The available operators are listed below in the order of evaluation
precedence. Parentheses are also allowed in expressions to change
the order of evaluation.
-, ~
Unary two's complement, unary one's
complement. The unary two's complement
operator is not allowed on constants
containing don't care bits.
*, /, %
Integer multiply, divide, and modulo. These
operators are not allowed on constants
containing don't care bits.
+ , -
Addition, subtraction. These operators are
not allowed on constants containing don't
care bits.
&
Bitwise AND.
|
Bitwise inclusive OR.
Values, symbols, and operators may be used together in analysis
specification expressions. For example, if the local symbol exists,
the following is a valid expression:
file.c:symb+0b67dh&0fff00h
Suppose you want to look at the execution of the sample program
after the address of AGAIN label (406H) occurs. To trigger on the
address of label AGAIN, enter:
trace after AGAIN <RETURN>
The "after" option in the command above supplies trigger position
information. It says that states captured after the trigger should be
saved; in other words, the trigger is positioned at the top of the
trace. You can also specify that the trigger be positioned in the
middle of the trace (about) or at the end of the trace (before).
