<pre>This is a regression somewhere between clang revision
`llvmorg-14-init-7378-gaee49255` and `llvmorg-14-init-8281-gaa1d32f5 - build
7378 has expected behavior.
Repro:
1. Save code below to file file `a.m`
2. Compile code: `bin/clang -Wreturn-type -Wno-objc-root-class -c -o a.o a.m`
```
@interface Bar
- (Bar*)baz;
- (Bar*)quux;
- (int)query;
@end
@implementation Bar
- (Bar* ) baz
{
@try {
@throw self;
} @catch (Bar*) {
return self;
}
return (Bar*)0;
}
@end
```
Expected behavior:
compilation is free from warnings
Actual behavior:
$ bin/clang -Wreturn-type -Wno-objc-root-class -c -o a.o a.m
a.m:14:1: warning: non-void function does not return a value in all control
paths [-Wreturn-type]
}
