SYMPTOMS
C++ functions containing inline assembly routines that store the return value in the AX register may need a return statement added to the function. If the function does not have a return statement, the following error is generated:
RESOLUTION
To resolve this error, create a temporary variable and move the AX register to this variable for the return statement. This will work around the C++ type-checking syntax. If you are using C++ version 8.0 that ships with Visual C++ for Windows NT, then the EAX register must be used instead.
Sample Code
/* Compile options needed: none */ int func(void) { //int a; //Remove this comment to eliminate the error. __asm { mov ax, 02h ;mov a, ax //Remove this comment to eliminate the error. } //return a; //Remove this comment to eliminate the error. } void main(void) { int a; a = func(); }
