[Haskell-cafe] Announcing GHC iOS

Simon Peyton Jones
Great.  Please thank Stephen too.. I don't have his email.

Just go ahead and modify
http://ghc.haskell.org/trac/ghc/wiki/CodeOwners
http://ghc.haskell.org/trac/ghc/wiki/Platforms

I assume iOS will become a tier-2 platform?

Certainly! And I'd be happy to take on maintainership of GHC iOS if that's what you mean - I've committed to a very large project using it so I'll be maintaining it anyway : ). I'd guess Stephen would feel the same.

And thanks so much for the kind words, it means the world! Thank you infinitely for Haskell : ).

Cheers
Luke

Stephen provided some more credits - thanks so much to all!

Three connected projects concerning cross-compilation:

*Registerised ARM support, added using David Terei's LLVM compiler back end with Stephen Blackheath doing an initial ARMv5 version and LLVM patch and Karel Gardas working on floating point support, ARMv7 compatibility and LLVM headaches. Ben Gamari did work on the runtime linker for ARM.

*General cross-compiling, with much work by Stephen Blackheath and Gabor Greif (though many others have worked on this).

*A cross-compiler for Apple iOS. iOS-specific parts were mostly Stephen Blackheath with Luke Iannini on the Cabal patch, testing and supporting infrastructure, also with assistance and testing by Mi?tek Bak and Jonathan Fischoff, and thanks to many others for testing; The iOS cross compiler was started back in 2009 by Stephen Blackheath with funding from Ryan Trinkle of iPwn Studios.

Thanks to Ian Lynagh for making it easy for us with integration, makefile refactoring and patience, and to David Terei for LLVM assistance.

Hi all!
(in case you don't read /r/haskell : ))

Stephen Blackheath and I are extremely happy to report that as of today, GHC can natively build binaries for iOS devices and the iOS Simulator.

You'll find everything you need here: http://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOS

The short of it is you can use "ghc-ios myFiles.hs" to get a universal ARMv7/ARMv7s/i386 static library to drop straight into an Xcode project.

Stephen's already working on some wonderful FRP-powered games, I'm working on a project called SpaceTime that I'll announce shortly, and you may now all begin creating insanely great iOS software using the finest language in the world : ).

Stephen deserves the lion's share of the credit for this project - it's been over 3 years in the making! Many thanks to Maxwell Swadling for generalizing static library builds into a -staticlib flag for GHC, Carter Schonwald for compilation guidance, and the venerable Austin Seipp for reviewing and merging our patches.

Luke Iannini
I will tell Stephen!

I've added iOS as Tier 2 ? I bet we can find a sponsor for a buildbot down
the line ? and I've added myself while I wait to hear from Stephen. It
looks like the mailto links on the wiki (e.g. the names in the Platform
Maintainers section) aren't working, by the way:
http://ghc.haskell.org/trac/ghc/wiki/CodeOwners.

Cheers
Luke

[Haskell-cafe] Announcing GHC iOS

Gabor Greif-2
Hi Luke, devs,

Just a quick question, as I haven't recently built a cross-compiler,
but I have noticed a problem with installation of cross-ghc last time.

$ ls <prefix>/lib/ghc-7.7.20130412

The problem is, that when someone installs a non-cross
compiler the same day, the cross-compiler's
libraries and executables get overwritten
by the non-cross installation :-(

This probably also happens with release versions.

Can you confirm this behaviour with HEAD?

In case yes, should we consider adding a
cross-prefix, like employed in bin/ ?

$ ls <prefix>/bin/powerpc-montavista-linux-gnuspe-ghc-pkg-7.7.20130412

Of course all the links inside must be re-aligned accordingly.

Cheers,

    Gabor

Luke Iannini
Hi Gabor!
Yes, I believe that's still the case (we're working around it by using
different prefixes for each architecture at the moment). And I think we
should definitely do what you propose. I'll see if I can get a patch
together shortly (or if someone already knows exactly what to do and wants
to do it first, feel free! : )).

Cheers
Luke

This is probably where one should start,

https://github.com/ghc/ghc/blob/master/mk/install.mk.in#L108

but be careful with the 'if's in the makefile!

[Haskell-cafe] Announcing GHC iOS

Luke Iannini
Thanks!

This seems to do the trick wonderfully.
-ghclibdir     = $(libdir)/ghc-$(ProjectVersion)
+ghclibdir     = $(libdir)/$(CrossCompilePrefix)ghc-$(ProjectVersion)

I've just done a clean build with this and it's working perfectly.

Hi,

I followed the instructions on the link, downloaded ghc, created build.mk,
etc.,
and configured for ghc-ios-sim. But the make fails with the message below.
Tried installing terminfo (cabal install terminfo) but this didn't help...

ghc $ make
===--- building phase 0
make -r --no-print-directory -f ghc.mk phase=0 phase_0_builds
make[1]: Nothing to be done for `phase_0_builds'.

[Haskell-cafe] Announcing GHC iOS

Luke Iannini
Hi Dominick,
Hm, this should have been fixed by
http://ghc.haskell.org/trac/ghc/ticket/7700 .

When you say you downloaded GHC, do you mean you cloned GHC HEAD (e.g. git
clone git://git.haskell.org/ghc.git ?) ? the patches have only just landed
: ).

Also can you give us an idea of what your build environment is? (OS
version, Xcode version etc)

Cheers
Luke

[Haskell-cafe] Announcing GHC iOS

Dominick Samperi
Hello Luke,

Thanks for the note. I'm testing on OS X 10.8.4, Xcode 4.6.3, and llvm-gcc
4.2.1
(I placed the scripts directory ghc-ios-scripts-master at the front of
PATH).
LVM Build is 2336.11.00.

I fetched GHC sources and tried to build using:

$ git clone git://git.haskell.org/ghc.git
$ cd ghc
$ ./sync-all --no-dph get

$ perl boot # after creating mk/build.mk
$ ./configure --target=i386-apple-darwin11 --prefix=/usr/local/ghc-ios-sim/
$ make

# Fails saying terminfo -any is not available

Great! Do you plan to push this? (Please do!)

[Haskell-cafe] Announcing GHC iOS

Dominick Samperi
In reply to this post by Dominick Samperi
I just tested the GHC support with Xcode 5 and iOS 7 (64-bit) and it
seems to work (using the simulator). But I wonder if an app built on
this framework would pass Apple's QA filtering process, given that
an external binary (.a) file with the Haskell code must be included?

Also, the iPhone 5S is the first with 64-bit support, and for best
performance all apps should be 64-bit (because then no 32-bit libs need
to be loaded, and there are more general purpose and floating point
registers in 64-bit mode). Are there any roadblocks preventing the
creation of 64-bit GHC/iOS7 apps?

Thanks,
Dominick

Yes, it is "just" one: GHC's ARMv8 support is completely missing.

[Haskell-cafe] Announcing GHC iOS

Dominick Samperi
Apple has kept their 64-bit plans secret until recently, but now they want
as many apps as possible to migrate to 64-bit. That may mean a big push for
64-bit support in LLVM, which can be built upon by GHC...

It's not so easy.

1) ARMv8 is already supported in LLVM by work done by ARM folks for some
time.

2) Apple's own private ARMv8 support will be merged with current LLVM
ARMv8 support in the not so near future. See
http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-September/065480.html

3) although GHC on ARM is using LLVM as its backend, you still need to
write some general support code for the architecture itself. See for
example Platform.hs, StgCRun.c, MachRegs.h and some optimization bits
also in LLVM backend -- at minimum.
