I've seen that gcc for Sparc has an option to generate "flat" code
not using register windows. Have you considered using that ?
I already played with this :-)
It's not usable because due to a bug in gcc when you
use -mflat it doesn't honor -fno-delayed-branch.
I have to use -fno-delayed-branch so that the instructions emitted for
the op-i386.o routines don't have pieces moved into the delay slot of
the sparc return instruction.
I have test-i386 fully passing except for 3 float tests at this
point. Once I resolve that I'll start playing with using shared
libraries and things like that.
