Well, this is where the last and perhaps only use disappeared:
    http://gcc.gnu.org/ml/gcc-patches/1999-09n/msg00661.html

And this is where it was added:

	* sparc.c, sparc.h, sparc.md, sol2.h: Many changes related to V9
	code generation.  Use 64 bit instructions in 32 bit mode when
	possible.  Use V9 return instruction.  UltraSPARC optimizations.
