Compiling for 64-bit Solaris 7 on SPARC or UltraSPARC V9 devices is indicated by the -xarch=v9|v9a option. Setting -xtarget=ultra or ultra2 is not necessary or sufficient. If -xtarget is specified, the -xarch=v9 or v9a option must appear after the -xtarget, as in:

-xtarget=ultra -xarch=v9

Otherwise, the -xtarget setting reverts the -xarch value to v8.
