<pre>
    llvm-cov doesn't expand or count some macros as being run. I'm unsure as to where the issue is coming from.

```C
#include <stdint.h>
#include <stdio.h>

#define my_printf(str, val) printf(str"\n", val);

#define CONFIG_UINT_FULL(foo, initval, desc) uint32_t foo = initval;

#define CONFIG_UINT(foo, initval) CONFIG_UINT_FULL(foo, initval, "")

static CONFIG_UINT(foo, 200);

int main ()
{
        my_printf("Value of foo is %d", foo);
        return(0);
}
```

This is a representative portion of code for our project. I'd expect both the use of `my_printf` and the use of `CONFIG_UINT()` to be expanded, but only `my_printf` is. Here's the coverage generated.
