/*
Fix up the VCPU state when a syscall is interrupted by a signal.
To do this, we determine the precise state of the syscall by
looking at the (real) rip at the time the signal happened. The
syscall sequence looks like:
1. unblock signals
2. perform syscall
3. save result to RAX
4. re-block signals
If a signal
happens at Then Why?
[1-2) restart nothing has happened (restart syscall)
[2] restart syscall hasn't started, or kernel wants to restart
[2-3) save syscall complete, but results not saved
[3-4) syscall complete, results saved
Sometimes we never want to restart an interrupted syscall (because
sigaction says not to), so we only restart if "restart" is True.
This will also call VG_(post_syscall)() if the syscall has actually
completed (either because it was interrupted, or because it
actually finished). It will not call VG_(post_syscall)() if the
syscall is set up for restart, which means that the pre-wrapper may
get called multiple times.
