* | [ObjC] Emit a boxed expression as a compile-time constant if the | Akira Hatanaka | 2019-03-08 | 1 | -4/+14 |
| | | | | | | | | | | | | | | | | | | expression inside the parentheses is a valid UTF-8 string literal. Previously clang emitted an expression like @("abc") as a message send to stringWithUTF8String. This commit makes clang emit the boxed expression as a compile-time constant instead. This commit also has the effect of silencing the nullable-to-nonnull conversion warning clang started emitting after r317727, which originally motivated this commit (see https://oleb.net/2018/@keypath). rdar://problem/42684601 Differential Revision: https://reviews.llvm.org/D58729 llvm-svn: 355662 | ||||
* | [ObjC] Boxed strings should use the nullability from stringWithUTF8String's ↵ | Alex Lorenz | 2017-11-08 | 1 | -0/+28 |
return type Objective-C NSString has a class method stringWithUTF8String that creates a new NSString from a C string. Objective-C box expression @(...) can be used to create an NSString instead of invoking the stringWithUTF8String method directly (The compiler lowers it down to the invocation though). This commit ensures that the type of @(string-value) gets the same nullability attributes as the return type of stringWithUTF8String to ensure that the diagnostics are consistent between the two. rdar://33847186 Differential Revision: https://reviews.llvm.org/D39762 llvm-svn: 317727 |
