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]
          [-S] [-K {pic,PIC}] [-o objfile] [-L] [-T]
          [-P [[-Ipath] [-Dname] [-Dname=def] [-Uname]]...]
          [-m [-Ym,path]] [-n] [-ul] [-xF] [-xarch=v7] [-xarch=v8] [-xarch=v8a]

[-xarch=v9b]  [-xcode={pic13,pic32}] file.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.
