--------------------------------+-------------------------------------------
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.
