[LLVMdev] llvm shipping with android ndk for building ghc cross compiler

[Nathan Hüsken]

Hey,

I am trying to build a haskell cross compiler to android by building the
glasgow haskell compiler with target=arm-linux-androideabi.

It builds, but the executables the compiler produces segfaults on my
android device. This is probably not llvm related, but I want to rule
that out.
I used the llvm version shipped with ubuntu 12.10 for the build.

I was wondering if maybe I have to use llvm from the android ndk. If I
do that, compilation fails with the error message at the end of this mail.

1. Do I habe to use llvm shipped with the android ndk, or does it not
matter and I can use llvm from ubuntu?
2. The error message means, that the haskell calling convention is not
supported, correct? Is there some good reason llvm shipping with android
ndk does not support it?

Thanks!
Nathan
