Yes.  Essentially once this code can load a few .o files, it can load
any of them.  The self build of gclcvs on the Debian autobuilders
works the code heavily.

HEAD is 2.7.0, the active development version, where new features are
added and ansi compliance is approached.  When ready, we will release
it as 2.8.0, following the Linux kernel numbering scheme.  2.6.x is
the stable branch, critical bug fix only (more or less), for maxima,
acl2, axiom, hol88 and nqthm support.

This would be most appreciated, and I'd be happy to lend assistance.
Knowledge of the ia64 reloc definitions is obviously key, though I put
together the alpha version mostly as a guesswork based on the mips
example.  If ia64 were done, we could also share with the lush
project, on which the original sfaslbfd_mips was inspired.  And
someday it would be great to get this back into bfd upstream.

The basic idea is that each section of the .o file has a got table
appended to handle the relocs that refer to the special gp register
value.

Take care,
