2013-04-26[analyzer] An ObjC for-in loop runs 0 times if the collection is nil.Jordan Rose
In an Objective-C for-in loop "for (id element in collection) {}", the loop will run 0 times if the collection is nil. This is because the for-in loop is implemented using a protocol method that returns 0 when there are no elements to iterate, and messages to nil will result in a 0 return value. At some point we may want to actually model this message send, but for now we may as well get the nil case correct, and avoid the false positives that would come with this case. <rdar://problem/13744632> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180639 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-26[analyzer] Model casts to bool differently from other numbers.Jordan Rose
Casts to bool (and _Bool) are equivalent to checks against zero, not truncations to 1 bit or 8 bits. This improved reasoning does cause a change in the behavior of the alpha BoolAssignment checker. Previously, this checker complained about statements like "bool x = y" if 'y' was known not to be 0 or 1. Now it does not, since that conversion is well-defined. It's hard to say what the "best" behavior here is: this conversion is safe, but might be better written as an explicit comparison against zero. More usefully, besides improving our model of booleans, this fixes spurious warnings when returning the address of a local variable cast to bool. <rdar://problem/13296133> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180638 91177308-0d34-0410-b5e6-96231b3b80d8
