Compiler Warning (level 3) C4414

'function' : short jump to function converted to near

Short jumps generate compact instruction which branches to an address within a limited range from the instruction. The instruction includes a short offset that represents the distance between the jump and the target address, the function definition. During linking a function may be moved or subject to link-time optimizations that cause the function to be moved out of the range reachable from a short offset. The compiler must generate a special record for the jump, which requires the jmp instruction to be either NEAR or FAR. The compiler made the conversion.

For example, the following code generates C4414:

// C4414.cpp
// compile with: /W3 /c
// processor: x86
int DoParityEven();
int DoParityOdd();
unsigned char global;
int __declspec(naked) DoParityEither()
{
   __asm
   {
      test global,0
      jpe SHORT DoParityEven  // C4414
      jmp SHORT DoParityOdd   // C4414
   }
}
