+FUNCTION
+<<abort>>---abnormal termination of a program
+
+INDEX
+ abort
+
+ANSI_SYNOPSIS
+ #include <stdlib.h>
+ void abort(void);
+
+TRAD_SYNOPSIS
+ #include <stdlib.h>
+ void abort();
+
+DESCRIPTION
+Use <<abort>> to signal that your program has detected a condition it
+cannot deal with. Normally, <<abort>> ends your program's execution.
+
+In general implementation, <<abort>> raises the exception <<SIGABRT>>.
+But for nds32 target, currently it is not necessary for MCU platform.
+We can just call <<_exit>> to terminate program.
+
+RETURNS
+<<abort>> does not return to its caller.
+
+PORTABILITY
+ANSI C requires <<abort>>.
+
+Supporting OS subroutines required: <<_exit>>.
