C5686: Undefined label <Ident>

[ERROR]

The inline assembler issues this message if an undeclared ident is used but not defined as a label. Note that a spelling error in the name of a variable or register may result in this error as well.

In the following code, the label loop is not defined

  void example (void){

  

    asm { 

  

      cmpwi  r3,0

  

      bne    loop

  

      jne    loop

  

    }

  

  }
