> > I'm only talking about changing Darwin. > Sorry, I meant pushing the gcc callee-saved registers in the assembly sigtramp functions (for example in sys_darwin_amd64.s) as it is done in crosscall2. I ran into the issue, that the content in the rbx register was overwritten by the sigfwdgo() function as plan9 does not have the same register saving rules.
