Bug#814657: ghc: Please add initial platform support for x32

[John Paul Adrian Glaubitz]

Source: ghc
Version: 7.10.3-7
Severity: normal
Tags: patch

Hi!

I recently bootstrapped ghc on x32.

To achieve that, the following changes were necessary:

 * patch rts/Linker.c to use native 64-bit integer instructions on x32
 * build the compiler unregisterised even though x86_64 has a NCG
   which needs some work to support x32 though
 * use integer-simple by default on x32 since integer-gmp currently
   has issues on x32 (sizeof(mp_limb_t) != sizeof(void *) is unsupported)

The first patch is more discussed by upstream in detail in [1], since they
were not sure yet whether the simple patch that I am using is safe not to
break anything on other platforms.

Attaching a debdiff with my changes in any case so that a discussion can
be started.

Cheers,
Adrian
