x86 -> alpha cross compiler

[Jim Dinan <flatline at student dot umass dot edu>]

Hi everyone,

I am trying to build an i686-linux -> alpha-dec-osf4.0 cross compiler
and I'm having a some trouble getting gas to compile.  Here's what I'm
doing on my Pentium III Debian-Woody box:

configure --target=alpha-unknown-osf4.0 --prefix=$HOME/cross
make

The process fails on gas/config/tc-alpha.c.  I had to specify unknown
rather than dec because configure complained that ld and gas didn't know
what I was talking about.  The messages are:

------------------------------------

So, I added the #ifdef RELOC_OP_P mentioned by Alan Modra for targetting
alpha-dec-vms from this message
(http://sources.redhat.com/ml/bug-binutils/2002-q2/msg00017.html). 
There were still a bunch of warnings, but it built.  However, the final
product fails to actually assemble anything.  It says "unknown opcode"
for most, if not all, of the load ops, and gives an "inappropriate
arguments" for jmp and ret ops.

My question is: Is it possible to build this cross compiler?  What am I
doing wrong? ..and.. What version of binutils should I use?  (I tried
2.12, BTW)

Thanks in advance,

- jim.
