Is anyone planning on converting the sparc32 target over to use
a target-function-call scheme similar to that of sparc64? ie. so
that it doesn't have to execute code on the stack?
Apparently there is a security setting on Solaris that prohibits
executing code on the stack, even on sparc32, to reduce the risk
of being hacked into, and I'm guessing more and more companies are
going to be adopting it in these uncertain times.

This is from the NEWS file for 6.1:

It should be working?
