[Bug objc/45763] New: incorrect @encode(BOOL *)
This was reported to me by David Chisnall via email - he mentioned - @encode(BOOL*) - it should return ^c or ^C (depending on whether BOOL is defined as signed or unsigned), but instead it returns *. This is inconsistent with clang and with Apple GCC. I also noticed that we already have a testcase (objc.dg/encode-1.m) but it is only compiled with the NeXT runtime. We should fix it and enable the test on the GNU runtime as well. ;-) Thanks -- Summary: incorrect @encode(BOOL *) Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: objc AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: nicola at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45763

[Bug objc/16398] Dynamic Inheritance in Objective-C
--- Comment #4 from nicola at gcc dot gnu dot org 2010-09-17 09:28 --- This proposed enhancement seems to be a major change to the language! :-) It basically would mean that every object has a customized class hierarchy. So, when a message is sent to the object, the object's custom class hierarchy would need to be traversed - instead of the standard one. (that would indeed complicate messaging quite a lot) When an instance variable of the object is accessed, again the object's custom ivar list would need to be examined to determine the offset of that specific ivar ... instead of using a standard ivar/offset information for all objects. (again this would indeed complicate instance variables quite a lot). I suppose my point is that this object-dependent class hierarchy is not just an enhancement - it is so radical that it would basically transform Objective-C into another language (it's a nice idea though!). ;-) The simpler version of all of this is to be able to replace a class with another one. So, you'd replace 'myRootObject' with 'myDebuggingRootObject' and that would happen everywhere in your application for all the objects. This is called 'poseAs:'. It is clearly much easier to implement than custom replacement of classes for a single object, but it is still quite hard. So hard tha Apple removed it from their runtime and deprecated it. It's no longer available there and probably will be removed from the GNU runtime too. Anyway, if you're interested in this dynamic modifications of class hierarchies, you may want to look into up (and maybe open up a new issue on that). I'd like to close this issue just because the enhancement proposed is too radical. ;-) Thanks -- nicola at gcc dot gnu dot org changed: What|Removed |Added Status|NEW |RESOLVED Priority|P2 |P4 Resolution||WONTFIX http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16398

[Bug objc/32995] False warning when implementing an instance method called `dealloc'
--- Comment #3 from nicola at gcc dot gnu dot org 2010-09-14 22:52 --- If you want to use dealloc for compatibility with Apple Cocoa / GNUstep Base, then you also want the warnings that dealloc needs to include a call to [super dealloc], so I wouldn't change the compiler ;-) You could change your code though - if you're triyng to be compatible with Cocoa / GNUstep, then you may as well define an NSObject root class and have a dealloc method in it ;-) If you still want to use Object, you can add a -dealloc method to Object by using a category: @interface Object (dealloc) - (void) dealloc; @end (the add the implementation). Then you can have the missing [super dealloc] in your subclass, and the compiler won't generate any warnings.
