llc -soft-float does not work


I was trying to use llc with soft-float option to generate soft-float
code for Sparc. But it does not work.
With or without -soft-float option will generate the same code for
llc. Is this still an experimental feature?

It requires some target-specific code to work... and AFAIK nobody has
bothered for SPARC. grep for UseSoftFloat in the source tree if you're
interested in implementing it.
