I think this needs a `REQUIRES: system-darwin`.
For science, I also tried to make a version of this test which could run on
other systems, but all I managed is to hit an (lldb)assert:
```
$ cat a.m
__attribute__((objc_root_class)) @interface Foo {
int y;
}
@end
#ifdef DEF
@implementation Foo {
int i;
}
- (id)init {
self->i = 1;
self->y = 2;
return self;
}
@end
#endif
Foo *foo;
$ clang -c a.m -g -DDEF --target=aarch64-apple-macosx
$ lldb a.o -o "target variable foo[0]"
(lldb) target create "a.o"
Current executable set to '/tmp/a.o' (arm64).
(lldb) target variable foo[0]
warning: trying to determine the size of type @interface Foo{
int y;
int i;
}
@end
without a valid ExecutionContext. this is not reliable. please file a bug
against LLDB.
