Bug ID: 26684
Summary: False-positive with
CLANG_WARN_NULLABLE_TO_NONNULL_CONVERSION and operator
?:
Product: clang
Version: unspecified
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: co...@gmx.fr
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
The following code produces a false-positive warning with
CLANG_WARN_NULLABLE_TO_NONNULL_CONVERSION:
NSString * _Nullable a = nil;
NSString * _Nonnull b = @"";
NSString * _Nonnull c = a ?: b;
For nullability, Clang should only check the right member of operator `?:`.
