Thanks for the patch. Minor nits looking for test cases that should have no
warning (like the two examples provided in the bug).
================
Comment at: clang/test/Sema/warn-uninitialized-statement-expression.c:7
+ int i = ({
+ int z = i; // expected-warning{{variable 'i' is uninitialized when used
within its own initialization}}
+ init(&i);
----------------
Can you please add a case like `foo` without `z` in it (so that no warnings are
expected, as in pr42604)? (You can keep both test cases, just looking for 1
more, as the first case).
================
Comment at: clang/test/Sema/warn-uninitialized-statement-expression.c:20
+ struct widget my_widget = ({
+ struct widget z = my_widget; // expected-warning{{variable 'my_widget' is
uninitialized when used within its own initialization}}
+ int x = my_widget.x;
----------------
Ditto about adding a clear case that should not warn.
================
Comment at: clang/test/Sema/warn-uninitialized-statement-expression.c:21
+ struct widget z = my_widget; // expected-warning{{variable 'my_widget' is
uninitialized when used within its own initialization}}
+ int x = my_widget.x;
+ init2(&my_widget);
----------------
This needs a trailing comment like:
```
int x = my_widget.x; // fixme: we should probably warn about this case
```
and file a bug about it. Doesn't need to be solved here.
