Summary:
If you cannot set a breakpoint on a particular line of code with
CodeView, make sure you have compiled with both the /Zi and /Od
compiler options to create executable code that has full CodeView
debugging capabilities.
Due to default or other optimization, some code in the executable is
concatenated if the /Od option is not used to disable all
optimization. The sample code below illustrates this situation.
Compiling the code with Zi but not /Od will prevent you from placing a
breakpoint on the indicated line.
Sample Code
-----------
/* Compile options needed: /Zi
*/
#include <stdio.h>
int func();
void main (void)
{
int a,b,c;
a = func(); /* A breakpoint cannot be set on this line because */
b = a + c; /* optimization concatenates it with this line to */
/* achieve this expression b=(a=func())+c. */
}
int func()
{
return(10);
}
