Inconsistent Warning Message C2705

rayhall — Mon, 02 May 2016 09:01:27 GMT

Hello,

I am getting this warning only for some of basically the same code. "Warning C2750: Possible loss of data"

I can disable the message, but would prefer not to do this. What is wrong ?

TIM_TFLG1 &= ~(1<<TIM_TFLG1_C0F_MASK); // No warning

TIM_TFLG1 &= ~(1<<TIM_TFLG1_C1F_MASK); // No warning

TIM_TFLG1 &= ~(1<<TIM_TFLG1_C2F_MASK); // No warning

TIM_TFLG1 &= ~(1<<TIM_TFLG1_C3F_MASK); // Get Warning C2705

TIM_TFLG1 &= ~(1<<TIM_TFLG1_C4F_MASK); // Get Warning C2705

TIM_TFLG1 &= ~(1<<TIM_TFLG1_C5F_MASK); // No warning

The micro is the S12XE.

Ray.

Hello Ray

What is the data type of TIM_TFLG1_C0F_MASK~ TIM_TFLG1_C5F_MASK, and what is the data type of TIM_TFLG1? We need to the code context to dig out the reason.

By default, the compiler uses 16bit for the operand “1”of the <<operator in your code. So please add the typecast for this kind of operation to get rid of the warning.

Best Regards
