Summary: Invalid opcode on AIX

Initial Comment:
Hello, 
 
I am bootscrapping ghc 6.2.1 on AIX5.1L (PowerPC).  
This is an unregisterised bootstrap process. 
 
I have gotten as far as building ghc from the .hc files 
on the AIX machine.  However, the build fails here: 
 
creating libgmp.la 
(cd .libs && rm -f libgmp.la && ln -s ../libgmp.la 
libgmp.la) 
gmake[4]: Leaving directory 
`/home/jgoerzen/programs/unreg/ghc-6.2.1/ghc/rts/gmp'

I do not know PowerPC assembly so I'm afraid I'm 
useless on this one.  However, if I add -mpowerpc to 
the gcc command line, it works. 
 
Along similar lines, gmp's build fails with hosts of 
opcode-related errors.  But if I change the 
ghc/rts/Makefile like this (bootorig is original; boot is 
new), it works: 
 
bootorig :: 
        cd gmp && CC=$(WhatGccIsCalled) ./configure 
--enable-shared=no \ 
                --host=`echo $(HOSTPLATFORM) | sed 
's/i[567]86/i486/g'` 
 
boot :: 
        cd gmp && ./configure --enable-shared=no 
 
Something about --host seems to be confusing gmp.

Yes, you are correct.  I worked around it using a gcc 
wrapper that I have documented here: 
 
http://gopher.quux.org:70/devel/AIX/ghc/secrets.txt 
 
BTW, I have a built source tree and binary dist available at 
http://quux.org/devel/AIX/ghc if you are interested.

Adding -mpowerpc to the compiler options seems to be the right thing to 
do to fix Adjustor.c. I assume that as on AIX only accepts code that is 
compatible with the old (pre-PowerPC) POWER architecture by default 
unless you specify -mpowerpc.
The relevant inline assembler instructions in Adjustor.c are concerned 
with cache flushing and are absolutely for PowerPC chips. All PowerPC 
chips support those instructions.

I've gotten a little farther by now -- after running this 
command from the hc-build script: 
 
$MAKE -C ghc/rts      boot && $MAKE-C ghc/rts      all                          
 
I now see:

mpn/sb_divrem_mn.c 
copying ./mpn/generic/jacbase.c to mpn/jacbase.c
