   8 SYNOPSIS
   9         #include <stdlib.h>
  10         void abort(void);
  11
  12 DESCRIPTION
  13 Use <<abort>> to signal that your program has detected a condition it
  14 cannot deal with.  Normally, <<abort>> ends your program's execution.
  15
  16 In general implementation, <<abort>> raises the exception <<SIGABRT>>.
  17 But for nds32 target, currently it is not necessary for MCU platform.
  18 We can just call <<_exit>> to terminate program.
  19
  20 RETURNS
  21 <<abort>> does not return to its caller.
  22
  23 PORTABILITY
  24 ANSI C requires <<abort>>.
  25
  26 Supporting OS subroutines required: <<_exit>>.
