+/* Description: This tests the sigreturn() syscall
+ sigreturn - return from signal handler and cleanup stack frame.
+ When the Linux kernel creates the stack frame for a signal handler,
+ a call to sigreturn() is inserted into the stack frame so that the
+ signal handler will call sigreturn() upon return. This inserted call
+ to sigreturn() cleans up the stack so that the process can restart
+ from where it was interrupted by the signal.
