Bug ID: 23347
Summary: Don't issue -Wtautological-pointer-compare with
-weak_framework
Product: clang
Version: 3.6
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
The recommended way to check for symbols of a framework linked with
"-weak_framework" is:
if (MyWeakLinkedFunction != NULL) {
...
}
This is according to Apple docs:
https://developer.apple.com/library/mac/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html
However, recent clang version (from Xcode 6.3.1) say:
error: comparison of function 'MyWeakLinkedFunction' not equal to a null
pointer is always true [-Werror,-Wtautological-pointer-compare]
if (MyWeakLinkedFunction != NULL) {
^~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~
note: prefix with the address-of operator to silence this warning
if (MyWeakLinkedFunction != NULL) {
^
