Is there any way I can see the detailed logs of the failure ?
If it's the same problem that IainS reported to me privately, then it's caused
by a bug in the Apple testcases (objc-foreach-1.m etc) --
@implementation MyList
- (unsigned int)countByEnumeratingWithState:(struct __objcFastEnumerationState
*)state objects:(id *)items count:(unsigned int)stackcount
{
return 0;
}
@end
the return value should be 'long unsigned int', not 'unsigned int', and so for
'stackcount'.
What happens then is that the ObjC code generates a method call
returning/taking a 'long unsigned int', but the prototype says 'unsigned int',
and a gimplify check fails and aborts compilation.
I would imagine a fix would entail:
* having the ObjC FE check that countByEnumeratingWithState:objects:count: has
the expected method signature; if not, produce an error. The testcases would
still fail, but with an informative message rather than an internal compiler
error :-)
* fix the testcases (and add a testcase for the above error).
Thanks
