once you switch to `-verify` you can switch to the diagnostic test syntax, e.g:
```cpp
void b(__attribute__((opencl_global)) int(*) );
// expected-error@-1 {{passing 'int (*)()' to parameter of type '__global int
(*)' changes address space of pointer}}
```
over time you'll get more familiar with the full features, but for now the
basic syntax is
```
// expected-{error,warning,note,remark}@location {{the error, warning, note, or
remark text}}
```
For simple tests like this having a location of `-N` means "N lines
previously", you can also have labeled locations, but that becomes more useful
once you're making changes that require extensive tests.
