Comment (by kgardas):

 Hi Sergei,
 I've just attached {{{git diff}}} in my sparc registerised build tree.
 It's really old, so probably bit rotted more or less but perhaps you may
 find it at least a little bit helpful. If I remember correctly, this was
 able to get GHC running and the majority of failures were caused by bug in
 show of double type -- hence my attempt to test this in
 bindisttest/HelloWorld.lhs. The issue was in register mapping while
 traversing calls from Haskell to C and back in showPrec function IIRC.
 Otherwise it kind of worked at least somehow.
 I'll not have time to resurrect my attempts on SPARC for a few upcoming
 months at least but would be glad if you can have a look at it.
 I'm surprised you are using sparc linux. I've thought Linux is not well
 supported on SPARC. My reference hence was always Solaris, but due to
 recent Oracle movements w.r.t. this OS I'm moving away from it to OpenBSD
 land...
 Thanks! Karel
