I am attempting to build GHC 6.4.1 on AIX 5.1L using
GHC 6.2.1 as the host compiler.
Everything proceeds fine until the crash here.
I believe that the problem is that no content for the
callClobberedRegs defined for AIX. In particular,
powerpc_TARGET_ARCH will be defined, but there is no
clause in that file for PowerPC.
I will attach a build log.
