Summary: Warning about struct tag argument being "visible
outside of this function"
Product: clang
Version: trunk
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: Frontend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Compiling this with clang (r125414):
#import <Foundation/NSObject.h>
@interface NSObject(Category)
- (BOOL)appendXML:(struct _OFXMLBuffer *)xml;
@end
now produces a warning that it didn't before.
struct-tag.m:4:27: warning: declaration of 'struct _OFXMLBuffer' will not be
visible outside of this function
- (BOOL)appendXML:(struct _OFXMLBuffer *)xml;
This is easily fixable by #import'ing the header that has a typedef for this
struct, but it has never produced a warning before and seems iffy to me. I'm
not enough of an expert on the C spec to say whether this is a regression or a
new correct behavior, though.
