            Bug ID: 26455
           Summary: no warning about implicit integer to pointer
                    conversions on x86_64
           Product: clang
           Version: unspecified
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

I noticed the [CLANG_WARN_INT_CONVERSION, -Wint-conversion] produces a warning
when implicitly converting a pointer into an integer for the ARM architectures,
but not for x86.

steps to reproduce: 
- in Xcode, create a project for iOS
- add an ObjC method that has a BOOL as return type, but returns a pointer in
the implementation
- build for armv7/arm64 (generic iOS device) - will produce a warning
- build for x86_64 (iOS simulator) - no warning!

Apple LLVM version 7.0.2 (clang-700.1.81)
Xcode 7.2.1 
OS X 10.11 El Capitan
