Re: Use VFPv3-D16 FPU for ARM builds

[Jani Monoses <jani.monoses@canonical.com>]

Hello Joachim,

Here's the bug in LP and the trac issue it links to

https://bugs.launchpad.net/ubuntu/+source/ghc/+bug/945396

https://ghc.haskell.org/trac/ghc/ticket/5914

the D16 part was Debian/Ubuntu specific, IIRC we define hardfloat in that particular variant (16 double registers) or we had a different naming for some reason.

I do not recognize the error message in your log though, it was something more telling in the bug I chased down back then.

Unfortunately I do not know about the current status of ARM in GHC. I know Colin Watson worked on ARM64 but that may not translate to ARM.

cheers

Jani

Dear Jani,

you once created a patch against GHC, changing
ARM_ISA_EXT="[VFPv3,NEON]" to ARM_ISA_EXT="[VFPv3D16,NEON]". Is that
still required in GHC 7.8? Did you submit the patch upstream? And may it
be the cause for the build failure at
https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=armel&ver=7.8.20140411-2&stamp=1398720634

Thanks,
Joachim
