Comment:
Yeah this is a known issue. On Mac OS X things should work but on Linux
and Windows LLVM has changed how section labels are handled and so this is
the problem.
A work around is this. Put the attached script on your path before the
system 'as' program so it runs instead. Basically the script runs sed over
the assembly to fix up the labels before running 'as' as usual.
Otherwise you'll have to wait for the next GHC release. LLVM 2.9 works
fine otherwise. I actually helped fix 2 fairly major bugs in the RC's to
make sure of this.
