On both Solaris 10 and 11, as complains:
configure:24069: /usr/ccs/bin/as -xarch=v9d -o conftest.o conftest.s >&5
/usr/ccs/bin/as: "conftest.s", line 4: error: detect global register use not
cov
ered .register pseudo-op
/usr/ccs/bin/as: "conftest.s", line 4: error: detect global register use not
cov
ered .register pseudo-op
configure:24072: $? = 1
Adding
.register %g2, #scratch
.register %g3, #scratch
to the testcase allows the test to be assembled without error.
The Solaris 8 and 9 as errors out with
as: error: unknown option 'xarch=v9d'
usage: as [-V] [-Q{y,n}] [-f[O][if]#] [-q] [-s]

With gas 2.21.1, I get this failure instead:
configure:24069: /vol/gcc/bin/gas-2.21.1 -xarch=v9d -o conftest.o conftest.s

&5
Assembler messages:
Error: invalid architecture -xarch=v9d
Error: unrecognized option -\300v9d
configure:24072: $? = 1
Given that even the latest released gas doesn't support those insns, I
think the testsuite needs to accomodate the possibility that the
assembler used doesn't understand them.

Ok, thanks.
