Re: trouble building ghc-7.4 on Fedora 18 (devel) ARM
A late followup, just to let you know, everything is good now. > Not sure if +d16 is actually essential on Fedora though guess it doesn't hurt. It is... I hope llvm will make it the default for armv7 hardware fp. So finally ghc-7.4.1 is built for Fedora ARM and working: I also had to forward-port my pkgconfig libffi workaround for non-native compiler archs to help the C compiler find libffi.h when building prof libraries. http://arm.koji.fedoraproject.org/koji/buildinfo?buildID=66294 Thanks for everyone's help and particular big kudos and karma to those who did the heavy-lifting on the ARM port for 7.4. Maybe someone has some proper benchmarks but roughly going by the ghc-7.4.1 build it seems over twice as fast as 7.0.4. :-)) Jens ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
Re: trouble building ghc-7.4 on Fedora 18 (devel) ARM
Thanks Joachim, Jani and Karel, Very helpful :) I managed to get access to a Fedora armv7hl box, and running "ghc -v" there on an offending file I saw the argument to llc was: llc -O3 -relocation-model=static /tmp/ghc3749_0/ghc3749_0.bc -o /tmp/ghc3749_0/ghc3749_0.lm_s -mattr=+v7,+vfp3 which is not the expected one: -mattr=+v7,+vfp3,+d16 [-float-abi=hard]. ie the patched line is not the one getting applied... (It seems to me it would be better to fix llvm though? Maybe it is already upstream??) Anyway sorry it seems the reason for the above is that I forget to run aclocal! :-( Not sure if +d16 is actually essential on Fedora though guess it doesn't hurt. Karel, I will try to test your patch later. Thanks Jens ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
Re: trouble building ghc-7.4 on Fedora 18 (devel) ARM
Hi, I've just attached my fix for hard-float ABI build failure on GHC HEAD to the #5914. I would be more than glad if you can attempt to merge it to 7.4.x you are packaging and test if it works for you on both soft and hard float ABI. Hard seems to be preferred these days at least on Linux... If you keep me posted about this either by email or by adding info to bug above, I would really appreciate it. Once you verify the fix is working on 7.4.x I'll push it for inclusion on HEAD even I'm not able to bootstrap it fully (see #6043) and from HEAD it will be merged hopefully to 7.4.x branch to easy your packaging job... Thanks!

Hi Jens,

> Anyway thoughts on how to proceed?
the error message looks as if you are actually building on what Debian
calls armhf, with hard floating point support. According to the Debian
changelog:
ghc (7.4.1-2) unstable; urgency=low
[ Iain Lane ]
* Two new patches (backported by Iulian Udrea) to fix armel build
failures. See upstream bug #5824.
- fix-ARM-s-StgCRun-clobbered-register-list-for-both-A
- fix-ARM-StgCRun-to-not-save-and-restore-r11-fp-regis
* Use dh_autoreconf{,_clean} to autoreconf, mainly so we can have proper
clean support.
* armhf support (thanks to Jani Monoses):
- debian/patches/ARM-VFPv3D16: Use vfp3-d16 FPU for ARM builds.
- debian/patches/armhf_llvm_abi: Pass -float-abi=hard to llc on armhf if
__ARM_PCS_VFP is defined (needs to be preprocessed for this)
- debian/rules: Define __ARM_PCS_VFP on armhf for the above patch.
you might need to set __ARM_PCS_VFP. This is the code in debian/rules:
ifeq (armhf,$(DEB_HOST_ARCH))
echo "SRC_HC_OPTS += -D__ARM_PCS_VFP" >> mk/build.mk
endif
It seems that these patches, or rather the fixes, were already submitted
upstream, but need more cleanup
(http://hackage.haskell.org/trac/ghc/ticket/5914)
FTR, here are the patches:
http://patch-tracker.debian.org/patch/series/view/ghc/7.4.1-2/ARM-VFPv3D16

trouble building ghc-7.4 on Fedora 18 (devel) ARM
Hi, I have been struggling to build ghc74 on ARM (ideally with llvm3) on Fedora 18 (the current development tree). After applying 4 recent ARM patches from Debian the ghc-7.4.1 build gets to: : "inplace/bin/ghc-stage1" -H32m -O-package-name base-4.5.0.0 -hide-all-packages -i -ilibraries/base/. -ilibraries/base/dist-install/build -ilibraries/base/dist-install/build/autogen -Ilibraries/base/dist-install/build -Ilibraries/base/dist-install/build/autogen -Ilibraries/base/include -optP-DOPTIMISE_INTEGER_GCD_LCM -optP-include -optPlibraries/base/dist-install/build/autogen/cabal_macros.h -package ghc-prim-0.2.0.0 -package integer-gmp-0.4.0.0 -package rts-1.0 -package-name base -XHaskell98 -XCPP -O2 -no-user-package-conf -rtsopts -odir libraries/base/dist-install/build -hidir libraries/base/dist-install/build -stubdir libraries/base/dist-install/build -hisuf hi -osuf o -hcsuf hc -c libraries/base/dist-install/build/GHC/Event/Clock.hs -o libraries/base/dist-install/build/GHC/Event/Clock.o [parallel build line removed] /usr/bin/ld: error: /tmp/ghc5703_0/ghc5703_0.o uses VFP register arguments, libraries/base/dist-install/build/GHC/Event/Clock.o does not /usr/bin/ld: failed to merge target specific data of file /tmp/ghc5703_0/ghc5703_0.o collect2: error: ld returned 1 exit status make[1]: *** [libraries/base/dist-install/build/GHC/Event/Clock.o] Error 1 (full build log at: http://arm.koji.fedoraproject.org/koji/getfile?taskID=723311&name=build.log and more details at http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=723311) I gather that it builds on Debian so I am not quite why it is failing on Fedora.
