In config/sparc.c, there is a comment regarding "Subroutines to support
a flat (single) register window calling convention".  This sounds just
like what I would like to try, but I haven't found anything in the
documentation which describes how I get this to work - whether it is a
compile time option or if a run-time switch.  I want to try gcc
generating SPARC code as if there were only one register window.

How do I do this?

I don't want to touch off a religious war regarding usefulness of
register windows...  Anybody done this and done any performance
measurement with versus without?

Thanks!
