Bug ID: 16287
Summary: clang should give a better diagnostic for forgetting
the @ in front of an NSString
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Currently:
Nicos-MacBook-Pro:src thakis$ cat test.mm
#import <Cocoa/Cocoa.h>
@interface A
- (void)doFoo:(NSString*)s;
@end
void f(A* a) {
[a doFoo:"asdf"];
}
Nicos-MacBook-Pro:src thakis$ ~/src/llvm/Release+Asserts/bin/clang -c test.mm
test.mm:8:12: error: cannot initialize a parameter of type 'NSString *' with an
lvalue of type 'const char [5]'
[a doFoo:"asdf"];
^~~~~~
test.mm:4:26: note: passing argument to parameter 's' here
- (void)doFoo:(NSString*)s;
^
1 error generated.
Instead it should just say `missing '@' in front of "asdf"`.
