| /* We need our own copy of VG_(do_syscall)() to handle a special |
| race-condition. If we've got signals unblocked, and we take a |
| signal in the gap either just before or after the syscall, we may |
| end up not running the syscall at all, or running it more than |
| once. |
| |
| The solution is to make the signal handler derive the proxy's |
| precise state by looking to see which eip it is executing at |
| exception time. |
| |
| Ranges: |
| |
| vga_sys_before ... vga_sys_restarted: |
| Setting up register arguments and running state. If |
| interrupted, then the syscall should be considered to return |
| ERESTARTSYS. |
| |
| vga_sys_restarted: |
| If interrupted and eip==vga_sys_restarted, then either the syscall |
| was about to start running, or it has run, was interrupted and |
| the kernel wants to restart it. eax still contains the |
| syscall number. If interrupted, then the syscall return value |
| should be ERESTARTSYS. |
| |
| vga_sys_after: |
| If interrupted and eip==vga_sys_after, the syscall either just |
| finished, or it was interrupted and the kernel doesn't want to |
| restart it. Either way, eax equals the correct return value |
| (either the actual return value, or EINTR). |
| |
| vga_sys_after ... vga_sys_done: |
| System call is complete, but the state hasn't been updated, |
| nor has the result been written back. eax contains the return |
| value. |
