"My quick guess at the cleanest fix would be to move the 32-bit
version to the
i86 subdirectory and then make /usr/bin/tclsh8.5 a link to
amd64/tclsh8.5
or sparcv9/tcls8.5. (I'm guessing there are times you might want the
32-bit
version, especially if you have loadable .so modules that may be
loaded for
extensions that haven't been ported to 64-bit yet. Otherwise you'd just
drop the 32-bit and move the 64-bit into the main directory, like we
did with
the Xorg binary after the 32-bit EOF.) "
I suggested that over isaexec, since on Solaris 11, where there are
only 64-bit
kernels, isaexec is just an additional chunk of code that results in
always
running the 64-bit binary. (Unless you have more binary flavors,
such as ones
explicitly tuned for sun4u vs sun4v or something - isaexec can support
more
complex choices than just 32-bit vs. 64-bit, but I don't know of
anywhere in the
OS we've done that.)
We didn't get all the existing isaexec usage in the WOS removed after
the 32-bit
kernel EOF - perhaps another bug should be filed to make Userland
consistent and
non-isaexec'ed in all the areas that ship 32-bit & 64-bit versions
still, or to
drop 32-bit versions where both are shipped and only one is needed
(like top).
Of course that means downstream projects like OpenIndiana & other
distros which
still support 32-bit kernels have to patch in isaexec on their own,
but this
wouldn't be the first time they've had to compensate for the 32-bit
EOF in the
bits we still share.
If Mike is planning to fix top by removing the isaexec link, then it looks
like your approach is the preferred one.
So here's variant #2 (based on your first suggestion of also including
the 32 bit version):
http://jurassic.us.oracle.com/~richb/6857103-v2/
The package has been reinstalled in the test-6857103 BE mounted at /mnt
on stard.us.oracle.com.
Thanks.
