Title: anonymous unions problem
Post by: davehohl on October 27, 2015, 08:23:51 PM

Version 20 seems to get confused by anonymous unions. For version 20 the symbol coloring for the member function below shows params.cumulativeTestCount in red (unknown symbol) and if I hover over it I get "Symbol color:symbol not found."

Version 19 handles it fine.

I did already retag the project for version 20.

Here is the function (in .cpp file):

void ConfigParams::setCumulativeTestCount(U32 count)
{
    params.cumulativeTestCount = count;
    updateCrc();
    (void)writeToEeprom();
}

Here is the class definition (in .h file):

class ConfigParams
{
    friend S16 debugFunctions(void);

    public:
        ConfigParams(void);
        ~ConfigParams(void);

        U32 getCumulativeTestCount(void) const;
        U32 incrementCumulativeTestCount(void);
        void setSerialNumber(const Char *serNum);
        void getSerialNumber(Char *serNum) const;

        static bool initialize(void);
        bool crcIsValid(void) const;
        bool readFromEeprom(void);
       
    private:
        union
        {
            struct
            {
                U32 cumulativeTestCount;
                Char serialNumber[SERIAL_NUMBER_LENGTH];
            } params;

            // raw element ensures that the size of the class is a multiple
            // of 4 bytes, with the CRC in the last 2 bytes (assuming
            // DEVICE_CONFIG_EEPROM_BYTES is a multiple of 4 bytes)
            U8 raw[DEVICE_CONFIG_EEPROM_BYTES - sizeof(U32)];
        };
        U16 pad;    // needed to align crc in last two bytes of the block
        U16 crc;

        void updateCrc(void);
        bool writeToEeprom(void) const;
        void setCumulativeTestCount(U32 count);
};

Reproduced.  This one may have to go into a hot fix or the first patch.

This will be fixed in RC4.  You will need to rebuild your tag file.

Hero point for the excellent example.

This is indeed fixed in RC4. Thanks!
