cross-toolchain build script; problem with gas for sparc64

[Dan Kegel <dank@kegel.com>]

Hey folks,
I spent some time trying to get crosstool (my gcc/glibc cross toolchain
build script) to support the sparc64-linux target.  It might be of
interest for anyone who needs to build gcc and glibc but doesn't
have the target handy (or who wants to do a clean build from fully
pristine sources).  Its home page is http://kegel.com/crosstool

To build a gcc-3.4.0/glibc-2.3.2 toolchain targeting sparc64-linux
with the current version of my script, you'd do
   wget http://kegel.com/crosstool/crosstool-0.28-rc7.tar.gz
   tar -xzvf crosstool-0.28-rc7.tar.gz
   cd crosstool-0.28-rc7
   sh demo-sparc64.sh

Sadly, this fails at the moment with
   qp_qtoi.s:261: Error: Illegal operands: There are only 32 single precision f registers; [0-31]
while building glibc.
(See also http://sources.redhat.com/ml/binutils/2004-04/msg00686.html)
Anyone seen that kind of error before?  It's odd, since the assembler is
being passed the -Av9a -64 options, which really ought to tell it
there are 64 fp registers, I thought.

Thanks,
Dan
