>From what I can see, binutils 2.9.1, released 1/5/1998 (19+ years ago)
already has it for SPARC (according to the man page). :) But binutils
2.8.1 from 20 years ago, still didn't. So it was added between those
versions. :)

I cannot confirm this now, but I'm willing to make a bet that our
generated assembly syntax already depends on newer binutils, for things
like named sections. Although I'm not sure these are enabled for SPARC in
their full glory.
