Requiring that ops don't use a stack frame doesn't seem like a realistic
constraint.
It can be done, see my latest patch. Of course there's no point doing it if
there is no real need.

The use of soft-float should be a host decision, not a target decision.
All targets should be converted to use the softfloat.h interface. Hosts can
then choose to use with the softfloat library or the native implementation
depending on the host FP capabilities.
Good, I thought using softfloat.h interface implied softfloat library use.
I'll make an updated Sparc64 patch without any sse mess, and separate the
softfloat.h interface changes.
