Aurora SPARC Linux 1.0 (Ansel) Ultra1 single UltraSparc I sun4u:

binutils 2.13.90 20030212 sparc64-linux
bison-1.35-1
dejagnu-1.4.2-10 (ftp://ftp.redhat.com/pub/redhat/linux/rawhide/SRPMS/SRPMS)
expect-5.32.2-67
gcc-2.96-113
glibc-2.2.5-42
glibc-kernheaders-2.4-7.16sparc
glibc64-2.2.5-42
kernel-2.4.19-1.2sparc (from Aurora SPARC Linux 0.42)
tcl-8.3.3-67

This is how it looks like on this machine, yes, I have a few
sparcs..., (using sparc32 and then for target sparc-linux):

Attached is the saved sparc-nat.i.sparc32.gz and
sparc-nat.i.sparc64.gz for the respective target cases.

Cheers,

(Anyone else tried this to confirm my findings or to tell me what a
fool I am enlighten me on how to debug sparc64 binaries... )
