            Bug ID: 41674
           Summary: [C++] Initialisation of this from expression with
                    pointer type leads to an invalid bitcast
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: OpenCL
          Assignee: unassignedclangbugs at nondot.org
          Reporter: kevin.petit at arm.com
                CC: anastasia.stulova at arm.com, llvm-bugs at lists.llvm.org

When this is initialiased from an expression with a pointer type, an invalid
bitcast is produced  (it should be an addrspacecast).

The following code allows to reproduce the issue:

---------------------------------------------
struct foo {
    void init() {
        m_data = 1;
    }
private:
    int m_data;
};

kernel void test(global struct foo* afoo) {
    afoo->init();
}
---------------------------------------------

I will be submitting a patch that I believe fixes the issue.
