I asked this question a few weeks back, and got nary a response.

Does anyone know how to enable a flat (single) register window model of
gcc for SPARC?  There's comments in config/sparc.c before some
subroutines which purport to support this feature, but no indication or
documentation (that I could find) about how to enable this feature.  Is
it a run-time switch (e.g.- -fflat_reg)?  Is it a compile-time option?
Is this documented and I just can't find it?

Thanks in advance.
