Code Review usage yields rule M12.6 messages

Troubleshooting


Problem

Attempts to use Code Review component for IBM Rational Test RealTime render the rule M12.6.

Symptom

When you run Code Review on the example below, you get unexpected output.

#include <stdint.h>

static void yad(void);

extern uint16_t try_something(void);

static void yad(void) {

    uint16_t Attempts = 42u;

    uint16_t Error = 0u;

    do {

             Error = try_something();

             Attempts--;

          }

    while((Attempts != 0U) && (Error != 0u));

}




The code review checker (crccc) then shows the following output.


script C:\Program Files\Rational\TestRealTime\lib\scripts\Source.pl

gcc.exe -c "C:\testcase\code.c"    -g  -o "cpcgnu\code.o"

Done


Code Review checker reports error on the while(...) statement :


Rule M12.6.2:The operator on a Boolean expression should be a logical operator ( &&, || or !).

Rule M12.6.1:Only Boolean operands should be used with logical operators (&&, || and !).
