It's possible not to (iirc at least one arch does that) but please don't change it now. This is a userland ABI issue; GDB knows that the registers are saved, and there are slots for them in sigcontext/ucontext so it would be unexpected if they were not filled in. Could break things like pth. -- Daniel Jacobowitz CodeSourcery
