 Build current GHC HEAD on linux-powerpc.

 Usign the stage1 to build ```compiler/main/DynFlags.hs -o
 compiler/stage2/build/DynFlags.o``` I get:

 {{{
 ghc-stage1: panic! (the 'impossible' happened)
   (GHC version 7.7.20121212 for powerpc-unknown-linux):
 Register allocator: out of stack slots (need 147)
If you are trying to compile SHA1.hs from the crypto library then this
is a known limitation in the linear allocator.

Try enabling the graph colouring allocator with -fregs-graph instead.
You can still file a bug report if you like.

 Here is a minimal test case:

 {{{
 foo :: (() - (# #)) - Int
 foo f = case f () of (# #) - 5
 }}}

 GHC crashes with:

 {{{
 ghc.exe: panic! (the 'impossible' happened)
   (GHC version 7.6.1 for i386-unknown-mingw32):
 compiler\codeGen\CgCase.lhs:572:15-61: Irrefutable pattern failed
 for pattern ((CoreSyn.DEFAULT,
 deflt_absC) : others)
 }}}

 Here is the actual function (simplified) that triggered the bug:

 {{{
 foo :: [a] - Int
 foo xs = foldl' (flip seq) () xs `seq` 5
 }}}

Old description:

 Hi

 I would like an extension to the GHC as a library API, so that if I
 have done:

   runStmt someStatement

 I can prematurely terminate the execution.

 I have posted this request on ghc-us...@haskell.org and a more thorough
 explanation can be found there: http://www.haskell.org/pipermail/glasgow-
 haskell-users/2007-May/012613.html

Comment(by simonpj):

 I'm not familiar with the details, but it sounds as if you are any
 chance of a patch?
