[Qemu-devel] [PATCH v3 0/9] Third try at fixing sparc register allocation

[Richard Henderson]

I was unhappy about the complexity of the second try.

Better to convert to normal temps, allowing in rare
occasions, spilling the "globals" to the stack in order
to satisfy register allocation.

I can no longer provoke an allocation failure on i686.
Hopefully this fixes the OpenBSD case that Mark mentioned
re the second attempt.
