1.75 New (wrong) information message for missing function (but is a macro)

[versat]

For code like this:

#define BUTTON_PORT_NUMBER 2
#define BTN_PIEZO_PIN (0x04)

/// Helper macro to concatenate the parameters
#define CONCATENATOR(x, y) x ## y
/// Helper macro to evaluate the parameters before concatenating
#define EVALUATOR(x, y) CONCATENATOR(x, y)
/// Helper macro to evaluate button port number and add it to 'P'
#define BUTTON_PORT EVALUATOR(P, BUTTON_PORT_NUMBER)

/// Direction port for button
#define BUTTON_PORT_DIR  (EVALUATOR(BUTTON_PORT, DIR))

void func(void)
{
    BUTTON_PORT_DIR &= (uint8_t)(~BTN_PIEZO_PIN);
}

I get the message:
Id: checkLibraryFunction
Summary: --check-library: There is no matching configuration for function EVALUATOR()
wherever i use BUTTON_PORT_DIR.
Maybe an issue with the new preprocessor?
For the exact same code with 1.74 there was no such message.
Is it worth a ticket?

Please try cppcheck -E

cppcheck -E file.c

If that output looks wrong, for instance if EVALUATOR is not expanded, please open an issue in the simplecpp issue tracker:

The output with -E for the above code is:

void func ( void )
{
 (  EVALUATOR(P,2)DIR  ) &= ( uint8_t ) ( ~  (  0x04  ) ) ;
}

EVALUATOR is only expanded once.
I will create an issue for this.
