 
Hi Jens,

  The new 2.25-7 binutils rpm in rawhide enables support for building GOLD for AArch64.  Please give it a go and let me know if you encounter any problems.

  Has the f23 branch been created yet ?  I could not see it.

Cheers
  Nick

 binutils-2.25-6.fc2 now also contains this patch.

F-23 is the master branch

Thanks!  That is basically what I tested already locally.


On aarch64 using -fuse-ld=gold seems to break:

AC_CHECK_SIZEOF(long long,          8)

I can open a separate bug for AC_CHECK_SIZEOF(long long, 8).

Hi Jens,

> I can open a separate bug for AC_CHECK_SIZEOF(long long, 8).

Please do.

Presumably gold is at fault, but it would be helpful if you could capture the command line used to invoke gold, as well as the object file that it is trying to link.

Cheers

Comment 9 Jens Petersen 2015-04-27 05:57:48 UTC 
Okay I filed bug 1215546.
Comment 10 Jens Petersen 2015-05-21 03:37:15 UTC 
I guess this could be closed now: ld.gold is in F23 Rawhide
