No, quite the contrary. as is just a (sometimes partial) backport of
Studio fbe, though it's hard to tell exactly which Studio version of fbe
forms the basis of as. Especially for the Solaris 10 as patches, only
particular bugfixes/enhancements have been backported.
Backward compatibility is maintained, of course. as(1) lists
-xarch=v9
Equivalent to: -m64 -xarch=sparc
and many more.
