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

+Description: Use native x86_64 instructions on x32
+ This patch enables a few native 64-bit integer instructions
+ on x32 which are available on this architecture despite using
+ 32-bit pointers. These instructions are present on x86_64 but
+ not on x86 and ghc checks the size of (void *) to determine
+ that. This method fails on x32 since despite using 32-bit
+ pointers and hence sizeof(void *) == 4, it still uses the
+ full x86_64 instruction set and software-emulated variants
+ of the aforementioned 64-bit integer instructions are
+ therefore not present in the toolchain which will make ghc
+ fail to build on x32.
+ See: https://ghc.haskell.org/trac/ghc/ticket/11571
