/* Testcase to exercise the code path in bug 13961.
|
|
|
|
|
|
|
|
|
|
Compiled from:
|
|
|
|
|
|
|
|
|
|
class foo
|
|
|
|
|
{
|
|
|
|
|
public:
|
|
|
|
|
int bar;
|
|
|
|
|
};
|
|
|
|
|
|
|
|
|
|
foo baz;
|
|
|
|
|
|
|
|
|
|
int
|
|
|
|
|
main ()
|
|
|
|
|
{
|
|
|
|
|
return 0;
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
And then manually edited to insert the necessary DW_AT_specification
|
|
|
|
|
entries to trigger the desired code path.
|
|
|
|
|
There's no real need to make this architecture-specific, so it has been
|
|
|
|
|
further hand-edited to support that.
